mkdir to create a directory.
Don't forget to run a command in the current directory, it needs to be precceded by ./
I do think you're putting the cart before the horse somewhat though.
Also instead of emacs try pico.
Utils like pico emacs vi etc don't need the ./ but other executables do.

I had Red Hat 8 for while, it wouldn't play mp3's for me either. It said somewhere on the website it was a legal thing. There was instructions on how to sort it but they were beyond my ability at the time.

A makefile is a file that when you call it(using 'make' from the terminal in the makefile's directory), compiles all your code modules/functions at once so that they're linked together and can share code.(I think - haven't done anything with them for months and my memory's a bit sketchy )

Oh yeah I had the exact same problem as you when trying to compile C source files, GCC would detect any syntax errors with my code but then spit its dummy out when it came to compiling, just like it was half-installed. I tried for a while to get it working then gave up and switched to SuSE linux(where it worked fine).

arrr nackers, might take it into uni and try there then
thanks
