CMake c++ library linking

Question

I have Fortran target in CMake which relies on C++ libraries. What is portable way to include STDC++ into linking?

Answer 1

If you're linking with gfortran, add -lstdc++ , if linking with g++, you'll need -lgfortran . Either way, you'll need both of them, it's just that g++ automagically links with libstdc++, and gfortran automagically links with libgfortran.

There is no "portable" way as in cross-compiler or cross-"standard library vendor", because all the libraries are named differently.

Answer 2

Theoretically the STL is part of the C++, so you don't need to do anything in CMake to use STL. On other hand: if your C++ libraries have dependencies and their have CMake module (eg: FintQt4), CMake automatically handle the linking process.
