Compiling AVIDemux on 64-bit Linux distro

AVIDemux is the best tool to rip DVDs, re-encode videos and edit them on the fly.

Sometimes it's a pain in the neck to compile stuff, especially on a 64-bit distro that has 32-bit compatibility libraries. Thankfully, guys at the Slamd64 forums are quite helpful in these matters.

I had an old copy of avidemux (version 2.3.0) which I worked on. I tried compiling the latest (version 2.4.1) but it requires "cmake" which I didn't have install, and didn't feel like going through the headache of finding its dependencies.

magic lines:
export LDFLAGS="-L/usr/lib64"
CFLAGS="-O2 -fPIC" ./configure --prefix=/usr \
--sysconfdir=/etc --libdir=/lib64 --includedir=/usr/include \
--with-jsapi-include=/usr/include/seamonkey-1.0.7/js/ --with-include-gettext
make -j4
make install

Without exporting LDFLAGS properly, you'll get an error like this:
/usr/lib/ could not read symbols: File in wrong format

It was picking up the 32-bit lib instead of the 64-bit one. Exporting LDFLAGS properly solved this issue.

If you get something like this:
rm -f && : -c --statistics -o cs.po
mv: cannot stat `': No such file or directory

Make sure you have this in your configure line:
