Hello.
Thank you for the prompt reply. I know my questions are kind of silly, but here isn't a person to introduce me to FreeBSD.
I am using GCC 8.0 The problem is that I have zero hours experience with FreeBSD, except the installation. Basically I do only Windows so far. Maybe the compiler is the default like you say, but I even don't know how to start it. It is completely different OS from the Windows ones.
May be I should type some command as: open GCC.exe or something like this. I just know nothing about FreeBSD. The C compilers are something I do pretty well, but only upon windows till now.
So any help would be much appreciated.
