Support for the ARM 64 bit CPU architecture (aarch64) was introduced in autoconf 2.69. arts appears to use an earlier version of autoconf, preventing its being built. This can be fixed in of three ways (In order of preference): 1. Work with upstream to migrate the package to autoconf 2.69. 2. Rerun autoconf or autoreconf in %prep or %build prior to running configure. 3. Apply the patch at http://ausil.fedorapeople.org/aarch64/arts/arts-aarch64.patch which updates config.guess and config.sub to recognize aarch64.
arts.spec already runs: make -f admin/Makefile.common cvs which reruns autoconf.
Running "autoreconf -vif" creates the appropriate bits in admin/config.guess (grep aarch64 admin/config.guess) but the script does not.
Unfortunately, autoreconf is not a good solution for KDE 3 stuff because it does not collect the configure.in.in files from the subdirectories and generate the global configure.in from that, only make cvs does that. And there's also some post-processing being applied to the Makefile.in files after running automake. We already have a patch which adds --add-missing to the automake invocation, I think we need to also add --force-missing.
This should be fixed in arts-1.5.10-22.fc20: http://pkgs.fedoraproject.org/cgit/arts.git/commit/?id=a906de98e9b3c8389eed3aab40f02332c459c5c4 http://koji.fedoraproject.org/koji/buildinfo?buildID=406528 Does this work now? (If yes, I'll also build this for F19 and also apply the fix to kdewebdev (and all the other KDE 3 packages, for consistency).)
Assuming this works now. (automake --add-missing --copy --force-missing definitely does replace config.guess and config.sub with updated versions in my tests.) Also building for F19 now to make the Alpha Freeze. Closing.
