Gotcha of the Day: Building Handbrake on CentOS

Building Handbrake on CentOS started off painlessly enough. I just followed the instructions here. But then I ran into this compilation error:

set -e; cd ./contrib/libvorbis/aotuv-b6.03_20110424/; rm -fr aclocal.m4 autom4te.cache configure; autoreconf -I m4 -fiv; CC=/usr/bin/gcc CFLAGS="" CXX=/usr/bin/g++ CXXFLAGS="" CPPFLAGS="" LDFLAGS="" PKG_CONFIG_PATH="/home/ben/util/src/HandBrake-0.9.6/build/contrib/lib/pkgconfig" ./configure --prefix=/home/ben/util/src/HandBrake-0.9.6/build/contrib/ --disable-dependency-tracking --disable-shared --enable-static --with-ogg=/home/ben/util/src/HandBrake-0.9.6/build/contrib/ HAVE_PKG_CONFIG="no"

A Google and Forum search turned up no reports of anyone else with this issue. Yet, even the latest version of the source code from SVN turned up the same issue.

The fix turned out to be as follows. I edited the file:

 ./contrib/libvorbis/module.defs

and changed:

 LIBVORBIS.CONFIGURE.bootstrap = rm -fr aclocal.m4 autom4te.cache configure; autoreconf -I m4 -fiv;

to:

LIBVORBIS.CONFIGURE.bootstrap = rm -fr aclocal.m4 autom4te.cache configure; sh autogen.sh;

(and yes, that trailing ';' is necessary)

Not sure why I'm the only one running into this. But, regardless, here's a fix.
