I have done this and am sure it stuck, as previously the command gcc would not return a "gcc: no input files" and "strace gcc" offers "access("/usr/bin/gcc", X_OK) = 0" > Without seeing what you actually did to "adjust all the permissions" we > can't give you more advice than the above. I made sure that the group was set to "compiler" (a group that contains root and the user) on all instances of "cc1" and the directories that they sat within. Additionally, any "permission denied" error that I received with my strace was tracked to the file or directory, and then the permissions were adjusted with "chgrp compiler" and "chmod 750". Curiously, I've tried "chmod 777" and the files are still giving "permission denied," though root receives no such error. The owner of the files is set as root. Cheers, Christopher
