cc ?

I'm not sure which compiler suite is used on FreeBSD but it seems to me C++ compiler is not installed.

clang8 is used. cc is a C compiler, c++ is a C++ compiler.

Ok. Dunno why is not detected c++ at configure time. I'm not familiar with clang as C++ compiler, especially installed symbolic links. Please check configure output and then config.log to find why detection(tests) for C++ compiler fail. Also check detection of C complier. For instance autoconf macro should search for availability of g++ or c++ or cxx or CC and etc as C++ compiler commands.
If clang C++ is not in list detection fail.

If clang is default OS compiler is expected symbolic link c++ to clang++ or similar. May be some OS setup commands could set such links.

At end ./configure --help outputs environment variables .
Those variables could be used to tune build process.
For instance CXX=my-c++ ./configure ... could be used to change C++ compiler.
