You can compile (and I always do) using a batch file that you basically just drop your map file onto the batch file icon and it will compile your map with the settings that you specify in the batch file.
I would first download the latest q3map2 file from the following link
http://q3map2.everyonelookbusy.net/q3map2_win32/
And then i would look at the Level Designers Reference (LDR) in teh following link.
http://simland.planetquake.gamespy.com/ldr1_1/default.htm
There is a heading on the right hand side called “Compiling Maps”, this gives a sample batch file that you could tweak to your own requirements.
The following thread may help you also.

Also there is a program that is has an interface that allows you to choose the switches you want to compile with, from link see q3map2build.

Anyway i hope this helps you out, try searching if you need anymore answers there has been lots of threads about this kind of thing.
