[Mingw-users] MinGW linker cmdline parser broken

[Oliver L. <bl...@bl...>]

Howdy,

I'm having trouble compiling a GTK application for Win32 using
MinGW under MSys. While the compiler commands work fine, the
following link command causes trouble:

gcc -Wall `pkg-config --libs gtk+-2.0 gthread-2.0` -o MyPrg.exe 
src/main.o src/app.o src/cpu.o src/io.o src/str.o src/sys.o

output:
   undefined reference to g_printf
   undefined reference to g_object_unref
   ... and so on

When i just modify the order of args in the command like this:

gcc -o MyPrg.exe src/main.o src/app.o src/cpu.o src/io.o src/str.o 
src/sys.o -Wall `pkg-config --libs gtk+-2.0 gthread-2.0`

...then linking works fine.

The matter is, i have to put '-o MyPrg.exe' and especially all object
filenames at the beginning of the command line, followed by all other
options...

This problem ain't easy to circumvent because the linker commands
in question are generated by either autotools or SCons, both causing
the same trouble.

I've tried this with gcc-core-3.4.5 as well as gcc-part-core-4.3.0,
both with the same problem.

By the way, `pkg-config --libs gtk+-2.0 gthread-2.0` is resolved to:

-LE:/MSYS_GTK/1.0/lib -lgtk-win32-2.0 -lgdk-win32-2.0 -latk-1.0 
-lgio-2.0 -lgdk_pixbuf-2.0 -lpangowin32-1.0 -lgdi32 -lpangocairo-1.0 
-lpango-1.0 -lcairo -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lglib-2.0 
-lintl

Again, compiler commands work fine, even if they contain a similar 
component like `pkg-config --cflags gtk+-2.0 gthread-2.0`. It's only
about linking.
