Well I checked errno and it is 22 (EINVAL) So I then had a suspicion... I wrote a short native test case that would open the file on the cdrom, and just lseek to various offsets. Even running natively lseek fails past 4gb. So then, I copied the file to the hard drive. Tried it again... lseek succeeds past 4gb. So apparently the issue comes down the lseek failing with > 4 gig files only on cd-rom drives and ends up not being a wine bug after all as far as I can tell. I will try to install it from the hard drive in a little bit and see if it succeeds then. I didn't have enough time during lunch to actually let the install run from the HD. If that does work, I will at least make a note in the AppDB for supreme commander on that particular problem and see if I can submit a bug report to ubuntu for the lseek problem. Unless someone has an idea how this might be fixable via wine? If so, I'd be happy to give it a try. =) Thanks all, Stephan -----Original Message----- From: Hans Leidekker [mailto:hans(a)it.vu.nl] Sent: Tuesday, March 20, 2007 11:11 To: Stephan Rose Cc: wine-devel(a)winehq.org Subject: Re: Accessing File > 4gb problem (was: Debugging Supreme Commander) On Tuesday 20 March 2007, Stephan Rose wrote:

What is your system? What is the value of errno after the lseek call? Does calling lseek64 instead make any difference? -Hans
