Eclipse CDT "Symbol NULL could not be resolved"
c, eclipse, eclipse-cdt, mingw, windows
Solution
NULL is usually defined in stddef.h. This file is also usually included with stdlib.h and stdio.h.
And, you could always do this:
#ifndef NULL
#define NULL ((void *) 0)
#endif
Problem
I just installed `Eclipse` `CDT` with `MinGW`. All the environment variables are set, includes, etc. Tried running a hello world and everything seems to be fine. I tried loading a `C` project that I had before in my computer, it seems to load everything fine, yet I get the following error with the `NULL` symbol : ``` Symbol 'NULL' could not be resolved ``` Any insights? Thanks!
