SFML with cmake linker error? (OSX)

[imdumb]

So I'm having this problem where if I try to compile the code with cmake on my mac, it throws an error that it can't load some resources.

Code: [Select]

[100%] Linking CXX executable bird

The code works on Windows and Linux so I don't think its an issue with the code, but with how I've linked stuff.

I think the difference is in my CMakeLists.txt file. Before it was using xcode's gcc to compile (and it would not compile) and so I changed it by changing these lines.

Code: [Select]

set(CMAKE_C_COMPILER "gcc-10")
set(CMAKE_CXX_COMPILER "g++-10")
#set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
#set(CMAKE_CXX_STANDARD 11)



Any help would be appreciated!

Personally, I'd recommend sticking with Xcode/clang

The std::string ABI was changed in GCC for C++11.
So you need to make sure SFML is compiled with the same runtime than your application is.
And/or can try to enable/disable the C++11 standard for your code.
