1. I downloaded the source to /opt/gnu/gcc. 2. I unpacked them into /opt/build. 3. I changed to my object directory (/opt/build) and ran the configure with --prefix=/usr/local. 4. Finally I compiled it using make. My question is: Can I delete /opt/gnu/gcc and /opt/build once the installation process is finished? I mean, except for the loss of the GCC compiler sources, will I delete anything else important to run the compiler or the system? Tks.
