makesfx.c source for MakeSFX, without which UnZipSFX is not usable
Notes:
The crc_68.a source file is not currently used by the SAS/C makefile,
nor is flate.a; as of UnZip 5.2 neither of these wants args in
registers.
The DICE makefile has been removed since no one is supporting that
compiler anymore.
As of UnZip 5.2, if you have AmigaDOS 2.1 or newer and have set your
timezone in the Locale preferences editor, this will be an adequate
substitute for setting TZ. If you do not set TZ to your current timezone,
files will be restored with times corrsponding to "EST5EDT", U.S. Eastern
time. See ../proginfo/timezone.txt for directions on how to set the
TZ variable.

; crc_68 created by Paul Kienitz, last modified 04 Jan 96.
;
; Return an updated 32 bit CRC value, given the old value and a block of data.
; The CRC table used to compute the value is gotten by calling get_crc_table().
; This replaces the older updcrc() function used in Zip and fUnZip. The
; prototype of the function is:
;
; ulg crc32(ulg crcval, uch *text, extent textlen);
;
; On the Amiga, type extent is always unsigned long, not unsigned int, because
; int can be short or long at whim, but size_t is long.
;
; If using this source on a non-Amiga 680x0 system, note that we treat
; a0/a1/d0/d1 as scratch registers not preserved across function calls.
; We do not bother to support registerized arguments for crc32() -- the
; textlen parm is usually large enough so that savings outside the loop
; are pointless.
;
; Define NO_UNROLLED_LOOPS to use a simple short loop which might be more
; efficient on certain machines with dinky instruction caches ('020?), or for
; processing short strings. If loops are unrolled, the textlen parm must be
; less than 512K; if not unrolled, it must be less than 64K.

*/
/* HISTORY/CHANGES
* 2 Sep 92, Greg Roelofs, Original coding.
* 6 Sep 92, John Bush, Incorporated into UnZip 5.1
* 6 Sep 92, John Bush, Interlude "FileDate()" defined, which calls or
* redefines SetFileDate() depending upon AMIGADOS2 definition.
* 11 Oct 92, John Bush, Eliminated AMIGADOS2 switch by determining
* revision via OpenLibrary() call. Now only one version of
* the program runs on both platforms (1.3.x vs. 2.x)
* 11 Oct 92, John Bush, Merged with Zip version and changed arg passing
* to take time_t input instead of struct DateStamp.
* Arg passing made to conform with utime().
* 22 Nov 92, Paul Kienitz, fixed includes for Aztec and cleaned up some
* lint-ish errors; simplified test for AmigaDOS version.
* 11 Nov 95, Paul Kienitz, added Agetch() for crypt password input and
* UnZip's "More" prompt -- simplifies crypt.h and avoids
* use of library code redundant with sendpkt(). Made it
* available to fUnZip, which does not use FileDate().
* 22 Nov 95, Paul Kienitz, created a new tzset() that gets the current
* timezone from the Locale preferences. These exist only under
* AmigaDOS 2.1 and up, but it is probably correctly set on more
* Amigas than the TZ environment variable is. We check that
* only if TZ is not validly set. We do not parse daylight
* savings syntax except to check for presence vs. absence of a
* DST part; United States rules are assumed. This is better
* than the tzset()s in the Amiga compilers' libraries do.
* 15 Jan 96, Chr. Spieler, corrected the logic when to select low level
* sendpkt() (when FileDate(), Agetch() or windowheight() is used),
* and AMIGA's Agetch() (CRYPT, and UnZip(SFX)'s UzpMorePause()).
* 10 Feb 96, Paul Kienitz, re-fiddled that selection logic again, moved
* stuff around for clarity.
* 16 Mar 96, Paul Kienitz, created a replacement localtime() to go with the
* new tzset(), because Aztec's is hopelessly broken. Also
* gmtime(), which localtime() calls.
* 12 Apr 96, Paul Kienitz, daylight savings was being handled incorrectly.
* 21 Apr 96, Paul Kienitz, had to replace time() as well, Aztec's returns
* local time instead of GMT. That's why their localtime() was bad,
* because it assumed time_t was already local, and gmtime() was
* the one that checked TZ.
* 23 Apr 96, Chr. Spieler, deactivated time() replacement for UnZip stuff.
* Currently, the UnZip sources do not make use of time() (and do
* not supply the working mktime() replacement, either!).
* 29 Apr 96, Paul Kienitz, created a replacement getenv() out of code that
* was previously embedded in tzset(), for reliable global test
* of whether TZ is set or not.
* 19 Jun 96, Haidinger Walter, re-adapted for current SAS/C compiler.
* 7 Jul 96, Paul Kienitz, smoothed together compiler-related changes.
* 4 Feb 97, Haidinger Walter, added set_TZ() for SAS/C.
* 23 Apr 97, Paul Kienitz, corrected Unix->Amiga DST error by adding
* mkgmtime() so localtime() could be used.
* 28 Apr 97, Christian Spieler, deactivated mkgmtime() definition for ZIP;
* the Zip sources supply this function as part of util.c.
* 24 May 97, Haidinger Walter, added time_lib support for SAS/C and moved
* set_TZ() to time_lib.c.
* 12 Jul 97, Paul Kienitz, adapted time_lib stuff for Aztec.
* 26 Jul 97, Chr. Spieler, old mkgmtime() fixed (ydays[] def, sign vs unsign).
* 30 Dec 97, Haidinger Walter, adaptation for SAS/C using z-stat.h functions.
* 19 Feb 98, Haidinger Walter, removed alloc_remember, more SAS.C fixes.
* 23 Apr 98, Chr. Spieler, removed mkgmtime(), changed FileDate to convert to
* Amiga file-time directly.
* 24 Apr 98, Paul Kienitz, clip Unix dates earlier than 1978 in FileDate().
* 02 Sep 98, Paul Kienitz, C. Spieler, always include zip.h to get a defined
* header inclusion sequence that resolves all header dependencies.
* 06 Jun 00, Paul Kienitz, removed time_lib.c due to its incompatible license,
* moved set_TZ() back here, replaced minimal tzset() and localtime()
* with new versions derived from GNU glibc source. Gave locale_TZ()
* reasonable European defaults for daylight savings.
* 17 Jun 00, Paul Kienitz, threw out GNU code because of objections to the GPL
* virus, replaced with similar functions based on the public domain
* timezone code at ftp://elsie.nci.nih.gov/pub. As with the GNU
* stuff, support for timezone files and leap seconds was removed.
* 23 Aug 00, Paul Kienitz, moved timezone code out from here into separate
* platform-independent module 'timezone.c'.
* 31 Dec 00, Christian Spieler, moved system-specific timezone help funcions
* back in here, from 'timezone.c'.
* 07 Jan 01, Paul Kienitz, Chr. Spieler, added missing #include "timezone.h"
* and "symbolic" preprocessor constants for time calculations.
* 15 Jan 02, Paul Kienitz, excluded all time handling code from compilation
* for Zip utilities (when "defined(UTIL)")

/* DESCRIPTION
* This routine chooses between 2 methods to set the file date on AMIGA.
* Since AmigaDOS 2.x came out, SetFileDate() was available in ROM (v.36
* and higher). Under AmigaDOS 1.3.x (less than v.36 ROM), SetFileDate()
* must be accomplished by constructing a message packet and sending it
* to the file system handler of the file to be stamped.
*
* The system's ROM version is extracted from the external system Library
* base.
*
* NOTE: although argument passing conforms with utime(), note the
* following differences:
* - Return value is boolean success/failure.
* - If a structure or array is passed, only the first value
* is used, which *may* correspond to date accessed and not
* date modified.

; flate.a created by Paul Kienitz, 20 June 94. Last modified 30 Dec 2005.
;
; 68000 assembly language version of inflate_codes(), for Amiga. Prototype:
;
; int inflate_codes(__GPRO__ struct huft *tl, struct huft *td,
; unsigned bl, unsigned bd);
;
; Where __GPRO__ expands to "Uz_Globs *G," if REENTRANT is defined,
; otherwise to nothing. In the latter case G is a global variable.
;
; Define AZTEC to use the Aztec C macro version of getc() instead of the
; library getc() with FUNZIP. AZTEC is ignored if FUNZIP is not defined.
;
; Define NO_CHECK_EOF to not use the fancy paranoid version of NEEDBITS --
; this is equivalent to removing the #define CHECK_EOF from inflate.c.
;
; Define INT16 if ints are short, otherwise it assumes ints are long.
;
; Define USE_DEFLATE64 if we're supporting Deflate64 decompression.
;
; Do NOT define WSIZE; it is always 32K or 64K depending on USE_DEFLATE64.
; You also do not need to define FUNZIP or SFX, if you create t:G_offs.a
; correctly (see below).
;
; ------
;
; The following include file is generated from globals.h just before this
; is compiled, and gives us equates that give the offsets in Uz_Globs of
; the fields we use, which are:
; ulg bb
; unsigned int bk, wp
; (either array of unsigned char, or pointer to unsigned char) redirslide
; For regular UnZip but not fUnZip:
; int incnt, mem_mode
; uch *inptr
; For fUnZip:
; FILE *in
; It also defines a value SIZEOF_slide, which tells us whether the appropriate
; slide field in G (either area.Slide or redirect_pointer) is a pointer or an
; array instance. It is 4 in the former case and a large value in the latter.
; Lastly, this include will define CRYPT as 1 if appropriate and supply flag
; definitions for major compile options that may affect the layout of the
; globals structure and the functionality of the core decompression routines
; (currently FUNZIP, SFX, REENTRANT, DLL, NO_SLIDE_REDIR, USE_DEFLATE64).
INCLUDE "t:G_offs.a"
; struct huft is defined as follows:
;
; struct huft {
; uch e; /* number of extra bits or operation */
; uch b; /* number of bits in this code or subcode */
; union {
; ush n; /* literal, length base, or distance base */
; struct huft *t; /* pointer to next level of table */
; } v;
; }; /* sizeof(struct huft) == 6, or 8 if padded */
;
; The G_offs include defines offsets h_e, h_b, h_v_n, and h_v_t in this
; struct, plus SIZEOF_huft.

# Set the processor to generate code for UnZip and fUnZip. Specify one of:
# ANY 68000 68010 68020 68030 68040 68060 (Default: ANY or 68000)
# Use of the assembly versions is not supported yet since some of the asm
# source file do not assemble with 68000 instructions.
# Any help is appreciated of course.
CUSECPU = ANY
# Uncomment both CUTIL and LUTIL to make use of utility.library of OS 2.04+
# The utility.library is *not* used for UnZipSFX to ensure maximum portability
# between the different Amiga systems (minimal config: 68000 and OS 1.2).
# You can change this by adding the $(LUTIL) macro in the UnZipSFX linking
# rules (See below: Final output targets, UnZipSFX:).
# WARNINGS when using the utility library:
# 1. All Executables will *only* work with AmigaDOS 2.04 (v37) or higher.
# 2. You *need not* compile/link with short-integers using the
# utility.library. It will crash your machine. See Libraries below.
#
# Default: commented (not used)
#
#CUTIL = UTILLIB DEFINE=_UTILLIB
#LUTIL = WITH SC:LIB/utillib.with # include necessary linker defines
# Choose one stack-handling method (default=faster)
# StackExtend: Dynamic runtime stack extension. You won't notice stack overflows.
# StackCheck: On a stack overflow a requester appears which allows you to exit.
# Note that either stack watching will slow down your executable because of the
# extra code run on each function entry. On the other hand, you won't crash
# anymore due to stack overflows. However, you should not have *any* stack
# problems with info-zip if you raise your stack to 20000 (which I'd
# recommend as a minimum default stack for all applications) or more using the
# shell stack command. Type 'Stack 20000' or add it to your S:Shell-Startup.
# BTW: Typing 'Stack' prints your current stack size.
#

# Enable profiling and coverage when desired. Option COVERAGE commented

If the file didn't already exist, we created it earlier. But we just
deleted it, which we still had to do in case we are overwriting an exis-
ting file. So we must create it now, again, to set the creation time
properly. (The creation time is the best functional approximation of
the Unix mtime. Really!)
If we stored this with an AOS/VS Zip that set the extra field to contain
the ?FSTAT packet and the ACL, we should use info from the ?FSTAT call
now. Otherwise (or if that fails), we should create anyway as best we
can from the normal Zip info.
In theory, we should look through an entire series of extra fields that
might exist for the same file, but we're not going to bother. If we set
up other types of extra fields, or if other environments we run into may
add their own stuff to existing entries in Zip files, we'll have to.
Note that all the packet types for sys_fstat() are the same size & mostly
have the same structure, with some fields being unused, etc. Ditto for
sys_create(). Thus, we assume a normal one here, not a dir/cpd or device
or IPC file, & make little adjustments as necessary. We will set ACLs
later (to reduce the chance of lacking access to what we create now); note
that for links the resolution name should be stored in the ACL field (once
we get Zip recognizing links OK).

/* DGDATE
Two functions do encode/decode dates in DG system format.
Usage:
long value,year,month,day;
value=dgdate(month,day,year);
undgdate(value,&month,&day,&year); [GRR: not used in UnZip: removed]
Notes:
1. DG date functions only work on dates within the range
Jan 1, 1968 through Dec 31, 2099. I have tested these
functions through the same range with exact agreement.
For dates outside of that range, the DG system calls
may return different values than these functions.
2. dgundate() accepts values between 0 and 48213 inclusive.
These correspond to 12/31/1967 and 12/31/2099.
3. Both functions assume the data is in the native OS byte
order. So if you're reading or writing these fields from
a file that has been passed between AOS/VS and PC-DOS you
will need to swap byte order.
4. With reference to byte order, the entire range of values
supported by these functions will fit into an unsigned
short int. In most cases the input or output will be
in that variable type. You are better off casting the
value to/from unsigned short so you only need to concern
yourself with swapping two bytes instead of four.

[README/history info from Dave Lovelace]
In modifying this for use on AOS/VS, I found only a few changes
were needed for DG C 4.10:
2. There was a bug in the inflate() code, because memset()
was being called with a non-char pointer. Pretty obviously
the other systems where this was used do not have char pointers
different from other pointers. IT IS QUITE POSSIBLE THAT OTHER
BUGS OF THIS SORT EXIST. Testing did not uncover any.
3. In fileio.c, it appears that utime() is being called correctly,
but it does not set the file's time and always returns failure.
Since the AOS/VS tar and cpio programs provided by DG also suffer
from the fault of not setting file times, I must conclude that
this is by design. At any rate, I modified the code (with
compilation conditional on a macro AOS_VS) to not say "error"
when this occurs.
One change which I think would be desirable: if the filename isn't
already a relative or absolute pathname (specifying a unique location),
the program follows the searchlist under AOS/VS. It will unexpectedly
replace files anywhere in your searchlist. (If you don't use the
-o option, it will ask you first, but not tell you where the file
to be replaced resides.) I suspect this could be handled by prepending
./ to any filenames which don't already begin with /. (I haven't
checked how this would work inside the program. Po * ~" UNZIP.BCK > [UNZIP60.AOSVS]README.;1 i ssibly this
could be done in every case - I don't think PKZIP ever stores an
absolute pathname.)
To see the compile options I used, look at the file MAKE.AOS_VS.CLI
You may of course need to change the searchlist to use that macro.
------------------------------------------------------------------
15-dec-93
I fixed some of the above things, introducing new problems. It now
won't follow the searchlist - but the logic prevents it from creating
directories (if they aren't explicitly in the ZIP, anyway). But
UNZIP now sets the creation time to the time stored in the ZIP, and
ZIP now stores that instead of the TLM. I had to introduce an
extra module, with some code of my own and some other public domain
code, to accomplish this.
------------------------------------------------------------------
1-jun-94
I found an additional bug: the header was causing void to be #define'd
as int, and prototypes weren't being used. I changed UNZIP.H and
added a define of PROTO to the MAKE.AOS_VS.CLI and REMAKE.CLI macros.
I found and fixed the bug that prevented the (creation) times from
being set on files with explicit paths. (The Unix-style paths didn't
work as inputs to the AOS/VS ?CREATE system call.)
Additional known bugs:
1. I have not yet located the source of the bug that prevents the
date/time from being set (also ACLs etc.) when an existing file
is overwritten. For some reason the call to delete & recreate
the file is not being reached.
2. We need to do something in ZIP to store (as comments?) the file's
type and ACL, and then here in UNZIP extract these and apply
them. This is not going to be trivial to make foolproof, but
it's badly needed.
------------------------------------------------------------------
2-jun-94
I fixed #1 above. The compiler was checking whether UNIX was defined,
and it wasn't. It appears that *some* of the places UNIX is used are
things we can't get along with, so I changed the code to check for
AOS_VS as well. It seems to work just fine.
I also introduced a function zvs_credir() to create a directory
(as opposed to a CPD, though it can create CPDs to with the proper
file-type parameter). Directories in a path which are being created
will now be directories instead of CPDs.
The big change that's needed now is to have ZIP store (somehow)
the file's ACL and file type, and then to have UNZIP use this
information to recreate the file as it was before ZIPping. Ideally,
ZIP should also store links and CPD max-block info as well. Planned
strategy: either in the name field but after the name, or in a comment,
store the packet returned by ?FSTAT (using sys_fstat()), and then
use this packet for the ?CREATE call in zvs_create().
------------------------------------------------------------------
22-Jul-94
The changes to use the extra-field field for AOS/VS file info are in
place. In general, if a ZIPfile was created with the current rev of
ZIP.PR, the files should be restored with file type, ACL, etc. OK.
I didn't test to make sure element size & max index levels come
through OK, but I think they should.
Unix symbolic links are now UNZIPped OK, but ZIP.PR isn't yet able
to ZIP links. When it is, UNZIP should be ready.
In general UNZIP now ignores the searchlist fairly well, but not
perfectly. If the directory of a file you're UNZIPping can be
referenced elsewhere in the searchlist, UNZIP will find the file
there. (For example, if the file UDD/BBASIC/ZZPGSUBSET.SR is in
the ZIPfile, and : is in your searchlist, then UDD and UDD:BBASIC
will be created under your current directory, but UNZIP will still
find :UDD:BBASIC:ZZPGSUBSET.SR instead of =UDD:BBASIC:ZZPGSUBSET.SR.
Filenames (which are now stored in uppercase by ZIP.PR) must be
matched exactly if specified. This applies to Unix path structure
as well as case.
------------------------------------------------------------------
4-Aug-94
I fixed a bug which caused (for links only) the Unix pathname to
be put through ux_to_vs_name twice. The result was that a path
such as dir1/dir2/fname went first to :dir1:dir2:fname and
then to dir1?dir2?fname.
I also added the /NOSEA switch to the cc/link lines in the macros
MAKE.AOS_VS.CLI and REMAKE.CLI. This should prevent any confusion
over whether a file exists somewhere other than relative to the current
dir. This would disable calls to system() from using the searchlist,
but in this program I think they're all useless & hopefully inactive
anyway.

atari.c
Atari-specific routines for use with Info-ZIP's UnZip 5.1 and later.
Contains: readdir()
do_wild() <-- generic enough to put in fileio.c?
mapattr()
mapname()
checkdir()
mkdir()
close_outfile()
stamp_file() [optional feature]
version()
Due to the amazing MiNT library being very, very close to BSD unix's
library, I'm using the unix.c as a base for this. Note: If you're not
going to compile this with the MiNT libraries (for GNU C, Turbo C, Pure C,
Lattice C, or Heat & Serve C), you're going to be in for some nasty work.
Most of the modifications in this file were made by Chris Herborth
(cherborth@semprini.waterloo-rdp.on.ca) and /should/ be marked with [cjh].

# Makefile for UnZip, UnZipSFX and fUnZip: Atari ("real" makes only)
# Version: 5.53 25 December 2006
#==============================================================================
# INSTRUCTIONS (such as they are):
#
# "make" -- makes UnZip on a generic Atari
#
# CF are flags for the C compiler. LF are flags for the loader. LF2 are more
# flags for the loader, if th ey need to be at the end of the line instead of at
# the beginning (for example, some libraries). FL and FL2 are the corre-
# sponding flags for fUnZip. LOCAL_UNZIP is an environment variable that can
# be used to add default C flags to your compile without editing the Makefile
# (e.g., -DDEBUG_STRUC, or -FPi87 on PCs using Microsoft C).
#
# Be sure to test your new UnZip (and UnZipSFX and fUnZip); successful compila-
# tion does not always imply a working program.

# Makefile for UnZip, UnZipSFX and fUnZip: Atari ST Chris Herborth
# Version: UnZip 5.20+, MiNT, GNU C 25 December 2006

# Based on the original unix Makefile and modified by Chris Herborth
# (cherborth@semprini.waterloo-rdp.on.ca), Nov.13/93.
# Be sure to test your new UnZip (and UnZipSFX and fUnZip); successful com-
# pilation does not always imply a working program.

Here it is... the UnZip 5.1 port for the Atari ST/TT/Falcon!
This took me longer than I expected thanks to a difference between the
MiNT library and most UNIX libraries... symlinks are 0x16000
instead of 0xa000... I'm told this isn't even defined in POSIX, so I
can't really complain. At least we've got a filesystem that can use
symlinks!
This port requires GNU C and allows you to build an unzip/zipinfo/funzip
that supports long filenames (on appropriate filesystems, thanks to the
MiNT library), as well as symlinks. It also does "proper" (ie, DOS-style)
translation of text-file end-of-line characters. The programs also build
as shared-text binaries, so you can start unzipping several files at once
in the background and only a small part of unzip will be duplicated in
memory.
I build unzip with the MiNT library, GNU C 2.5.8 (2.5.7 and lower have a
rather sever problem in the optimiser that affects 68000 code only; it
adds 68020-only instructions to the 68000 code). Oh, and I tested it
extensively under MiNT's minix filesystem as well as the bogus DOS
filesystem that "normal" Atari partitions have.
The Makefile won't need any editing if you want to built unzip et al. on
a minix filesystem; if you want to install it on a DOS filesystem, use
"cp" instead of "ln" for zipinfo. [Or, to save disk space, make a script/
command-file which invokes "unzip -Z ...". --CN] This is such a good
idea that I'm annoyed that Greg thought of it and I didn't... ;-) If
you're using a shell worth your while, you can alias zipinfo to
'unzip -Z' and then forget all about this paragraph.
If you want to compile this using Turbo C (aka Pure C in North America)
you're on your own... That's ok, I'll make a nice binary version of
unzip available as soon as the official 5.1 version is released (give or
take a few days).
Enjoy! Cave Newt should be given kudos for keeping this monster easy to
port... ;-) [Hah! But thanks anyway. :-) --CN]
PLEASE email me to tell me if you've uploaded the source or binary
versions of Unzip 5.x to any BBS systems or commercial online systems so
we can update the WHERE file!

conventions of the file attribute data are different...)
'At' - signature
ef_size - size of data in this EF (little-endian unsigned short)
full_size - uncompressed data size (little-endian unsigned long)
flag - flags (byte)

data - compressed or uncompressed file attribute data
If flag & EB_BE_FL_UNCMPR, the data is not compressed; this optimisation is
necessary to prevent wasted space for files with small attributes. In this
case, there should be (ef_size - EB_BEOS_HLEN) bytes of data, and full_size
should equal (ef_size - EB_BEOS_HLEN).
If the data is compressed, there will be (ef_size - EB_BEOS_HLEN) bytes of
compressed data, and full_size bytes of uncompressed data.
If a file has absolutely no attributes, there will not be a 'At' extra field.
The uncompressed data is arranged like this:
attr_name\0 - C string
struct attr_info (fields in little-endian format)
attr_data (length in attr_info.ai_size)

This port is based on both BeOS and UNIX versions.
As BeOS version it can extract specific file attributes.
TODO
----
There is only one thing to be fixed:
write_attr() should return count of bytes written. However that's a bug
related with AFS only.
Please report any bugs to Zip-Bugs@lists.wku.edu.
If this bug related with AtheOS/Syllable only, you can mail me directly:

If flag & EB_BE_FL_UNCMPR, the data is not compressed; this optimisation is
necessary to prevent wasted space for files with small attributes (which
appears to be quite common on the Advanced Access DR9 release). In this
case, there should be ( ef_size - EB_BEOS_HLEN ) bytes of data, and full_size
should equal ( ef_size - EB_BEOS_HLEN ).
If the data is compressed, there will be ( ef_size - EB_BEOS_HLEN ) bytes of
compressed data, and full_size bytes of uncompressed data.
If a file has absolutely no attributes, there will not be a 'Be' extra field.
The uncompressed data is arranged like this:
attr_name\0 - C string
struct attr_info (fields in big-endian format)
attr_data (length in attr_info.size)

# Makefile for Info-ZIP's unzip, unzipsfx, and funzip on BeOS
#
# Copyright (c) 1998-2006 Info-ZIP
# Chris Herborth (chrish@qnx.com)
#
# This is the new New and Improved Makefile for BeOS; it will:
#
# 1) automatically detect your platform (PowerPC or x86) if none is
# specified; the default compiler is CodeWarrior for PowerPC, or
# gcc for x86
#
# 2) let you cross-compile for the other platform (PowerPC or x86), in
# theory
#
# 3) let you use Metrowerks CodeWarrior (default) or GNU C to build with
# for either platfor, in theory
#
# To choose a specific architecture, define the ARCH environment
# variable on the make command-line:
#
# ARCH=what make -f beos/Makefile
#
# where "what" can be "powerpc" or "x86".
#
# To choose a specific compiler, define the CC environment variable on
# the make command-line:
#
# CC=compiler make -f beos/Makefile
#
# where "compiler" can be "mwcc" or "x86".
#
# Of course, you can combine these two:
#
# ARCH=powerpc CC=mwcc make -f beos/Makefile
#
# or:
#
# CC=gcc ARCH=x86 make -f beos/Makefile
#
# To automatically install the fresh new unzip, use the "install" target:
#
# make -f beos/Makefile install

* [UNZIP60.BEOS]README.;1 + , i . / 4 < @ - Z 0 1 2 3 K P W O 5 6 q 7 q 8 9 G H J UnZip 5.4 for BeOS
NOTE:
If you want to build UnZip 5.4 or later from the source, you'll need to
have the "xres" tool installed (unless you remove the "xres" lines in the
beos/Makefile). This will cease to be a problem when BeOS R4 ships this
fall. Until then, you can get xres from
ftp://ftp.be.com/pub/experimental/tools/xres-102.zip.
HISTORY
UnZip 5.30 was the first official release of Info-ZIP's UnZip to support
the filesystem in BeOS.
UnZip 5.31 added support for the new filesystem that appeared i L 5 UNZIP.BCK i Z [UNZIP60.BEOS]README.;1
n the
Advanced Access Preview (aka DR9) Release of BeOS.
UnZip 5.32 added several important bug fixes.
UnZip 5.4:
- supports BeOS on x86 hardware (and cross-compiling, if a compiler is
present)
- ask the Registrar to assign a file type to files that don't have one
- adds a new -J option on BeOS; this lets you extract the data for a file
without restoring its file attributes (handy if you stumble on really
old BeOS ZIP archives... from before BeOS Preview Release)
- will restore attributes properly on symbolic links (you'll need
zip 2.21 or later to create ZIP files that store attributes for
symbolic links)
*** WARNING ***
You may find some extremely old BeOS zip archives that store their
file attributes differently; these will be from DR8 and earlier (when
BeOS copied the MacOS type/creator fields instead of using the current
extremely flexible scheme).
You can still unpack the _data_ in older zip files, but you won't be
able to recover the file attributes in those archives. Use the -J option
with these files or you'll get "compressed EA data missing" and "zipfile
probably corrupt" errors, even though the data is intact!
The new scheme makes handling BeOS file attributes much more robust, and
allows for possible future expansion without another round of
incompatibilities.
That's life on the edge!
*** WARNING ***
The new filesystem allows for huge files (up to several terabytes!) with
huge amounts of meta-data (up to several terabytes!). The existing ZIP
format was designed when this much data on a personal computer was
science fiction; as a result, it's quite possible that large amounts of file
attributes (more than maybe 100+K bytes) could be truncated. Zip and UnZip
try to deal with this in a fairly sensible way, working on the assumption
that the data in the file is more important than the data in the file
attributes.
One way to run into this problem is to mount an HFS volume and zip
some Mac files that have large resources attached to them. This
happens more often than you'd expect; I've seen several 0-byte files that
had over four megabytes of resources. Even more stupid, these resources
were _data_ (sound for a game), and could have been easily stored as
data...
