Re: [Ikvm-developers] undefined symbol: g_module_open

[Jeroen F. <je...@su...>]

Hi Jim,

Like I said, this is really outside of my area. Here's what in the nant file:

gcc -o libikvm-native.so --shared -fPIC `pkg-config --cflags gmodule-2.0` jni.c os.c

My guess is that pkg-config is returning the wrong options.

Regards,
Jeroen
