Frecobaldi 2 Mac OS X install guide

[flup2]

Hello all,

Here is a step by step guide to install Frescobaldi on a Mac OS X system.
Frescobaldi has some known issues on a mac (see below) but after these steps
you should be able to:
- use Frescobaldi (of course)
- launch Frescobaldi with a double clickable icon
- play MIDI

* install macports (  http://www.macports.org <http://www.macports.org>   
).
Using the Terminal, run these 2 commands to update macport :

sudo port -v selfupdate

sudo port -v upgrade outdated

* Once done, it's time to install the dependencies of frescobaldi 
(depending to your computer, it may last some hours):

sudo port -v install py27-pyqt4

sudo port install poppler +quartz +qt4

* PyQt makes a link between python and qt4, but we need a library to link
those with poppler (to have the PDF preview); Frescobali's author developped
it. You have to download it here: 
https://python-poppler-qt4.googlecode.com/files/python-poppler-qt4-0.16.3.tar.gz
<https://python-poppler-qt4.googlecode.com/files/python-poppler-qt4-0.16.3.tar.gz>
  

* double click to unzip. In the Terminal you have to go to the folder where
it was unzipped (for instance cd Downloads/python-poppler-qt4-0.16.3 ).

* Run these 2 commands. The first one will compile the library, the other
one will install is. The second one needs a admin access (password will be
asked after the sudo... command)

python setup.py build

sudo python setup.py install

If you have some problems with these 2 steps, I can be necessary to specify
the complete python path:

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7/setup.py
build

sudo
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7
setup.py install

* Download Frescobaldi and place it in the Applications folder

Creation of a launcher :
-------------------------

* download the software Platypus (  http://sveinbjorn.org/software
<http://sveinbjorn.org/software>   and launch it
* choose a name in  App Name field 
* choose "Shell" in the popup "Script type"
* choose "None"  in the popup "Output"
* click "Newand paste these lines (change it according to your user name and
frescobaldi folder name) :

#!/bin/sh 

cd /Applications/frescobaldi 
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7
frescobaldi 

* show "Advanced options" and uncheck all boxes on the right, except "Runs
in background"
* you may choose a custom icon (by drag and drop)
* click "Create"

 MIDI output
-------------
Frescobaldi uses an external synthetizer that must be launched. That
synthetizer uses soundfont. If you havn't any, you may use the one included
in Musescore. (  http://musescore.org/ <http://musescore.org/>   )

* in the Terminal, install portmidi and fluidsynth :
sudo port -v install portmidi
sudo port -v install fluidsynth

* download qsynth, a mac graphical interface for fluidsynth ( 
http://sourceforge.net/projects/qsynth
<http://sourceforge.net/projects/qsynth>    )

* launch qsynth, click on "setup"
* MIDI tab; choose "CoreMidi" in the "Midi driver" popup
* Audio tab; choose "Coreaudio" in the "Audio driver" popup
* under the same tab, set "buffer size" to 256 and choose "Default for
"Audio device"
* soundfonts tab, choose a soundfont (the one included in Musescore or any
other).
* validate; in the MIDI settings of frescobaldi, click refresh MIDI ports,
et choose fluidsynth virtual port

I hope to have some time to make this easier to read (and, why not, include
it to Frescobaldi website)

Philippe
