Glib linking error: undefined reference to ...

[Christian Arnold <chrarnold web de>]

Hi,

I am not sure if this is the correct way of asking my question, but I 
nevertheless hope someone can help me... I just tried to solve the 
problem for 4 hours, and I am extremely frustrated right now... I have 
the following issue:
I installed Ubuntu 11.10 and some libraries and packages afterwards. I 
then installed glib 2.30. Everything went fine, I got no errors when 
doing ./configure, make, or make install. However, when I try to compile 
a test file in C, I can compile without errors, but I get the following  
errors:
glibTest.c:24: undefined reference to `g_timer_new'
glibTest.c:32: undefined reference to `g_random_double'
glibTest.c:36: undefined reference to `g_timer_stop'
glibTest.c:55: undefined reference to `g_str_hash'
...

I compile with:
"gcc `pkg-config --cflags --libs glib-2.0`  -g3 -O2 -std=c99 -Wall 
-pedantic glibTest.c -o glibTest
pkg-config --cflags --libs glib-2.0 gives me:
-I/usr/local/include/glib-2.0 -I/usr/local/lib/glib-2.0/include  
-L/usr/local/lib -lglib-2.0
This all worked on my old laptop with Ubuntu 10.04, and I have no idea 
what the issue is. I tried to install glib 2.28 and the newest 2.31 
version, with the same error messages. I am no real expert, so please 
try to help me and let me know as precisely as possible how I can 
address the issue, I would greatly appreciate it.
Thanks,
Christian
