Hi there,

I'm trying to compile some C program using glib 2.0 and i have some
trouble.

Here is my command line:
gcc -I"/usr/include/glib-2.0" -l glib-2.0 TestGLib.c

First gcc told me it didn't find glibconfig.h, that happened to be in an
awkward directory, namely
/usr/lib/glib-2.0/include/
Awkward because there was no other files in this directory and all glib
header files are in /usr/include/glib-2.0 (in particular glib/gtypes.h
that includes glibconfig.h)

So i've copied it to the proper directory (and don't ask me why it
wasn't there already).
First problem fixed.

Now my real problem is that gcc doesn't look able to manage link
edition:

----------------------------
/cygdrive/c/me/LOCALS~1/Temp/ccgMXEyg.o:TestGLib.c:(.text+0x2e):
undefined reference to `_g_int_equal'
/cygdrive/c/me/LOCALS~1/Temp/ccgMXEyg.o:TestGLib.c:(.text+0x35):
undefined reference to `_g_int_hash'
/cygdrive/c/me/LOCALS~1/Temp/ccgMXEyg.o:TestGLib.c:(.text+0x3a):
undefined reference to `_g_hash_table_new'
collect2: ld returned 1 exit status
----------------------------

It didn't find the binary code for functions that were declared in
glib.h etc.
The file "/usr/lib/libglib-2.0.a" is there though.

My version of cygwin: CYGWIN_NT-5.1

Any clues?
