This issue probably belongs in https://github.com/XboxDev/nxdk-libcxx

Good day!

Are you sure that your CXXFLAGS are correct and that you are compiling using at least C++ 17? Thanks!

This is the generated build command:

/opt/nxdk/bin/nxdk-cxx -D_POSIX_C_SOURCE=200809L -I/home/gleb/devilutionX/build-xbox/_deps/libfmt-src/include -std=c++20 -o CMakeFiles/fmt.dir/src/format.cc.obj -c /home/gleb/devilutionX/build-xbox/_deps/libfmt-src/src/format.cc

$ /opt/nxdk/bin/nxdk-cxx  --version
Ubuntu clang version 14.0.0-1ubuntu1

Huh, it seems like -std=c++20 should work, not sure what's up, I'm lead to believe we have a huge part of the STL, I'll try using that type on a minimal sample now too, just to make sure it's actually an issue on our end.

[kosmas12]

Just tried it too, it seems that I can't get the compiler to recognize that type either.

I've managed to fix it in XboxDev/nxdk-libcxx#8 (I have no idea what I'm doing but this seems to work)

Thanks for fixing it, a maintainer will most likely review it and merge soon
