RE: tar, zip, gzip troubles

>>Seems to be the "non binary mounts problem".
Do you have binary mounts ?<<

Please excuse my ignorance. If binary mounts are not there by default, I
don't use them. I've seen in the FAQ that it is necessary to explicitely
mount directories if they are not on drive C: . However, I assume this
means if the dir is not on the drive where the Cygnus tools are
installed, in my case it's D:, and I've put the zip/unzip binaries in
the Cygnus/B19/i-386.../bin dir anyway.
BTW tar/gzip now works on this setup if I use it properly, as someone
else instructed me...However I'd like to have the choice between tar.gz
and zip.

This is the first I've heard of this.  "rb" and "wb" should work with
fopen(), if not it's a bug and should be reported as such.

Any others on the list seen this problem?

So what I've found advertised as ported was ported only halfways? The
author claimed that this port serves him well, but he seems to have
tweaked his Cygwin setup to support this.
Actually I tried to compile the sources on my machine with the
modifications published by the same author. Unzip made it, zip won't
link properly, but I couldn't find out what went wrong (I'll get back to
this list if I gained some more insight). At least I will play around
with unzip and make the changes you suggested.

>>PS: Newbie's, you should visit my page.<<
Done.

RE: tar, zip, gzip troubles

>>This smacks of the old binary/text problem.  It doesn't sound like you

have set your mounts (mount -b) or CYGWIN32 (binmode) variable to binary

mode so I suggest you look there first.<<

Oh yes, this cured the problem (although I had to strip the \r's from my
.bashrc to restart bash successfully). However, as Earnie Boyd pointed
out, this seems to be more a workaround than a fix and I'll try to
modify the zip/unzip sources to fix the problem (may take years,
though).
Thanks a lot

Actually the zip/unzip sources (InfoZip) compile fine with native tools
(Microsoft or Borland). You should only have to change some define or
#ifdef to get it working.

RE: tar, zip, gzip troubles

[Earnie Boyd]

This has the sounds of the all too familiar text vs binary file
processing modes.  Cygnus provided a shortcut to proper porting called
the binary mode switch stored within the mount table.  The mount
command will show this as text!=binary for text mode or text=binary
for binary mode.  This then becomes the default for the open and fopen
functions.

As I've stated on my web pages under my Personal Reflections on this
subject, IF YOU DEPEND ON THE BINARY MODE MOUNT SETTING THEN YOU ARE
MASKING A PROBLEM WHICH WILL EVENTUALLY BYTE YOU SOMEWHERE ELSE. 
Consider yourself bytten.

I suggest that you get the source code and find all of the open/fopen
statements and properly add the necessary file mode processing
switches.  The only truly way to get rid of this for good is to
properly port the code and be specific about what mode your file
should be processing in.

PORTERS OF SOFTWARE, please, don't depend on the binary mode mount
setting!!  Make the appropriate changes to the open/fopen statements.

Well, to be precise, on my homebox it's also the CDK, but at work I use

Someone else already pointed out that I should use the tar -z option

The zip/unzip problem persists, however. My setup is plain vanilla,

Re: tar, zip, gzip troubles

[jeffdb]

Sound like a text\binary problem.
Make sure the zip you have isn't setup to do auto CR\LF
conversion, and that all your directories INCLUDING /tmp
are mounted binary.

tar, zip, gzip troubles

[Dr. Markus Hönicka]

Hi,
I'm quite new to the Cygnus tools (B19), but I have some experience with
both Windows NT4 and Linux. I can unpack .tar.gz and .zip on NT and I
can create .tar.gz on Linux and create .zip on NT (WinZip, InfoZip
zip/unzip in cmd.exe). However, I can't properly pack or unpack using
the Cygnus bash. All attempts result in invalid or unreadable archives.
I've tested:
- gzip/gunzip/tar shipped with the Cygnus tools
- InfoZip zip/unzip ported to Cygnus
- InfoZip zip/unzip compiled for WinNT
The only packer that partially works is pkzip, but this fails to
recursively search subdirectories.
I've tested the whole thing on two NT boxes, and I've downloaded the
usertools twice to be sure the distribution isn't corrupted.
What am I doing wrong?
TIA
Markus

Re: tar, zip, gzip troubles

[Jan Tomasek]

Hi Markus,
(PKZIP is compatible only with itself, delete it :-)  )

I'm using tar, gzip, bzip2, info-zip, on my Win95 and Debian/Linux
without
any problem. 

I'm using tar and gzip without any problems, I unpacking with this
command: 'tar zxvf xxxx.tar.gz'

With info-zip I had probelms as you before some months. If I create zip
archive on my home computer 486-AMD running on 160MHz I wasn't able
decompress
because I was corupted. But if I create zip on my school computer (from
exactly
same files all was fine). Problem was fixed by downloading new version,
at this time I'm using (compiled for Win32 box):
	Zip 2.2 (November 3rd 1997).
It's working corecty from Command.com/bash.


Bye Jan

Hi Markus,

you may specify your setup and environment, so we can get a clue why that
happens. I had never problems with the Cygwin32 (CDK, not usertool package)
tar and gzip utils.
