As the bare minimum, you'll need gcc-4 and gnu make to install libosl. lopsub is needed to build the oslfsck executable and to generate its man page. Download and install lopsub with git clone git://git.tuebingen.mpg.de/lopsub cd lopsub && make && sudo make install If everything mentioned above is available on your system, type make to build the library, the oslfsck executable and the man page. Then type make install as root to install libosl, oslfsck and the man page. Finally, update the library cache by running ldconfig The default installation prefix is /usr/local. Use make install PREFIX=/somewhere/else to install in /somewhere/else instead. The make targets in the web/ directory are used for web page generation and are not needed to compile, install or use libosl. In order to make these targets the following additional tools are needed: - [doxygen](http://www.stack.nl/~dimitri/doxygen/) - [discount](http://www.pell.portland.or.us/~orc/Code/discount/) - [ImageMagick](http://www.imagemagick.org/script/index.php) The osl logo was created with Adobe Illustrator by Sebastian Schultheiss.
