You may have already solved the problem, but here are some extra notes to confuse^H^H^H^H^H help in the matter. P-)
I believe that sometimes you can set the environment variable (below), if for some reason it doesn't have a configure option to search in /usr/local like the --include option Alex mentioned below. export CFLAGS="-I/usr/local/include" export LDFLAGS="-L/usr/local/lib" This will help the configure script find your library. These flags will be passed and used in the compile. When you run your program, you may have to set the LD_LIBRARY_PATH variable. export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib Just a word of caution. If you you installed libx264 under the Debian package management system, and then you grabbed a more recent version elsewhere, you will want to check that your executable is not grabbing the one installed through package management. You can check this using the command ldd myexecutable Here is a good tutorial. It's mostly for creating your own libraries, but if you are the hacker type ( I assume that you are ), it will provide useful insight. http://www.yolinux.com/TUTORIALS/LibraryArchives-StaticAndDynamic.html brian On Mon, May 31, 2010 at 11:58:56AM -0700, Alex Mandel wrote: > On 05/31/2010 09:58 AM, Hai Yi wrote: > > Hello All: > > > > i've downloaded and installed libx264 from web since the one with > > ubuntu (9.10) is lower in version.
