To install the library, run as root # make install It will copy the library to /usr/local/lib, manpages to /usr/local/man, and headers to /usr/local/include. If you want to change the prefix directory (/usr/local by default), for instance, to /home/myself/usr; just run: # make PREFIX=/home/myself/usr install This will create inside PREFIX the directories "lib", "include" and "man" if necesary, and put the required files in there. After installing, you need to run "ldconfig" in order to update your dynamic library cache. So, if you want to install to /usr (like most distro bundled software do), this is a brief command line summary: # make PREFIX=/usr install # ldconfig There are other small options that might be useful (like compiling with debugging information), you can check the Makefile for more information. If you use any BSD, or if the default "make" is not GNU make, use "gmake" instead. After installing, you're ready to use the library; you can see how by looking at the manpage with "man libfilo" If you have any question, suggestion or comment, please send it to me, Alberto Bertogli at albertogli@telpin.com.ar.
