Installation of Gavl

First, fix an issue with gcc-14 and later: 

sed -i "/stdio/a #include <string.h>" src/fill_test.c

Now, Prepare Gavl by running the following commands: 

LIBS=-lm                         \
./configure --prefix=/usr        \
            --without-doxygen    \
            --with-cpuflags=none \
            --docdir=/usr/share/doc/gavl-1.4.0
make

This package does not come with a test suite.

Now Install, as the root user: 

make install

Command Explanations

LIBS=-lm: This variable ensures the math library is searched when linking.

--without-doxygen: This switch disables use of Doxygen. Omit if Doxygen is installed and you wish to build the API documentation.

--with-cpuflags=none: This switch fixes a problem identifying capabilities of the system architecture.
