Could you post the errors you get ? (only the first lines)

Also have you checked the include paths in the Makefile ? Open the "Makefile" file with notepad and check that all the include paths (which are the relative paths where the compiler will go and look for its include files) are well suited for your system. The include paths are options that begind with -I or /I (such as "-I../../metamod-1.13/metamod", which would tell the compiler that some include files it needs are located in "..\..\metamod-1.13\metamod" relatively to the current directory.)
