Any suggestion ?

It seems that clang has issues with the -Wextra -Wconversion flag, but I don't know if rhonabwy can do something about that.

As a workaround, you can try to disable the extra warnings in the cmake script here: https://github.com/babelouest/rhonabwy/blob/master/CMakeLists.txt#L170
