General / SFML 2.6.2 - MacOS

« on: Today at 12:43:19 am »

I have been trying to get sfml 2.6.2 working on my mac (m4, sequoia 15.4.1) and it always gives me the same error no matter how i try to compile it. My normal workflow (im coming from windows) is using clion. To eliminate that as the issue i tried following the tutorial on the SFML site which is with xcode, but this gives the same issue.

I always get this error

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.4.sdk/usr/include/c++/v1/string:821:42 Implicit instantiation of undefined template &#39;std::char_traits<unsigned int>&#39;
 

I have tried many things from reinstalling sfml entirely changing the compilers within cmake reinstalling xcode, reinstalling clion - all to no avail.

This is one of my CMake files which results in the same error:

cmake_minimum_required(VERSION 3.16)
project(SFMLProject)

set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)

set(CMAKE_CXX_STANDARD 17)

endif()
 

I should note this is on a project which works perfectly on windows, but cloning the repo on my mac, and updating a few things within the cmake for mac os doesnt work.

The XCode attempt is just using the default template project.

I hope i have included as much info as is needed to help debug this issue.

Many Thanks
