[Mono-list] Dll loading failure

[Chris Turchin]

Hi,

I think you need to set up your LD_LIBRARY_PATH variable. I have a simple
interop sample I did with mono here:

http://turchin.net/mono/interoptest.tar.gz

that you could look at for reference (see the READM). it creates a shared
library, uses it in a c-program and also uses it via DllImport in a c#-program.

HTH.

Best Regards,

--chris
