i have downloaded all the "how to setup xour computer for mapping" things. and i have no idea to compile my map

Well, if you're using BC, all you need to do is press the Compile button (if you've set it up correctly - there is a tutorial to that if you need help). If you're using Hammer to compile, simply press the Compile buttons, and press OK. If you're using a batch file, run it.

well i looked at the tutorial and it didnt help me

and it isnt just to push the compile button....

should i use a "specification"? which of the options do i have to choose (not the setup, the HlFix, MBA and so on.... ?

Huh? The only tools you should need to run is HLCSG, HLBSP, HLVIS and HLRAD.

i simply have NO IDEA how to compile, i try to just "compile" it but it doesnt make a bsp fil

This post has info on setting up to compile.
