[please reply to all.]

They are mentioned, but are optional: https://gcc.gnu.org/install/prerequisites.html

This is caused by failure to compile a simple C++ program, but the cause can vary: Your system might have 
no c++ compiler (which i think is unlikely), or the existent c++ compiler rejected the program due to an 
unknown option. You can take a look at the end of config.log.
