Thanks. Please let me confirm if I understood correctly. We generally have to do something with the name-space conflict (with 'extern "C"') in the mixture of C/C++. Depending on the GCC version, GCC-plugin-related libraries could be built for C or C++. So, we need to check the GCC version and choose correct one from C or C++. Am I right? -- Best Regards Masahiro Yamada
