You should only need it if you modified 'acinclude.m4' or 'configure.ac' or m4 files included by 'configure.ac'. The 'aclocal' program is part of the GNU Automake package: <http://www.gnu.org/software/automake> It also requires GNU Autoconf, GNU m4 and Perl in order to run: <http://www.gnu.org/software/autoconf> <http://www.gnu.org/software/m4/> <http://www.perl.org/> Makefile:882: recipe for target 'aclocal.m4' failed make: *** [aclocal.m4] Error 127 http://trac.webkit.org/changeset/182317/trunk/Tools/efl/jhbuild.modules was to speedup the build in case of cross compiling with qemu in ARM chroot. Previously all supported distro used automake-1.14, but the newest Ubuntu 15.10 shipped automake-1.15, that's why calling configure directly isn't enough. I propose to call autogen again for gst-plugins-bad module. It would make the build happy on older releases and on the newest Ubuntu too. The cost is a little bit slower build on the cross builders bot when we touch jhbuild.modules file.
