PHAT is a library of GTK+ widgets which are useful for pro-audio apps. The name is a backronym which stands for "the PHat Audio Toolkit." Installation How to build and install PHAT on your system If you're familiar with standard tarball compilation and installation procedures, then PHAT won't pose a problem for you. If you're not used to the tarball dance, you'll still probably do just fine if you follow these instructions. Apart from having a generally sane Linux distribution and build environment, you need to have GTK+-2.0 or greater installed, along with it's development files. The magic incantantations to build and install PHAT are as follows: tar -xzvpf phat.tar.gz cd phat.tar.gz ./configure make su <enter root password> make install /sbin/ldconfig Replace "phat.tar.gz" above with the actual name of the package you downloaded and you should be golden. I don't see why PHAT should fail to build on other POSIX systems such as the BSDs, but I'm not supporting it either. If and when that "I" becomes a "we," that policy may change. If you're using Windows you're probably S.O.L., but that too could change in the future (see above). Usage How to compile programs which use PHAT PHAT comes with a pkg-config .pc file, so using it is a snap. Run "man pkg-config" to learn how to make all your compilation dependcy woes disappear.
