Try this:
==========================================================
/* dll.c */
#include <stdio.h>
extern __attribute__ ((__dllimport__)) void
exe_hello(void);
void __attribute__ ((__dllexport__))
dll_hello (void)
{
printf ("Are you there, exe?\n");
exe_hello();
}
==========================================================
/* dll.def */
LIBRARY my_dll.dll
IMPORTS
exe_hello = my_exe.exe.exe_hello
==========================================================
/* exe.c */
#include <stdio.h>
extern void __attribute__ ((dllexport))
dll_hello (void);
void __attribute__ ((dllexport))
exe_hello ()
{
printf ("Yes, the exe is here,\n");
}
int main()
{
dll_hello();
return 0;
}
==========================================================
gcc -shared -o my_dll.dll dll.def dll.c
gcc -o my_exe.exe exe.c my_dll.dll
You can do the same thing with import libs if you want, but
using a def file is much simpler.
