fre:ac depends on the BoCA audio component framework and the smooth Class Library. Please build and install those first.

Development packages for the following libraries need to be installed in order to build smooth, BoCA and fre:ac:

  • For the smooth Class Library: libbz2, libcurl, libfribidi, libgtk+3.0, libjpeg, libxml2
  • For the BoCA component framework: libasound2 (Linux only), libcdio, libcdio-paranoia, libexpat, liburiparser
  • For fre:ac itself: libudev (Linux only)

When the dependencies are met, run make followed by sudo make install for smooth, BoCA and fre:ac respectively.

You should then be able to run fre:ac using /usr/local/bin/freac and the command line interface using /usr/local/bin/freaccmd.
