On MacOS X 10.5 and later systems, you can create libraries and
executables that work on multiple system types--known as "fat" or
"universal" binaries--by specifying multiple `-arch' options to the
compiler but only a single `-arch' option to the preprocessor. Like
this:
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \

Particular systems
==================
On HP-UX, the default C compiler is not ANSI C compatible. If GNU
CC is not installed, it is recommended to use the following options in
order to use an ANSI C compiler:
./configure CC="cc -Ae"
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
parse its `<wchar.h>' header file. The option `-nodtk' can be used as
a workaround. If GNU CC is not installed, it is therefore recommended
to try
./configure CC="cc"

./configure CC="cc -nodtk"

It works with any version of x264. However if you want better performance and interroperability, it is
highly recommended to use a modified x264 version patched with the patch mentionned here:
http://mailman.videolan.org/pipermail/x264-devel/2008-April/004427.html
highly recommended to use the modified multiscling-enabled x264 available from linphone.org.
This patch enables multi-slicing, ie smaller video packets that fit into the network mtu.
It enables RFC3984 packetization-mode=0 to work.
You can download this special x264 here:
http://download.savannah.gnu.org/releases/linphone/plugins/sources/x264-snapshot-20090704-linphone-org.tar.gz
Unfortunately for bad reasons this patch hasn't been merged by x264 developpers, and no more applies with
recent versions.
So:
* compile x264-snapshot-20090704-linphone-org.tar.gz with ./configure && make && make install
* compile msx264 with ./configure --enable-hacked-x264 && make && make install

Then compile msx264 with ./configure --enable-hacked-x264 && make && make install

The multislicing feature of x264 is something that has been contributed several time, but never merged (why ?).
The linphone.org version of x264 was inspired by a patch submitted on x264-devel mailing list:
