Compiling SourceMod Plugins
Ok, so you've read the Introduction to SourcePawn and Introduction to SourceMod Plugins and now you want to actually compile a plugin.
You'll need the compiler which is included in the .../sourcemod/scripting/ folder of the main distribution (not the SDK). Windows users will need 7-zip to extract the .tar.gz files.
In Windows, open up a command prompt (Start->Run or WindowsKey+R, then "cmd"):
cd <sourcemod>\scripting spcomp myplugin.sp
In Linux use:
./compile.sh myplugin.sp
Now simply move the .smx (not .sp) file from .../sourcemod/scripting/ to the .../sourcemod/plugins/ folder.
Note: When compiling preexisting plugins it is easiest to move the included from the plugin source folder to the include folder in your Sourcemod\scripting\include. Please see Spcomp_switches specifically the -i parameter for specifying a different folder for includes.
