Created attachment 5488 xfce4-mount-plugin-aarch64.patch From downstream (Fedora): Dennis Gilmore 2013-03-23 17:35:39 CET Support for the ARM 64 bit CPU architecture (aarch64) was introduced in autoconf 2.69. xfce4-mount-plugin 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/xfce4-mount-plugin/xfce4-mount-plugin-aarch64.patch which updates config.guess and config.sub to recognize aarch64.
The package depends on the Xfce-own aclocal.m4. Not so easy to upgrade, unless the xfce4-dev-tools have been upgraded. autoreconf doesn't change anything. Running Debian unstable with autoconf 2.69. The patch fails at most places. Did you try the patch versus git repository, or only versus Fedora package? I did some AC_CONFIG_DIR changes and similar stuff, maybe that helps.
Fabian, I can not test the patch and it's not mine. I have just upstreamed it and I doubt the original author of the patch can read what we are writing here cause I tried to add him into CC but his address in rhbz is unknown in this Xfce bugzilla. Maybe you can continue to comment in the downstream bug for the first steps?
