I suspect dar is not using the large file support api for linux. 
http://www.suse.de/~aj/linux_lfs.html

I'm using standard gentoo glibc, kernel 2.6.0-test11-mm1 (not that it matters).
 Other tools on my install are abel to create files larger than 2GB.  For
example:

<0>mkennedy@killr:/space/mkennedy$ dd if=/dev/zero of=test count=3
bs=$((1024**3)) 3+0 records in
3+0 records out
0>mkennedy@killr:/space/mkennedy$ ls -l test
-rw-r--r--    1 mkennedy users    3221225472 Dec 23 20:29 test
You have new mail in /var/mail/mkennedy

Large file patch

Mkennedy,

Can you try this patch please.

thanks

Hi Chuck,

That doesn't work.  I don't think it even uses CFLAGS during the build. 

I tried revamping the ebuild a bit: 

src_compile() {
	# This seems to be necessary to get the configure script to detect
	# a 64-bit off_t type
	export CXX="g++ ${CXXFLAGS} -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE"
	export CC="gcc ${CFLAGS} -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE"
	./configure \
		--host=${CHOST} \
		--prefix=/usr \
		--infodir=/usr/share/info \
		--mandir=/usr/share/man \
		--enable-largefile \
		--enable-nodump-flag \
		--enable-examples \
		--enable-static \
		--enable-special-alloc \
		|| die "./configure failed"
#		--enable-os-bits= \
#		--enable-ea-support \
	make || die
}

During configure, off_t  is detected properly to be 64-bits (which looks promising), however when running DAR:

<0>root@killr:~/backup# ./full
./full: line 23: 10772 File size limit exceededdar --create ${BACKUP}/${NAME_FULL}-${DATE} --exclude "${NAME_FULL}-*.dar" --exclude "${NAME_DIFF}-*.dar" --exclude 'core' --noconf --empty-dir --fs-root / --no-warn ${COMPRESSION} ${EXCLUDE_COMPRESSION} ${EXCLUDE} ${SPLIT}error while testing archive: badly formed infinint or not supported format

(In this example, SPLIT='' -- ie. dont split).

dar-2.0.4.ebuild

fixed large file support on 2.0.4.
and add "ea-support" to IUSE.

Fixed in cvs, please test.

Unfortunately, the dar-2.0.4 ebuild i tested from comment #3 doesnt' fix the
problem either.  Are you folks able to reproduce this?

dar-2.0.4.ebuild

fixed and added "lfs" to IUSE.

this doesn't work either (even with the typo-correction ;-)

Anyone trying these proposed fixes?  Able to reproduce it?  Trying to ascertain if it is specific to my machine or not.  I have, however, been able to reproduce it in a chrooted environment built from stage3.

I was able to reproduce this error on my machine but I havent been able to find
a fix to it. There is a new version of dar that supposedly fixes LFS support
but I havent been able to test it because my main dev machine had died this
past week. Ill test it tonight though.

I try dar-2.0.4 without Large file patch but I got no problem on my
environment(linux-2.6.1, XFS and ext3).

# dar --version

On a recent install of Gentoo, I find that I can no longer reproduce this...
