Quicktime for Linux requires a copy of of libmpeg3 in a directory next to itself. This provides the mp3 interface.
Your directory structure should thus be:
/my_directory /my_directory/libmpeg3-*.*.* /my_directory/quicktime4linux-*.*.*type "make" in the libmpeg3 directory.
The makefiles automatically configure themselves. The library is in i686/libquicktime.a. You should manually set the CFLAGS environment variable with the optimum optimization parameters for your i686 derivative.
The entire source code tree should be positioned in a location where every application that needs it can access it. There is no provision for standard include files and normally it's much to difficult for users to match versions to use it as a shared library. Those of you who were born before 1997 may remember QT doing this.
