>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
