Install Qt 4.8.7 on a Mac running OS X 10.11 (El Capitan)

SGaist

Hi,

The only way I see currently is to compile Qt yourself

laseranichris

This could be a solution.

Unfortunately I am not so familiar with the OS X tool chain.

I was glad that everything is covered by Qt and QtCreator so that I could use my Windows code with slight modifications on the Mac.

The only solution for me is to compile these projects on a second OS X installation (running 10.10).

If anybody has a better idea I would be glad to hear it.

Thanks!

It really boils down to:

./configure
make -jX where X is twice the number of core you have available
sudo make install

@SGaist

Thanks, this really sounds easy.

But even for this my knowledge of OS X seems not to be sufficient....

I extracted "qt-everywhere-opensource-src-4.8.7" into /tmp.
Then I started the terminal (bash) and changed into this directory.

When I enter "./configure" I get the message:

-bash: ./configure: /bin/sh^M: bad interpreter: No such file or directory

Are there other requirements besides the installation of Xcode?

Compiling Qt is the only way I know of to get a working version of 4.X.X running on this OS.

You need to install the command line tools. You can access this from XCode or you can do a separate download.

When running 'configure' you can pass quite a number of parameters to define what you want. I suspect you don't want the examples compiled since you have been using this for a while. Run './configure -help' first to see your options. Option '-prefix' is one I always supply for example (sets the installation location).

Downloading and using the unix .tar.gz instead of the windows .zip archive would fix that problem.

Also, if you are compiling with the latest Xcode and you need Qt's openssl support, you will need to setup your own openssl since the openssl headers are not part of the SDK anymore..

Hi!

This was my mistake: I really took the Windows sources....
Sorry about this!

Using the right sources I can build Qt 4.8.7 on a Mac with OS X 10.10.5 and Xcode 7.1.

But the build still fails on OS X 10.11.1 and Xcode 7.1.
Even when I specify a different directory using "-prefix".

I decided for me that it is the best soultion to have a second installation running OS X 10.10 and use the Qt installer.

Thank you for you comments.

What errors do you get ?

@SGaist

These are the errors I get:

painting/qpaintengine_mac.cpp:345:19: error: use of undeclared identifier 'CMGetProfileByAVID'
CMError err = CMGetProfileByAVID((CMDisplayIDType)displayID, &displayProfile);
^
painting/qpaintengine_mac.cpp:348:9: error: use of undeclared identifier 'CMCloseProfile'
CMCloseProfile(displayProfile);

Why twice?

SGaist

Ok, so it's an API that's not available anymore on El Capitan. You can use the patch homebrew is using to compile Qt.

So keeps all cores busy, if you need them for something else, just use less cores than what you have available.

I'm encountering the same problem as laseranichris, then I tried the patch. But then I got another error:
...
Undefined symbols for architecture x86_64:
"Phonon::ObjectDescriptionModel<(Phonon::ObjectDescriptionType)0>::qt_metacast(char const*)", referenced from:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
...

How can I fix this? Thank you very much!

SGaist

Did you restart your build from scratch ?

sandy.martel23

@DoHuuVi

just configure with "-nomake examples"

DoHuuVi

@SGaist : yes, I retried from scratch but still encountered the error.

I'm trying with nomake example.

SGaist

Did you apply the patch I linked to ?

@SGaist
Thanks so much for your reply.
I didn't try the patch. I am new to this, and could you please tell me more detail about how to apply it?

Hi
I think you just need to change the
src/gui/painting/qpaintengine_mac.cpp
file
All in red are deleted and this line is inserted:
CGColorSpaceRef colorSpace = CGDisplayCopyColorSpace(displayID);

in the function
QCoreGraphicsPaintEngine::macDisplayColorSpace

There is a tool to apply patches but in this case
"1 file changed, 1 insertion(+), 7 deletions(-)"
Seems ok to apply by hand.
