thank for your answer, but it seems like if there is no gcc pre-built on my system , cause when i do (gcc -v) ubuntu asks me to apt-get gcc, but my aim si to install it from sources, and when i try it i get this error (no acceptable C compiler found in $PATH) and when i try to find gcc on my system by (find / -name gcc) i got this directory (/usr/lib/gcc) i add it to my path, but no result. -- View this message in context: http://www.nabble.com/installing-GCC-tp22404231p22404413.html Sent from the gcc - Help mailing list archive at Nabble.com.
