what qt software do I need to compile MuseScore

I'm trying to compile MuseScore on my work computer (which is a macbook pro). I installed the dev environment long ago on my home computer, but I've forgotten the details.

What part of qt do I need to install?

I found this comment on https://musescore.org/en/developers-handbook/compilation/compile-instru…
Is it still up to date?

> Qt 5.6 is shipped as a online installer, suitable for 10.7+.
> Download, open the DMG and run the online installer. By default it
> will install Qt 5.6 in your home directory.

Yes. This is up to date. Qt 5.6 is required.

I tried to compile with 5.7 and it failed. I'm not sure if it was qt related. But I'm going to take
your advise and install 5.6 and try again.

hmmm. I seem to get the same error with Qt 5.6 as with 5.7, perhaps it is not related to Qt.

Which version of Mac OSX are you using? The build process as documented is known to work on 10.10 and 10.11.
Do you have XCode installed?

jim.newton.562

• Jul 18, 2016 - 09:51

Yes Xcode is installed, but I haven't yet gotten to the point of being able to run it.
Which version of Mac OSX? It appears to be OS X El Capitan, Version 10.11.5
Is that a problem?

[DELETED] 5

• Jul 18, 2016 - 14:12

That should be fine. But do run XCode once if you never ran it on this computer..

I don't know Mac compiling, but I use 5.7 at home for testing under Windows 10 and it compiles and works.

jim.newton.562

• Jul 18, 2016 - 16:06

OK, I ran Xcode, and indeed it wanted to install a bunch of stuff, indicating to me that I had not yet run Xcode on this mac since I installed the OS some time ago. Cool.

Just to make sure I also did "git pull origin master" before recompiling.

Now when try to remake MuseScore, it claims "-- Check for working C compiler using: Xcode -- works", but the compilation still fails because of the missing gl.h file.

Here is the output:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk

Just to be 100% sure, did you install the command line tools, as quickly explained in step 3 of the developer handbook ( https://musescore.org/en/developers-handbook/compilation/compile-instru… )?
You can also try to follow this procedure to install them:
http://railsapps.github.io/xcode-command-line-tools.html
Ciao,

It indeed appears that step had been omitted.
So I went back and did it. "xcode-select --install". This claimed to be installing several things.

However, when I try to make again, I seem to advance to the next error. Do I need to set CMAKE_OSX_SYSROOT or CMAKE_OSX_DEPLOYMENT_TARGET before running make, or is the makefile supposed do do this itself?

No it should work out of the box. I'm using Cmake 3.4.1 locally (with XCode 7.3 and Mac OS 10.11.5).

I see the path /usr/local/Cellar/cmake/3.0.2, in the output. Does this mean I'm using Cmake 3.0.2? Do I need to upgrade Cmake?

i tried "brew upgrade cmake" and it did update the version apparently to 3.6.0

And now when I recompile MuseScore, I think it gets much further before failing to compile.

By any chance, is Qt 4 installed on your machine too? Maybe via brew? It could be that the Qt 4 headers are used for your compilation and you don't want that.

hmmm, good question. Do you see a clue of that in the output?

No, alas :-(

It still contains the curious DEPRECATED_SINCE errors in the compile output.
In my UNIX path I have /Users/jnewton/OpenSource/Qt/5.6/clang_64/bin.
Perhaps I should change this to /usr/local/opt/qt5/bin ???

Except if you use it somewhere else, I would remove qt from brew and use the one you installed only.

I took /Users/jnewton/OpenSource/Qt/5.6/clang_64/bin out of my UNIX path and added the newly "brew-installed" qt5, /usr/local/opt/qt5/bin.
Now make seems to be happy. My machine is getting hot and happily compiling lots and lots of stuff. This looks like it may take a while.

OK, making real progress here.
"make -f Makefile.osx release" finished successfully;
"make -f Makefile.osx install" also finished successfully;
"make -f Makefile.osx Xcode" also finished successfully.
"open build.xcode/mscore.xcodeproj" opens Xcode and starts calculating and indexing.

Looks like I'm once again a happy MuseScore developer.

Thanks for all the help.
