libserial: make does not work on raspbian

I copied the actual version of libserial onto my RPI3 with the actual Raspian version ( Debian GNU/Linux) and gcc etc. all updated.

“configure” works, but not the generated “Makefile”. Here is the output, which marks some problems with the option “CXX”:

Sorry, I’m not familiar enough with gcc on Linux to resolve this problem - could please anybody give me some hint? Thank you for your help!
