Mac OS X
Requirements: Intel CPU and OS X 10.6 or greater
- First install XCode Developer tools
and make sure that command line tools are installed. (Alternative to XCode:  and choose a package GCC-10.6.pkg, GCC-10.7.pkg, etc.)
When installing Jack, you want to have the 64/32 bit version.
Download and install the Jack Audio Server for OS X (after you install this you will need to restart).
http://qt-project.org/downloads Then get "Qt libraries 4.8.4 for Mac (185 MB)" and install it (takes about 5 minutes excluding download time)
Then inside the Faust directory: make sudo make install
(Ran fine on Mac Book Pro Late 2008 Intel Core 2 Duo running OS X 10.8.2 at 32 samples per frame, MacBook Pro Intel Core i7 running OS X 10.7.5 with Qt version 4.7.4 at 32 samples per frame, and iMac running OS X 10.6.8 at 32 samples per frame)
For beginners, Media:Example.ogg
sudo apt-get update
During the following, if you are prompted you should answer Yes to enable realtime process priority.
sudo apt-get install jackd1 qjackctl
sudo apt-get install libjack-dev
Then run qjackctl & and make sure that you have permission to start Jack using realtime permissions. If not, then log out and log in again and try again.
If you still don't have permission, then read the error message in the Jack Message/Status window and follow up, making sure that the appropriate entries are in /etc/security/limits.conf and/or /etc/security/limits.d/audio.conf. You may also need to add your user to the "audio" group: sudo addgroup <username> audio
On netbook, I could get it to run w/o dropouts using 64 frames/period and 8 periods/buffer. The interface was default.
On Acer laptop, I could only get it to run w/o dropouts using 96 frames/period and
sudo apt-get install libqt4-dev libqt4-core qt4-qmake
For Ubuntu precise
sudo addgroup <username> dialout
For advanced users,
Download the Faust source for version 0.9.58
Requires minimum Perl version 5.10
The following kinds of errors can for instance happen if you ever upgraded Faust but forgot to remove the older version of Faust: error: macro "max" passed 3 arguments, but takes just 2 or other particularly errors involving some standard template libraries, then please make sure you only have one version of Faust installed. You can remove all older versions of Faust by entering into each of their source directories and running sudo make uninstall (Then of course you will need to reinstall you favorite version of Faust 0.9.58 by going into its source directory and running sudo make install)
