Hello, quite some time ago (early 2010) I posted an issue on mantis about the linux VM's handling of files > 2GB. I don't remember whether I sent a report on the list, too, but in any case, current VMs still have the problem. IIRC, I had a half-working solution at that time, but I'm not sure what the right way is for getting this problem solved now. Could anybody please have a short look at this? It would be great if future VMs would be able to handle files of this size (many video files are bigger than that limit.)
Cheers, Hans-Martin

Hans-Martin,
The Mantis report is http://bugs.squeak.org/view.php?id=7522. I just assigned it to myself (it had previously been unassigned, sorry).
You mention that you had a half-working solution last year. Can you describe the approach or post some code if you still have it?
Thanks, Dave

I'll look up the code - I've got several half-baked VMMaker directoriey, but I think I'll be able to find it.
Thanks for looking into this!

I've looked at the files, and I think I was unsure at the time where to put the changes. There is a preprocessor define __USE_FILE_OFFSET64 , which should be defined pretty much before other linux include files will be read, so that off_t will be defined as __off64_t. I do not remember whether I tried to define that in the makefile and got problems in the make process, so I moved it into selected header or C files, or whether I directly started with the files - in any case, I think I did not get a fully working VM.
I can try to set up a working build environment with VMMaker and everything, however, I don't know whether I will have time to do that before my vacation next week.
Cheers, Hans-Martin

Thanks. I think that your vacation is the higher priority issue ;-)
I note that googling "largefile LFS gcc linux" seems to turn up some relevant explanations.
