Hi,
I'm sure that this has been answered several times, but I'll ask again because couldn't find any solution by myself.
I would like to build DLL (or any other sort of library) that refers to external symbols in main application.
So far I have been able to build non-working constructs. =)

Now how I can get this working, or is it possible at all?
It's possible but you have to move "funcInMain()" into the DLL with "funcInMyLib()" or into another DLL. That's the straight-forward answer.
Yes, that one I knew already. Problem isn't actually function, in my real case it's more like having some globals that libraries should be able to read.
So let's extend this main.c a little bit:
#include <stdio.h>
/* Global that is set here and printed from DLL */ int anotherValue = 0;
/* Function in DLL */ extern void funcInMyLib(int);
void funcInMain(int i)
{
printf("funcInMain(%ld) (anotherValue=%d)\n", i, anotherValue);
}int main(int argc, char **argv)
{
antoherValue = 123;
funcInMyLib(1);
return 0;
}--------
Now, that's what I really want to do, or at least something equivalent, more portable solution. (I'm really trying to port bigger application that has plugin modules built like this.)
