Support for the ARM 64 bit CPU architecture (aarch64) was introduced in autoconf 2.69. nurbs++ 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/nurbs++/nurbs++-aarch64.patch which updates config.guess and config.sub to recognize aarch64.
Closing. As stated on other bug 924960, submitter did not respond to request on how to test. I do not have access to this architecture, so cannot fix.
I don't if you read this so I post it here : as pointed out in this thread : https://lists.fedoraproject.org/pipermail/devel/2013-June/184098.html The better solution is: * Added: BuildRequires: autoconf, automake, libtool, pkgconfig * In "%prep" added: autoreconf --install --force ( from https://lists.fedoraproject.org/pipermail/devel/2013-June/184111.html ) anyway I also can't test it if works because I still don't have a koji for aarch64
