Installation of LibMPEG3

Install LibMPEG3 by running the following commands: 

patch -Np1 -i ../libmpeg3-1.7-makefile_mods-1.patch &&
./configure &&
make

This package does not come with a test suite.

Now, as the root user: 

make install

Command Explanations

patch -Np1 -i ...: The patch modifies the Makefile so that everything is installed with the make install command instead of just the executables being installed and manual commands used to install the library, interface headers and documentation. The patch also fixes a syntax error in the Makefile.

./configure: This is not a typical Autotools script. It is only used to check for the availability of the NASM compiler.
