BIG thanks for helping, "make CC=gcc" is working. Compilation is errorless now, but, oh no, it's the same bug I had before! Whole admin system is broken, only console works. Calling any command returns "permission denied", even !help, but I have highest admin level. Also, there's a spam in console after running a map. It says there are lot of syntax errors in custom commands. Hey, I think it's admin.dat's fault that nothing works, I'll delete custom commands and run server again, hope it will help...
(edit) Still doesn't work... Does anyone have got an idea what's going on?
P.S. What for is gamex86.dll? I think in Quake 3 you can run DLL instead of QVM, but I'm not sure.
