Hey folks,
I was wondering how the C pre-processor interfaces with make. Let's suppose
that I have a little C program, something along the lines of:
#include <stdio.h>
int
main()
{
#ifdef FOO
fprintf(stdout, "Hi, my name is foo.\n");
#endif
#ifdef BAR
fprintf(stdout, "Hi, my name is bar.\n");
#endif
fprintf(stdout, "I am always here.\n");
return(1-1);
}
It is easy to control the pre-processor in the above code by defining the
respective terms or leaving them out, however,
I am trying to control the conditionals from out of a makefile.
This is essentially the way in which the kernel sources are compiled.
Any suggestions?
Thanks
Oliver
