Btw, did QtOpenGL module works in AmyCygnix setup ?

Maybe still some help except testing we can do ?

#include <proto/exec.h>
#include <devices/timer.h>
#include <stdio.h>

int main (int argc, char **argv)

struct MsgPort *timerPort = IExec->CreatePort (NULL, 0L);
uint32 timerSignalMask = (1 << timerPort->mp_SigBit);
struct TimeRequest *timerRequest = (struct TimeRequest *) IExec->CreateIORequest (timerPort, sizeof (struct TimeRequest));

IExec->OpenDevice (TIMERNAME, UNIT_MICROHZ, (struct IORequest *)timerRequest, 0L);

//set timeval and start IO
timerRequest->Time.Seconds = 10;
timerRequest->Time.Microseconds = 0;
IExec->SendIO ((struct IORequest *)timerRequest);

//await result
IExec->WaitPort (timerPort);
printf("timeout!\n");

//close timer.device

IExec->DeleteIORequest ((struct IORequest *)timerRequest);

(can you imagine going at the QT Developer Day showing off an Amiga?!?!?!?)

Is there anything in 4.7 that makes its port easier than 4.6.2?
