Hi everybody, With the 10.0 release becoming more and more tangible, I tried to switch one laptop to 10.0-BETA3 and see how it would go.
I fumbled into a problem that I have a hard time to resolve: I would like to build graphics/darktable with gcc (lang/gcc46 to be precise, through the USE_GCC system) to benefit from openmp support. Here's the problem : graphics/darktable, mostly C, uses graphics/exiv2 which is written in C++, but built with clang++/libc++. So when I try to build graphics/darktable, I get errors of unresolved symbols from exiv2 library: libdarktable.so: undefined reference to `Exiv2::XmpProperties::registerNs(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)' libdarktable.so: undefined reference to `Exiv2::XmpParser::encode(std::basic_string<char, std::char_traits<char>, std::allocator<char> >&, Exiv2::XmpData const&, unsigned short, unsigned int)' libdarktable.so: undefined reference to `Exiv2::ExifData::operator[](std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)' [...] I suppose this comes from symbol naming conventions between clang++/libc++ and g++/libstdc++ (wasn't C++ ABI supposed to be standard? I guess not). If I build exiv2 with g++, I can build darktable, but I feel this way of doing things will be a PITA in the future. Does anybody knowledgeable with gcc know how to manage those issues? -- Matthieu Volat <ma...@alkumuna.eu>
