I'm encountered a small problem while compiling joebot. You include a "eiface.h" with your sources which differs from the original version from the HL-SDK in one line:
your code:
Code:
void (*pfnEngineFprintf)(FILE *pfile, char *szFmt, ...);
HL-SDK (with the latest official patches!):
Code:
void (*pfnEngineFprintf) (void *pfile, char *szFmt, ...);
