Hi, The build of our C++ library (https://www.macports.org/ports.php?by=name&substr=alpscore) fails with g++-mp-6 --- apparently due to the fact that Boost libraries used by our code were compiled with the "old" pre-C++11 ABI, and g++ >=5.1 by default compiles using the "new" ABI.
I know that it is possible to compile our library with the "old" ABI by defining "_GLIBCXX_USE_CXX11_ABI=0". But this would force any code that links with our library to use the "old" ABI, too. This situation could be remedied by using Boost variant compiled with the "new" ABI --- however, there seems to be no such variant in the Boost port. The question: what is the current/recommended way to handle this "old"/"new" ABI transition? Do all C++ libraries ports that use Boost set ABI to "old"? Thank you, With best regards, Alexander. _______________________________________________ macports-dev mailing list macports-dev@lists.macosforge.org https://lists.macosforge.org/mailman/listinfo/macports-dev
