My clang build is stuck compiling 'C' not C++ ...

[Richard S]

I added the switch -std-c++17 to my compiler switches and Android Studio complains that it's not actually building in C++, but rather C.

So what's going on here? How can I ensure that clang on Android is building in C++?

From my CMakeLists.txt file:

target_compile_options(otp PUBLIC -std=c++17 ....)

When I add that I see this pop-up in the IDE:

MyProject.app.main | debug | arm64-v8a error: invalid argument '-std=c++17' not allowed with 'C'

CMake automatically detects language through file extension. If you rename your source file to .CPP, the correct clang should get invoked.
