Could you please double check mail.jar?

I am able to list and extract the contents of mail.jar with the fastjar in GCC
3.2, 3.3 and HEAD.   Perhaps this is a darwin specific problem.

I could not reproduce it on the mainline (20030720) on powerpc-apple-darwin6.6 either:
jar --version
jar (fastjar) 0.92-gcc

Can you test it again?

I think the problem looks like apple's gcc is producing wrong code so it is miscompiling jar.
Can you rebootstrap using the 3.3 compiler you already created and try again?

i've done a clean build using the gcc build from 3.3 release. the built
(fast)jar still exhibits the same problem.

yup, same file.

are you using darwin or mac os x? could there be a difference?

Subject: Re:  fastjar error: "Error in JAR file format. zip-style comment?"

i have been experimenting a little more with this. these work:

  jar xvf mail.jar
  jar -xvf mail.jar

these don't:

  jar tvf mail.jar
  jar -tvf mail.jar

but these all do:

  jar tv <mail.jar
  jar -tv <mail.jar
  cat mail.jar | jar t

i am currently using fastjar 0.92-gcc from gcc-3.3.1 on
powerpc-apple-darwin6.6.

i can also reproduce the problem using fastjar 0.92-gcc from gcc-3.3.2
20030812 (Debian prerelease) on powerpc-unknown-linux-gnu, with exactly
the same failure pattern.

in all failure cases (darwin or linux) i have the same message.

These all work for me on the mainline on powerpc-apple-darwin6.6 so I still cannot reproduce it.
I also cannot reproduce it on 3.3.1 (20030707) on i686-pc-linux-gnu.

the code where it fails (fastjar/jartool.c:1587-1594) goes:

  #ifdef WORDS_BIGENDIAN
    tmp = L2BI(tmp);
  #endif

  if(tmp != 0x06054b50){
    fprintf(stderr, "Error in JAR file format. zip-style comment?\n");
    exit(1);
  }

i have tested the value of tmp. it is 0x504b0506. WORDS_BIGENDIAN has
not been defined, and therefore L2BI is never called (it is never
even declared). however it seems relatively clear to me that it /should/
have been called, as powerpc is a bigendian architecture.

surely the Makefile for fastjar needs to define (or not)
WORDS_BIGENDIAN, as appropriate?

> I also cannot reproduce it on 3.3.1 (20030707) on i686-pc-linux-gnu.  

as far as i know it has always worked on i386, which is a little-endian
architecture in any case.

WORDS_BIGENDIAN gets set by configure and put into config.h (at least in the mainline).

I think I know what is causing this: fastjar_AC_COMPILE_C_BIGENDIAN is not working correctly.
This is fixed on the mainline by using AC_C_BIGENDIAN_CROSS instead.
Which was this patch:
fastjar/

2002-11-22  H.J. Lu

        * acinclude.m4: Include ../config/accross.m4.
        (gcc_AC_COMPILE_CHECK_SIZEOF): Removed.
        (gcc_AC_EXAMINE_OBJECT): Removed.
        (gcc_AC_C_COMPILE_ENDIAN): Removed.
        * aclocal.m4; Rebuild.

2002-07-04  H.J. Lu

        * acinclude.m4: New.
        * configure.in: Replace AC_C_BIGENDIAN with AC_C_BIGENDIAN_CROSS.
        Replace AC_CHECK_SIZEOF with AC_COMPILE_CHECK_SIZEOF.
        * aclocal.m4; Rebuild.
        * configure: Likewise.

Since this is not a regression and it is fixed on the mainline and since libgcj was not really 
supported before 3.4 I am closing this as fixed.

I found this bug report by googling for the same error message.  In my case it
showed up on a suse9 machine.  I corrected the problem by changing my PATH
environment variable.  The broken PATH contained:

/nfs/platform/suse9/jdk1.5.0_06/jre/bin/

The corrected PATH contained

/nfs/platform/suse9/jdk1.5.0_06/bin/

Maybe this will help someone else down the road.
