I was using the default one and making symlinks to gcc in /usr/local/bin because everything uses gcc to compile anyway. I'm going to go on the assumption that based on Kris' response, the programs that need to use the system gcc will be smart enough to hard code the path. How do you do tell things to use gcc3 instead of gcc? export a variable before make which tells make which compiler to use? > This way, I have gcc for the kernal, but gcc3 for access to gcc3.4 > without > clobbering the freebsd version... My big problem is that I need to remember to comment out the options in make.conf if I'm going to be doing something that needs the system compiler. > -JDB
