2GB limit problem

[Arne S. <ar...@sc...>]

I did not even try to fix the 2GB problem yet, because I have to copy the 
resulting files to my Windows98 disk anyway and we have the same file size 
limit there too (it may be a 4 GByte limit, I'm not sure).

Will the resulting binary run only on a 2.3 kernel, or will it also run on a 
2.2.x kernel (at least up to the 2 GByte limit)?

My current linux development system is a bit dated (SuSE 6.1, about two years 
old), no 64 bit functions available in that version. When my new SuSE Linux 
version shows up (the DVD version is supposed to be available mid-April), I'll 
give it a try.

My entry on http://www.freshmeat.net shows already more than 130 downloads and 
almost 900 homepage hits... cool.

Regarding the 2GB limit: current 2.3 kernels should be able to do more
(even on 32 bit machines).  In part it was also an intended limitation
in order not to break the APIs (lseek() has to be able to do relative
seeks from one end to the other).

The API issues are resolved with current glibcs.  Either use the 64
bit functions (open64, lseek64 etc.) or define _FILE_OFFSET_BITS to 64
then the standard open etc. calls will run in large file mode.
