Well, the non-presence of a library isn't necessarily a fatal error. Anyway, it's of course better to first keep going to potentially emit further error messages, in this case the unresolved symbols. > [...] > The fact that your object file is ".obj" instead of ".o" would indicate > that it's built with a Microsoft Compiler - so, if need be, you should > be able to build the requisite ".lib" file from the dll using your > Microsoft Compiler installation's lib tool (as Bill has hinted). The 'error LNK2019' certainly comes from a M$ compiler (more precisely, its linker). You can also use GNU Binutils' 'dlltool' to create M$-compatible import libraries (*.LIB). -leif -- You received this message because you are subscribed to the Google Groups "mpir-devel" group.
