Switching C++ Compilers with xbps-alternatives

[ghost]

System

• c++ --version:
  c++ (GCC) 9.2.0
  Copyright (C) 2019 Free Software Foundation, Inc.
  This is free software; see the source for copying conditions. There is NO

• gcc-9.2.0_1:
  clang-9.0.0_2

Expected behavior

I would love to set the default C++ compiler to clang++ using xbps-alternatives.

Actual behavior

Trying to set alternative C++ compilers is not possible as there is no alternative group for c++.
/usr/bin/c++ is not a link and actually a regular file being part of the gcc package. There is an alternative group for cc. Many build tools like e.g. CMake use cc and c++ to compile source code.

Steps to reproduce the behavior

[jnbr]

In retrospect, the cc alternative group created more problems then it solved.
I don't think we should repeat this for c++ (even though the impact might be smaller).
Most build systems use the CXX environment variable, which, in my opinion, makes more sense then changing /usr/bin/c++.

Thanks for your reply! Ok.
