Summary0011176: "cmake -E tar" encodes long paths such that Fedora GNU tar 1.15.1 reports errors
DescriptionForking orthogonal issue out of 0011020.

There are older versions of tar which choke on the extensions which libarchive is now using.

See e.g. http://unix.derkeiler.com/Mailing-Lists/FreeBSD/stable/2007-05/msg00700.html [^] [^]

tar outputs:
tar: Ignoring unknown extended header keyword `SCHILY.dev'
tar: Ignoring unknown extended header keyword `SCHILY.ino'
tar: Ignoring unknown extended header keyword `SCHILY.nlink'
tar: Ignoring unknown extended header keyword `LIBARCHIVE.xattr.security.selinux'

... and finally exits with code 2 (instead of just issuing a warning and exiting with 0).
Additional InformationSource for tar showing problem:

http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/7/Fedora/source/SRPMS/tar-1.15.1-26.fc7.src.rpm [^]

We're using the pax format through libarchive:

 It looks like libarchive recently discussed some changes for this:

 The upstream patch is fine as far as it goes, but we're still going to get the LIBARCHIVE extended header keyword, so tar 1.15.1 will still choke.

 FYI, CMake 'master' now supports building against a system-installed libarchive.

I managed to build from tar-1.15.1-26.fc7.src.rpm with all the patches applied and reproduced the problem:

tar: Ignoring unknown extended header keyword `SCHILY.dev'
tar: Ignoring unknown extended header keyword `SCHILY.ino'
tar: Ignoring unknown extended header keyword `SCHILY.nlink'
...
tar: Error exit delayed from previous errors

Then I built libarchive from svn trunk (r2563) and installed it to a test location. I built CMake against this version and created a tarball with a 900-character path. The above-mentioned tar extracts it correctly.

 I committed the upstream patch to CMake's libarchive:
