I have gotten error 77 and error 2 while compiling gcc following the linux from scratch directions.

With any LFS query give the book version, page reference on the same line as the title, usually. The host system is also helpful

That's a show stopper. it does a compile of basically nothing, just to check the compiler is there. It isn't. Loop back to the early chapter pages & check your work. You got something wrong. Without knowing what chapter you're in, I can't be more precise.

Ok - thanks for that.

In chapter 5, it's using your host system's compiler. But that process is breaking down somewhere. IIRC, is does a basic check that your system can create an executable, and yours is failing that. Have you gcc? In the path? Set up for compiling and see if cc points to it.

Did you check config.log as suggested? Look at the end of that file and you might find further information to give us.

I fixed this issue. I ended up chowning everything and trying to delete and reinstall gcc but to no avail. As for how I fixed it I'm not really sure. I got frustrated and reinstalled the whole OS again but now it won't go on the second pass which I'll probably post after I finish writing this.

Sometimes that's fastest. Mark this solved, and put it down to learning.
