Greetings,
I have a tricky little problem I was hoping someone could
help me with. I am trying to write an Autotools macro that
extracts the value of a macro from a system header file
and defines another preprocessor macro with the same value.
Take the following short program for example.
#include <stdio.h>
int main () {
printf ("%d %d %d\n", SEEK_SET, SEEK_CUR, SEEK_END);
return (0);
}
I would like to write a Autotools macro that defines another
macro using these same values. If the program above produced:
0 1 2
I would like to define alternate names in config.h such as:
/* Define to the value of SEEK_SET from <stdio.h>. */
#define MY_SEEK_SET 0
...
Can this be done in Autotools? If so, how?
Thanks,
Eric.
