I know what it says; I wrote it. I also know that I have virtually zero knowledge or experience with mixed 64-bit/32-bit platforms, which Linux/Amd64 is. Consequently, my guide is somewhat lacking, if only because I don't know everything. :-) I have heard that there are /lib64 directories that are searched for 64- bit libraries, but that's about it. Not having an AMD64 platform of my own, it's hard to test for anything else. So as an experiment, try writing a C program which uses that library, and compile/link with the 64-bit GCC (whatever that may be named), and run your C program. If this fails, which I suspect it will, you will know why Mono can't find your library. :-) Then, you can tell us what it takes to find the library, I can update my guide, and everyone can be happy. :-) - Jon _______________________________________________ Mono-list maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-list
