Installation of FLTK

[Note]

Note

The tar extraction directory is fltk-1.3.4 and not fltk-1.3.4-source as indicated by the tarball name.

Install FLTK by running the following commands: 

sed -i -e '/cat./d' documentation/Makefile       &&

./configure --prefix=/usr    \
            --enable-shared  &&
make

If you wish to create the API documentation, issue: 

make -C documentation html

The tests for the package are interactive. To execute the tests, run test/unittests. In addition, there are 70 other executable test programs in the test directory that can be run individually.

Now, as the root user: 

make docdir=/usr/share/doc/fltk-1.3.4 install

If desired, install some example games built as a part of the tests, extra documentation and example programs. As the root user: 

make -C test          docdir=/usr/share/doc/fltk-1.3.4 install-linux &&
make -C documentation docdir=/usr/share/doc/fltk-1.3.4 install-linux
