Re: [Ikvm-developers] undefined symbol: g_module_open

[Jim R. <jr...@er...>]

Jeroen,

I _think_ that this is a build problem.

The .so that was installed on FC8 (yum, rpm??) has this profile:

[jim@localhost mono]$ ldd /usr/lib/libikvm-native.so
         linux-gate.so.1 =>  (0x00110000)
         libgmodule-2.0.so.0 => /lib/libgmodule-2.0.so.0 (0x00116000)
         libglib-2.0.so.0 => /lib/libglib-2.0.so.0 (0x0011a000)
         libdl.so.2 => /lib/libdl.so.2 (0x001e4000)
         libpthread.so.0 => /lib/libpthread.so.0 (0x001e9000)
         libm.so.6 => /lib/libm.so.6 (0x00202000)
         libc.so.6 => /lib/libc.so.6 (0x0022b000)
         /lib/ld-linux.so.2 (0x00b93000)


the .so that is built with "nant -t:mono-1.0 classpath"
has this profile.

[jim@localhost mono]$ ldd 
/home/jim/Development/ikvm/ikvm-0.36.0.11/native/libikvm-native.so
         linux-gate.so.1 =>  (0x00110000)
         libc.so.6 => /lib/libc.so.6 (0x00117000)
         /lib/ld-linux.so.2 (0x00b93000)

without the libgmodule reference, which I think is the cause of the problem.

Any thoughts on how to fix this?

Thanks,

Jim
