I already have the full SDK, Milkshape 3D, Hammer 3.5, Jed HL Model Viewer, Wally, SpiteWiz, SpriteView, (puff) Gensurf, Revolver, SpriteFixer and Half-Life 1.1.1.0 (I think thats the number). I want to tweak the Half-Life game for my mod but I don't have a compiler! Can anyone direct me to a free compiler download and tell me how to use it. I don't need source programs, I have Borland, but it won't compile the Microsoft 'Makefile'. Can anyone help?
