I suppose I must alter gcc-related links within dirname $(which gcc).. Also, is it necessary to use the llvm-* programs rather than the system defaults when compiling using clang instead of gcc? Through long-term development and iteration, GCC, Clang, and LLVM have become mature compilers in the industry. I’ve installed gcc-4.8 using brew, setup all dependencies, headers, etc, and now CMake refuses to use gcc. You need to see how cross compiling works with gcc to … How to use the newer gcc installed by macports? not just adding them into a project's CMakeLists.txt)? Once the libraries are installed, we’ll test the build with a short demo of using Boost Filesystem. Yosys Open SYnthesis Suite. Clang is mainly used to provide performance superior to that of GCC. But when I check the 'gcc --version` it is showing older version. On macOS, is it possible and is there a benefit to use gcc 7.1 (installed via brew) instead of clang to compile Stockfish? How to use the gcc installed in macports? There is also the ability to cross compile the source code for several targets at once . Regards, Lyf g++-4.8 some_file.c or using the default gcc 4.2 by using. g++ some_file.c I want to use gcc 4.8 as the default compiler for Xcode and if I type gcc at the terminal.
