Seems like I should have checked that bug tracker first...
I've tried several other things, including installing the fonts manually in the Mac OS font library, getting those QFontDatabase lines out, trying to bypass QFontDatabase etc, but it does not seem to work or I don't know enough of it. Perhaps the best thing is to wait until a second beta of Qt 4.5.0 comes out, and hope that it's resolved there. In the meantime I'll ask a friend of mine who had more experience with Qt whether he has some idea. Some pressure on the Qt guys to repair that bug might help too, I'd like to avoid digging into the Qt source myself.

I'm not a mac user :) but I wonder : the bug affects Leopard, the current version of Mac OSX, but loading the fonts seems to be ok for Tiger (the previous one ?). So maybe musescore does work on tiger ? Is Leopard upgrade free ? some people are still using Tiger ? and can be interested by a package for it ?
Just wondering :) Lasconic 2009/1/12 Thomas Bonte <[hidden email]>

According to http://www.qtsoftware.com/about/news/lgpl-license-option-added-to-qt , Qt 4.5 is scheduled for March 2009 and perhaps note worthy, now licensed with LGPL.

Joachim,
Any idea where we can follow up this QT issue (http://qtsoftware.com/developer/task-tracker/index_html?method=entry&id=210200)? I tried to find a few to register at the QT website, but no possibility and so very hard to track this issue. Could you ask this to your QT expert-friend? Also, do we know whether this bug has been committed already to the 4.5 trunk? I'd like to make sure it is in. Thx!

I finally got this to compile and run with the latest version! There were some steps in Joachim's procedure that have already been taken care of, so I eliminated them. As per lasconic's suggestion, I reverted all changes made in 1348. Here were the steps I took; I've added more detail to make it easier for those (like me) who don't have much programming experience.
I was running Mac OS 10.5.6 with XCode 3.1.2. 1 - Install CMake 2.6.2. (You should already have Developer Tools installed, so you don't need to install GCC when it asks you.) http://mac.softpedia.com/get/Development/Compilers/CMake.shtml 2 - Install Qt 4.4.3. (For me it got stuck for several minutes as the status bar approached the end; just let it be until it finishes.) http://mac.softpedia.com/get/Developer-Tools/Qt.shtml 3 - Download the source from the trunk: go to Finder and press Command-K. In the "Server Address" box, type https://mscore.svn.sourceforge.net/svnroot/mscore/trunk/ and press "Connect". If it prompts you for a password, keep pressing "Cancel" until it stops asking. Copy the "mscore" folder to your computer. 4 - Open Terminal (it should be in "Applications –> Utilities"), and type "cd" followed by a space. Drag the folder you just downloaded onto the terminal; this will paste the filepath onto the line. Press return. 5 - Type (or paste) "./gen-qt-projectfile . >> mscore.pro" into Terminal and press return. 6 - Make the following changes to files in the mscore folder: - file mscore/mscore/select.cpp : change "values.h" to "limits.h" - file mscore/mscore/utils.cpp : change "#ifdef __MINGW__" on line 358 to "#if defined (__MINGW32__) || defined (__APPLE__)" - file mscore/CMakeLists.txt : "set(BUILD_SCRIPT_INTERFACE FALSE)" instead of TRUE. - file mscore/mscore/CMakeLists.txt : replace three instances of "APPLE OR MINGW" with "MINGW" 7 - Repeat step 4 8 - Type (or paste) "cmake -G Xcode" into Terminal and press return. 9 - Double-click on mscore/mscore.xcodeproj (it should open in XCode) and press the "Build and Go" button. And that's it! I haven't tried doing anything with it to see if it actually works... but it did open :) Terminal gave the following warnings after CMaking: <pre> Disabling ALSA support due to OS X or MINGW build. optional package portaudio-2.0 Version 19 not found (package portaudio19-dev) </pre> It also said that Doxygen was not found, but somehow that seems unimportant (although that's a big assumption on my part). XCode gave the following build errors: • Building target "mscore" of project "mscore" with configuration "Debug" – (1 error, 4 warnings) • Running custom shell script (1 error) • Warning: No relevant classes found. No output generated |

Oops, I just realized that there are two pages of posts after the first one! This post was made after having only read the first page; now I'm reading to see what I missed :)

That's great news! Since you're also on Mac OSX 10.5, do you get the
scores properly rendered? Or do you have screenshots, because I still haven't got any further beyond the first screenshots I posted. I still don't seem to be able to get around the font trouble. I've asked a friend of mine who works as GUI developer for a company working with QT's commercial license for some help. He unfortunately told me that the Qt devs have some kind of nasty tradition of keeping bugs hanging for a long time, and advised me to hack the solution in the Qt code myself. He pointed me to the file Qt\4.4.x\src\gui\text\qfontdatabase_mac.cpp in the source, where several mac-related functionality is encoded. I've had a quick look at the file and the related functions, which are, according to his stacktrace I've been sent (windows, commercial edition, line numbers might be different): QtGuid4.dll!addFontToDatabase( ... ) Line 256 C++ QtGuid4.dll!storeFont( ... ) Line 415 + 0x2b bytes C++ gdi32.dll!77e4bcf2() [Frames below may be incorrect and/or missing, no symbols loaded for gdi32.dll] gdi32.dll!77e4bc19() QtGuid4.dll!populate_database(const QString & fam={...}) Line 464 + 0xa7 bytes C++ QtGuid4.dll!initializeDb() Line 526 + 0x22 bytes C++ QtGuid4.dll!QFontDatabase::load(const QFontPrivate * d=0x0124d9f8, int script=0) Line 1009 C++ QtGuid4.dll!QFontPrivate::engineForScript(int script=0) Line 239 + 0xd bytes C++ QtGuid4.dll!QFontMetricsF::leading() Line 1156 + 0xc bytes C++ >From initializeDb() on, these functions are mostly platformspecific. The code inside is however not for the faint of heart. I have not much experience with the mac subsystems either, let alone with their approach to fonts. Considering the huge amount of ifdefs, the guys at Apple are masters in completely rewriting whole subsystems of their OS with every new version. I'll need a large chunk of free time and loads of coffee to tackle this one. An easier way might be: if there are some TrollTech guys at Fosdem, we could corner them and friendly ask them to raise the priority level of this specific bug ;) Perhaps they hang around near the KDE track...

I've been following the os x developments with much interest. applying
the modifications posted so far (hats off to Joachim and Hypehuman), I have been able to build and run. However, the issue with the font remains. I have noticed that the when install the Mscore1-20.otf on the mac most of the characters of the font do not show. I threw together a quick program to test the font but none of the symbols in the font are accessible. It is the mscore fonts that do not show other fonts are shown when I build the code. In a new thread about fonts (fonts/noteheads) Werner indicated that the fonts are hardwired. Could this be causing an incompatibility for the mac that prevents the fonts from being shown? Just some thoughts...

Ok, I'll make sure it gets mentioned in the MuseScore presentation. Who knows there trolltech dev in the audience. http://www.fosdem.org/2009/schedule/events/musescore

Small update: today Qt 4.5.0 release candidate 1 was released. I installed it and compiled MuseScore checkout 1515 with it, but the font problem is still there... Joachim

Via http://www.qtsoftware.com/developer/preview-qt-4.5 , I found the instructions to give feedback:
My subscription for the feedback mailing list is currently waiting for approval. Obviously, it would be handy to know whether the patch at http://www.qtsoftware.com/developer/task-tracker/index_html?method=entry&id=210200 is actually applied. If so, we know the problem comes from somewhere else and we'll have to keep on digging. If not, the first step would be to be sure whether this patch will actually solve our issue.
