Ошибка сборки Flutter Linux: cmake не может скомпилировать простую тестовую программу ⇐ C++

[Гость]

I've been developping my first flutter app using flutlab and have recently set things up in vscode. Everything works fine in the web emulator but when I try to run for linux I get the following error:

Код: Выделить всё

Launching lib/main.dart on Linux in debug mode...
CMake Error at /usr/share/cmake-3.22/Modules/CMakeTestCXXCompiler.cmake:62 (message):
The C++ compiler

"/usr/bin/clang++"

is not able to compile a simple test program.

It fails with the following output:

I've tried:
Purging and reinstalling clang --> nothing changed
Attempting to manually add the path --> can't find the right on in the myriad of search results in my file explorer, i have of course checked that libstdc++6 is installed along with the usual build-essential and g++
Now I'm not very well versed in c++ or cmake so I've been doing my best to troubleshoot but if anyone knows how to fix this it would be a lifesaver.
If there's anything else you need to know, please ask.
