CMake Error on linux (Flutter project in Android Studio)

Question

When I create a new Flutter project in Android Studio (Android Studio Electric Eel | 2022.1.1), I build an APK and run it on the android emulator with no problem, but when I try to run it on linux I get this error:

CMake Error at /usr/share/cmake-3.25/Modules/CMakeDetermineCXXCompiler.cmake:48 (message):
    Could not find compiler set in environment variable CXX:
    clang++.
Call Stack (most recent call first):
    CMakeLists.txt:3 (project)
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
Exception: Unable to generate build files

My system (Pop!_OS 22.04 LTS) doesn't have that version of CMake installed, it has /usr/share/cmake-3.22 installed

And in Android Studio settings, under System Settings -> Android SDK -> SDK Tools, CMake 3.22.1 is installed

I am not able to figure out how to adjust the CMake version in Android Studio and what is the correct solution. Please any ideas?

Answer 1

SOLVED!

In the CMakeKists.txt file (in the /linux folder) I have added at the beginning (I think it has to be before the project(runner LANGUAGES CXX) line):

set(CMAKE_CXX_COMPILER "/usr/bin/g++")

Now it runs on linux with no problems.

EDIT (best solution):

sudo apt install lib32stdc++-12-dev
