LFS question...

LFS question...

[James Kelty]

I'm trying to get over the 2Gig file size Limit on my RedHat 7.3 system.
I've found some sites talking about the LFS api, but it seems that I
have to actually compile my progs with a few different C flags to get it
to work properly.

Does anyone know of an 'overall' solution to this problem, rather than
having to recompile?

Sorry, I meant RedHat 7.2 with kernel version 2.4.7

That is also what I thought, but I am running ext3, but I would think
that issue would also be taken care of. Hmmmm. Ok. Weird. My RH 7.3
system running ext3 does NOT have this problem, but it IS running kernel
2.4.18. Hmmm.

Ok, thanks anyway!

Hi James,

> Sorry, I meant RedHat 7.2 with kernel version 2.4.7

Someone please correct me if I am wrong, but it is my understanding that
ext2 and 2.4 no longer suffer from the 2Gig file size limit ?

 Course that doesn't help you James, if you are not running ext2.

A number of standard Unix API functions accept and/or return file
offsets (e.g. lseek, mmap). On a 32-bit system, these offsets (type
off_t) are 32-bit signed integers, which are limited to +/- 2Gb.

If a program needs work with files which are larger than 2Gb, it has
to use the extended functions (e.g. lseek64, mmap64), and store
offsets using a (64-bit) off64_t.

There isn't any way that you take an executable than uses 32 bits for
a file offset and "magically" make it use 64 bits.
