[View Quote] I never used the GNU C compiler, but if it can generate win code, you
should be able write bots using the sdk dll.

To avoid the problem of the incompatible LIB you can use run-time
dynamic linking (without linking the aw.lib to your prog). You're gonna
have to rewrite the header, use function pointers, and load the dll
using LoadLibrary. It's tedious, but you won't have to wait for a
specific version of the lib ;)

I compiled the following code using Borland C++ Builder and it works
fine. You could try compiling it with GNU C. Of course, you are gonna
have write the code to make it do something :)))

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>

#define AW_BUILD 5

typedef int (*pAWInit)(int);
typedef int (*pAWCreate)(char*, int, void**);
typedef void (*pAWTerm)(void);
typedef int (*pAWDestroy)(void);
typedef int (*pAWWait)(int);

main (void)
{
int rc;
HINSTANCE hAWLib;
pAWInit AWInit;
pAWCreate AWCreate;
pAWTerm AWTerm;
pAWDestroy AWDestroy;
pAWWait AWWait;

hAWLib = LoadLibrary("aw.dll");

if (hAWLib != NULL) {

AWInit = (pAWInit) GetProcAddress(hAWLib, "aw_init");
AWCreate = (pAWCreate) GetProcAddress(hAWLib, "aw_create");
AWTerm = (pAWTerm) GetProcAddress(hAWLib, "aw_term");
AWDestroy = (pAWDestroy) GetProcAddress(hAWLib, "aw_destroy");
AWWait = (pAWWait) GetProcAddress(hAWLib, "aw_wait");

if (rc = (AWInit)(AW_BUILD)) {
printf ("Unable to initialize API (reason %d)\n", rc);
exit (1);
}

if (rc = (AWCreate)(0, 0, 0)) {
printf ("Unable to create bot instance (reason %d)\n", rc);
exit (1);
}

(AWWait)(1000);

(AWDestroy)();
(AWTerm)();

FreeLibrary(hAWLib);
}

printf ("seems it worked");
return 0;
}

Basically, a callback is a function pointer which is used to call a
function. Check the following code...

/* pointer to a function */
void (*afunction)(int);

/* callback installer */
void set_callback(void (*acallback)(int)) { afunction = acallback; }

/* callback caller */
void call_callback(int a) { afunction(a); }

/* function to install as a callback */
void mycallback(int a)
{
printf("a=%d\n", a);
}

void main(void)
{
set_callback(mycallback);
call_callback(1);
}

This is a generic example to show how callbacks work, too much work just
to print "a=1" :))

Using the AW SDK, you don't have to implement the "set_callback" and
"call_callback" functions. You have to write the function that will be
installed as callback using "aw_callback_set", the SDK is responsible
for calling it.

Andras, contact me, I can send you the .lib that works with BCB 3.

Declare ur callback procedure as:

procedure CitizenByName(retcode: Integer); cdecl;

I just tested it, it returns the correct citizen number and rc.

is the bot instance created correctly?
is it logged into the universe and logged into any world?
did it announce its position in the world?
