GCC 4.1 + ADFS = Crashed VRPC

Hi,

Has anyone tried using GCC with it present on an ADFS image within VRPC? Here it crashes the emulator, which in turn trashes the ADFS image.

Thanks,
Adam

P.S. Sorry, I posted this in the "programming" forum too, but got no responce so am trying here.

Can you give me an idea of exactly what you did to cause the crash?

Thanks,
Graeme

Yep.
1) I put !GCC (3.4.6R3) on my ADFS image & double-click it
2) create a test program called test/c:

Code:

#include <stdio.h>
void main(void)
{
  printf("Hello world\n");
}

3) set the CSD to the directory with the program and type gcc test.c from a task window.
4) The (virtual) machine hangs. Alt-break has no effect. Alt-enter gets me back to Windows, but choosing any of the options from "Action" menu causes it to crash and a Windows "this program has crashed" window to pop up.
5) Sometimes the ADFS image is broken and has to be fixed by DiscKnight next time I run VRPC

Everything works fine if it's on a HostFS drive.

Thanks a lot,
Adam

OK, it's not actually crashing, just making the emulator run unusably slow (ignoring the use of the Action menu items for now).

I've forwarded a fix to Aaron for distribution to beta testers. If you want to test it, please contact him via info@virtualacorn.co.uk. Note that IDE support is only present to support some older apps that assume/require the presence of an ADFS disk; I strongly suggest you stick to using a HostFS mount.

Thanks Graeme.

Unfortunately it's not possible to use HostFS for all tasks. In particular I use SVN a lot:

Further to thr above, Graeme has come up woth something else that might help.

Check the state of ADFSBuffers. It may be set to 255, setting it to zero might improve matters.

Press F12
Type: *st.
To see the status (press Shift to scroll if the output stops)
Check the state of ADFSBuffers. If not zero then:
Type : *configure ADFSBuffers 0
Then press return twice to retunt to the desktop.

Now try again, are you having the same problems?

Hi, I set adfsbuffers to 0 and the problem has gone away.

Should I keep it at 0? What other effects will that have?

Thanks,
Adam

Yes, keep the buffers set to zero. This will slow down ADFS a bit, but I doubt you will notice.

We are looking at a "better" solution to this problem.
