[SELECT ALL] Code:
zlib.h: No such file or directory
enet/enet.h: No such file or directory
SDL.h: No such file or directory
SDL_image.h: No such file or directory
utf8.h: No such file or directory
SDL_opengl.h: No such file or directoryThese errors indicate that the files specified do not exist or have been misplaced/renamed.
[SELECT ALL] Code:
error: `GLclampf' was not declared in this scope
...And so on likely result from the fact that Code::blocks can't find the files specified in the previous errors.
[SELECT ALL] Code:
error: expected primary-expression before "const"This error is likely a direct result of not including the files that specify the GLenum, GLuint, GLsizei, etc. types. You're trying to declare a type that doesn't exist.
Habluka was dead right. If these are the errors you are getting and you can't sort them out you need to get back to learning before you try to edit something as large as AC.
On the other hand I am having a hard time rationalizing why Code::blocks can not find the files that should absolutely be there unless you have moved/renamed them. The good news is it doesn't appear to be a problem with the source or Code::blocks, just a mistake was made managing the files.
