No. amd64 Mono can only JIT amd64 code and only P/Invoke amd64 libraries. Mono ignores the architecture flag on assemblies, and always uses the JITter it was built against. You can never load an i386 .so with amd64 Mono. ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
Re: [Mono-dev] Error building mono on x86
Hi, I forgot to say, but I'm trying to build it as x86 on a x64 machine - the compilation as x64 worked (without the --host) Compilation on a x86 box also worked. This problem happens when I compile as x86 on a x64 box.
