Hi, I've successfully installed gcc4.3.3 on my server. I write a simple hello.c,and gcc -o hello hello.c an error was encounted: gcc: error trying to exec 'cc1': execvp: no such file or directory But I can see cc1 in ..../libexec/gcc/x86_64-unknown-linux-gnu/4.3.3. It seems gcc could not find cc1. Help will be appreciated. Thanks.
