Hi worthnew, The SunStudio C++ ABI is not compatible with the GCC C++ ABI. One of the significant shortcomings, in my opinion, of the C++ standard (ISO/IEC 14882-1998, TR-2003) is that the standards committee did not address the C++ ABI. Although it is possible to get two different C++ compilers (or two different versions of the same C++ compiler with different ABIs) to compile, it is not a pleasant chore. Your best bet is to get your vendor to compiler their library using GCC C++ (g++). In particular, the same GCC version you are using. Anticipating your question, "What is the C++ ABI?" Look at SDN's answer for "THE C++ ABI": http://developers.sun.com/prodtech/cc/articles/CC_abi/CC_abi_content.html All those items can differ from compiler to compiler. Or even from compiler version to compiler version. One way to get two different C++ ABIs to interact is to write a "C bridge" between the two. The C bridge works because there is a standard C ABI. Having done that myself before, I can state vehemently that using a C bridge after the fact to glue to C++ systems together is unpleasant. Having a C++ implementation that uses a C API isn't so bad -- other than the nagging thought "Hey, this C API really looks object oriented... why didn't they provide a C++ API?" The reason that C++ implementation use C APIs is because the C ABI is specified, "the" C++ ABI is not. Sincerely, --Eljay
