[O-MPI devel] tar file name length limit

[Ralf Wildenhues]

>From a recent ChangeLog entry:
| Part 1 of 2 of a commit to reduce filenames in the romio component
| (because we kept bumping up against the max filename limit in "tar"
| when making tarballs, especially if the version number got long).

If you can allow to limit developers to Automake >= 1.9, you should be
able to use longer file names by selecting a different tar format than
tar-v7, e.g., tar-pax or tar-ustar.  Automake docs suggest that ustar
should be widely usable, in contrast to the rather recent but POSIX pax
format.  ustar does not have the length limit.
If you want to stick to tar-v7, you might want to check out the
"filename-length-max=99" Automake option to tell you about long names
right away.

Cheers,
Ralf

I committed a variant of this -- thanks!

I did not yet increase the required version of Libtool -- see my next 
mail about this.

I have no objections to this...  :-)


how's this? (I spent waaay to much time learning obscure shell stuff 
for

this)

I allows me to do
ACLOCAL='aclocal -I /usr/local/share/aclocal' ./autogen.sh

and it works a little better.. waiting for a build now.

You beat me to it! :)

If you want to be even more obscure, you can replace these three lines
with this single line:
 : ${ACLOCAL=aclocal}
