I've always been able to compile meson projects using clang and clang++ by running:
CC=clang CXX=clang++ meson setup clang-debug --buildtype=debug
The output I get is:
he Meson build system
Version: 1.1.0
Source dir: /home/maarten/github/psy-lib
Build dir: /home/maarten/github/psy-lib/clang-debug
Build type: native build

meson.build:1:0: ERROR: Compiler clang++ can not compile programs.
A full log can be found at /home/maarten/github/psy-lib/clang-debug/meson-logs/meson-log.txt
If I run:
meson setup debug --buildtype=debug
I get a working build, that uses cc and c++ to compile C and C++ respectively.
The relevant part from meson-log for the clang(++) build is:
-----

I think what meson tries to do is to compile the following program:
class breakCCompiler;int main(void) { return 0; }
The file (sanitycheckcpp.cc) is compiled as:
clang++ sanitycheckcpp.cc -o sanitycheckcpp.exe -D_FILE_OFFSET_BITS=64
However, it fails with the following error:
/usr/bin/ld: cannot find -lstdc++
I don't know what is going wrong. I would appreciate any help!
In short, clang++ was looking for another version of libstd++. For me the short and perhaps not optimal solution is to install another version of libstdc++
sudo apt install libstdc++-12-dev
also installing gcc version 12 might help.
I found a similar post/answer: "/usr/bin/ld: cannot find -lstdc++: No such file or directory" on running flutter linux app
