GCC on MacOS

[alexandru-andronache]

Hi,

What is the reason for GCC not being supported on mac os? I don't see it in the list of the compilers and platforms and when i try to use it even for a simple hello world program it will fail with linker errors:

[build] Undefined symbols for architecture x86_64: [build] "_std::ostream::operator<<(std::ostream& (*)(std::ostream&))", referenced from: [build] _main in main.cpp.o [build] "_std::ostream::operator<<(int)", referenced from: [build] _main in main.cpp.o [build] "_std::ios_base::Init::Init()", referenced from: [build] ___static_initialization_and_destruction_0(int, int) in main.cpp.o [build] "_std::ios_base::Init::~Init()", referenced from: [build] ___static_initialization_and_destruction_0(int, int) in main.cpp.o [build] "_std::cout", referenced from: [build] _main in main.cpp.o [build] "_std::basic_ostream<char, std::char_traits<char> >& std::endl<char, std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&)", referenced from: [build] _main in main.cpp.o [build] ld: symbol(s) not found for architecture x86_64

It's possible to get gcc to work on Mac using Cellar or Brew. We don't provide any documentation/help on how to do that though. And we support using it with our extension, but it sounds like you're hitting build issues unrelated to our extension.

I've installed gcc using brew. VS Code detects it, i can see it in the list of the compilers, but when i try to use it i get linker errors. GCC seems to be working since i can use it to compile a simple cpp file but when i try to use GCC from VS code it will not work.
If you say that this should work i will investigate more to see what is the problem.

Yeah, looks like there's some problem linking to the libstdc++ ostream library. It's working for me -- seems to load /usr/local/Cellar/gcc/10.2.0_2/lib/gcc/10/libstdc++.6.dylib (when debugging).
