[Mono-dev] undefined symbol: g_module_open IKVM Native Library Loading

[Jim Redman]

I was checking Mono on FC8, not on XScale, sorry for adding that confusion.

When I replace the libikvm-native.so on FC8 with one built using the 
IKVM build process, it doesn't reference gmodule and it doesn't word 
either.  So I can get a consistent failure on different platforms.

I suspect that the libikvm-native.so should reference gmodule, and the 
original library that I had on FC8, downloaded as an RPM or YUM package 
or similar DID reference it.

However, I also _suspect_ that mono should reference it, and it doesn't 
seem to even in the RPM or YUM version.  It may, and I just haven't 
found the reference, or I could be completely wrong.  I don't make any 
claim of sufficient expertise to really judge.
