EasyC Wish List

I'm still having problems. I might not fully understand what you are suggesting.

I created a .h file of:

#ifndef LOOKUP_H
int mytable[4] = {1,2,3,4};
#endif
#ifdef LOOKUP_H
extern int mytable[];
#endif
#define LOOKUP_H

and did a file inclusion. The problem I've run across is that it must be compiled multiple times into the project. The project won't link, I get multiple defines at link time. If I put an error into the include file I get seven syntax errors. I don't know if that means it is compiled into 7 different modules or not. I could make the table static and that does link cleanly, but that means mytable[] is replicated multiple times in the system.

Our real lookup table could be a couple kbytes in size, having this replicated in the system a bunch of times might not be a good thing.

Looking for additional guidance.

Thanks,
