Autotools defaults to the 'v7' legacy tar format in GNU tar, through passing of the '-o' parameter to GNU tar. Enabling this option results in errors for users with 32 bit UIDs. For example, with the Open vSwitch package:
$ make dist
...
tardir=openvswitch-2.3.90 && ${TAR-tar} chof - "$tardir" | GZIP=--best gzip -c >openvswitch-2.3.90.tar.gz
tar: value 12345678 out of uid_t range 0..2097151
tar: Exiting with failure status due to previous errors
make[1]: Leaving directory `/development/ovs'
...
I managed to modify the Autoconf 'configure.ac' file to use the 'tar-ustar' format, which allow longer file names and other niceties. Again, with the Open vSwitch package:
diff --git a/configure.ac b/configure.ac
index ebb8b02..6505189 100644
--- a/configure.ac

This would appear to be an issue that would affect all users with 32 bit UIDs who wish to use the 'dist' target and its derivatives. Given this information, is modifying the 'configure.ac' file like above this the best approach to fix this issues? It fixes the issue but it would require modifying the 'configure.ac' file of all packages that use GNU Autotools. Perhaps there's some other way to enable this at runtime (i.e. './configure --enable-tar-ustar')?
Kind regards,
Stephen
PS: I have researched the mailing list, Google, and the source in my F20 machine for an answer to this question. Sadly, I did not find one.
