I am attempting to compile an open source project in which a config.h file sets up a bunch of #defines that control whether or not other .c files in the project include certain files.
eg.
In one of the .c files
#ifdef HAVE_CONFIG_H
#include "config.h"
#endif
I have defined HAVE_CONFIG_H 1 as a user defined build setting for all configurations but it does not get seen in the .c file.
I have put a #warning "message" in the #ifdef and it does not get hit.
How do you ensure #defines are valid for all the files in a project?
I've tried including the config.h in main but it does not get included in some files because of the above #ifdef not working, and that causes other issues by the defines in the config.h not getting into the .c code.
Thx for any tips.
