I get an error while running mkcow:
ROOT # uml_mkcow redhat9.disk.cow redhat9.image.server-minimal.disk
Couldn't stat "/home/uml/UMLS/rh9/ROOT/redhat9.image.server-minimal.disk" :
errno = 75
Couldn't get size of backing file
'/home/uml/UMLS/rh9/ROOT/redhat9.image.server-minimal.disk', errno =
write_cow_header: Value too large for defined data type
(it's the standard RH9 image form mirrors.umlblabla.org)
Running uml_mkcow like everyone else gets me an error... I thought it means
that the file is too big an that the script can't handle it, but aren't
filesystem images always very big? I thought It would support this. I've
compiled the usermode-utilities myself, The version 20040406 files are now <
1 month old...
gcc compiler options are:
-mcpu=athlon-xp -O3 -pipe -DTUNTAP -D_LARGEFILE64_SOURCE -g -Wall
This seems to be the correct way to compile them, so I'm submitting this!
Sorry if I've missed something important, though I can't see it.
Met vriendelijke groeten,

That sure looks like it wasn't built with large file support.

That sure looks like it's building with large file support.
Are you sure you're running the mk_cow that you built?
