I'm having some (further) issues porting some Unix code to cygwin. I
have a
scenario where there are global variables defined in a shared library,
and referenced in the executable. See the example below. Yes I know
it's bad coding practice, but I'm hoping to port the code with the least
amount of re-writing as possible. It works fine under Unix, but as you
can see from below, doesn't play well under cygwin. Is there anything
I can do - apart from the obvious re-write.
Cheers,
Steve
[cdev]$ cat a.c
#include <stdio.h>
#include <stdlib.h>
extern void fx (void) ;
extern int myglobal ;
int
main (int argc, char **argv) {
myglobal = 99 ;
fx () ;
}
[cdev]$ cat b.c
#include <stdio.h>
int *myglobal ;
void
fx (void)
{
printf("here i am : myglobal = %d\n", myglobal) ;
}
[cdev]$ gcc b.c -o libb.dll -shared
[cdev]$ gcc a.c -o a -L. -lb
[cdev]$ a
