Hello, Did you install all the dependencies? If that message shows in the "Preview" window of frescobaldi, it seems that the "python-poppler-qt4" module is not installed.
Unlike other dependencies, it's not available via macports or homebrew. You have to download it here and fellow the instructions to install it: https://code.google.com/p/python-poppler-qt4/ <https://code.google.com/p/python-poppler-qt4/> (choose the 0.16.3 version) Once unpacked on your computer, you'll have to use the Terminal to go to the python-poppler-qt4 folder and type those 2 commands: python setup.py build sudo python setup.py install Philippe -- View this message in context: http://lilypond.1069038.n5.nabble.com/frescobaldi-on-mac-tp139401p143396.html Sent from the User mailing list archive at Nabble.com. _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
