           Summary: missing i686-pc-mingw32-pkg-config
           Product: Fedora
           Version: 11
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: medium
          Priority: low
         Component: mingw32-glib2

            Blocks: 513824
    Classification: Fedora
    Target Release: ---


(Reported here for lack of a better place).

Description of problem:
When compiling a program that uses glib, the host pkg-config program is used,
and this might cause the version numbers in the library to have a mismatch with
the mingw version of glib.

Luckily, pkg-config is a *tool*, so it is first searched prefixed with $host. 
It is enough to put this script in /usr/bin/i686-pc-mingw32-pkg-config then:

  #! /bin/sh
  prefix=`i686-pc-mingw32-gcc --print-sysroot`/mingw
  PKG_CONFIG_PATH=$PKG_CONFIG_PATH${PKG_CONFIG_PATH:+:}$prefix/lib/pkgconfig
  PKG_CONFIG_PATH=$PKG_CONFIG_PATH:$prefix/share/pkgconfig
  export PKG_CONFIG_PATH
  exec pkg-config "$@"

How reproducible:
You must have the latest F11 glib (2.20.4) installed, since mingw-glib2 is
still at 2.20.1.

Steps to reproduce:
1. Add c:\mingw links as explained in bug 513819
2. Install a touch program as explained in bug 513824
3. Try configure script in bug 513819 (./configure --host=i686-pc-mingw32)

Actual result:
The script diagnoses a version mismatch

Expected result:
The script should work.

Additional info:
This bug and bug 513824, if fixed, would allow to compile glib programs without
--disable-glibtest.  Fixing bug 513819 however is enough to actually *run*
crosscompiled glib/gtk programs.

A similar bug applies to other packages with an independent -config script,
such as sdl.  That is more problematic because sdl-config is searched as a
program, not as a tool.  Still, installing i686-pc-mingw32-sdl-config would at
least allow the user to specify it manually with the SDL_CONFIG environment
variable.
