Ubuntu Upgrade caused flutter build to fail: Is it lstdc++ or gcc or Clang++?

Question

After routine upgrade Ubuntu, my system build failed. It is using gcc 14 now, and I guess it wants 13?

I tried following the instructions here but I don't know how to do syslink

Please give me a step by step answer of what to type.

The error-build output is below:

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:

    Change Dir: /mnt/Data/git/tipitaka-pali-reader/build/linux/x64/release/CMakeFiles/CMakeTmp

The flutter doctor is below:

I'm quite sure I need 13. It is installed and reinstalled, but not showing below:

 $ clang++ --version
    Ubuntu clang version 14.0.0-1ubuntu1
    Target: x86_64-pc-linux-gnu
    Thread model: posix
    InstalledDir: /usr/bin

The problem is the upgrade itself.. I need to be able to force it to use 13. Not sure how to do that. — Bhikkhu Subhuti, Nov 29 '22 at 08:37
Forget flutter. Can you compile a hello world c++ program with clang? — n. m. could be an AI, Nov 29 '22 at 12:39
I found the problem and solved it.. yes.. need to fix for flutter. I will post an answer. It seems there is another unlisted dependency now needed. I found the github issue. — Bhikkhu Subhuti, Nov 30 '22 at 11:06

It seems as though the new dependencies are not listed. https://github.com/flutter/flutter/issues/115909

Reinstall all dependencies (it is included here now)

sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev liblzma-dev libstdc++-12-dev
