Hi , i am new to the forum , so please dont be hard on me after a problem i had in my imac and i used the installation dvd of the snow leopard system , when i tried to use gcc , or g++ in the command line of terminal Code: $ gcc -o factorial.c -bash: gcc: command not found the same thing with g++ i am not an expert of terminal but here is the thing !!! I can use gcc or g++ in xcode or in netbeans but not in the terminal command line !!! if i go to usr/bin/ i can see with the ls command g++ and gcc , so the path may be corrupted !!! 1)Is there a way to unistall gcc and g++ and then reinstall them ? 2) should i unistall xcode and eveything and reinstall them ? 3) keep in mind that because i am in university i really need at least one of both running to do my c++ tasks !!! thanks in advance !!!!
