RH 7.3 is shipped with at least kernel 2.4.18-14 which supports LFS (Large
File Support). if you do:
[panda]$ uname -r
2.4.18-14
you should see something similiar to the above. it's still possible to
rebuild your kernel to have LFS support even if the kernel is < 2.4.x but
that's another story. if your kernel does not support LFS, Perl won't be
able to support it. if your kernel does support LFS, chances are Perl will
also support LFS. you can check to see if your Perl was built to support
LFS by:
[panda]$ perl -V | grep uselargefiles
and if you see something like 'uselargefiles=define' then you are in good
shape. finally, you also want to check if perl is built to use the LFS API:
[panda]$ perl -V | grep OFFSET_BIT
-D_GNU_SOURCE -fno-strict-aliasing -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS=64
it's highly unlikely that perl is not using the LFS API if it's capable of
handling large file. RH 7.3 and Perl that came with it, should support LFS
right out of the box.
