Hi guys,

I'm using an MSYS + GnuWin32 environment to compile the entire Gtk suite. Works great, until I launch the Gtk configure script. The problem seems to be because of the shell but I cannot really understand why it fails in this one case and nowhere else.

I'm attaching a tiny script which fails the same way to show what happens. (well... hopefully you can reproduce the problem!) Let me know if I can help. The shell code is a bit out of my scope right now... and it probably isn't too easy to fix such a bug!

The attached file also includes the MSYS & Shell versions.

Thank you,
Alexis Wilke

    Small script which fails because it inserts a Ctrl-A in the output

     
    reproduce.sh

    Hi Earnie,

    I finally checked out this problem with version 1.0.11 and the 2006 fix to the dll (and tar/ps tools thought these have nothing to do with it.) Maybe I'm missing something?!

    I created a tarball that you can download from my ftp site here:

    ftp://ftp.m2osw.com/misc/MSYS-break.tar.bz2

    This is a large file (about 3Mb) which includes the whole test and MSYS 1.0.11. That way you can see whether I have the correct files. If you have problems downloading it, let me know and I will only put the extras I added to run my test.

    To run the test, start rxvt and then type the following:

    export PATH=/mingw/bin:/bin
    ./reproduce.sh

    I assume you won't cd anywhere, the reproduce script is in /bin.

    I did check pkg-config inside out (and I can tell you that's quite a piece of ugly code!!!) and there is no bug in pkg-config. The problem is in the handling of the variable in the shell.

    Let me know if you need more info.

    Thank you,
    Alexis

    This is still an issue. The work around is to create a script like so.

    <file name=”/mingw/bin/pkg-config”>
    <contents>
    #! /bin/sh

    echo `pkg-config.exe “$@”`
    </contents>
    </file>

    Am I missing something? I don't have time to research this, but isn't it a manifestation of the issue where command expansion with output from native (CRLF) tools substituted Ctrl-A for CR in the substitution text, when the substitution was a non-terminal substring of an enclosing quoted argument? I thought that disappeared when we moved from bash-2.x to bash-3.x
