Based on what you said, I was able to uninstall the higher version. I downloaded the required gcc package and saved it on my desktop. I tried to run (install) it directly, but got some error message. So, I downloaded the package and saved it to my desktop.
Then, when I installed the package - I had 365 items put on my desktop.
So, what do I do now? Can I just cut them and paste them in some folder? If so, which folder? I am not familiar with the Linux directory structure; as to which folder is meant for what functions.
Thanx again, in advance.
