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

laseranichris

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 ?

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);
^

@SGaist said:

make -jX where X is twice the number of core you have available

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:
vtable for Phonon::ObjectDescriptionModel<(Phonon::ObjectDescriptionType)0> in window.o

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 ?

@DoHuuVi

just configure with "-nomake examples"

DoHuuVi

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

I'm trying with nomake example.

Hi,
I have tried to compile Qt 4.8.7 on Mac OS X 10.11(El Capitan)
After make -j1
I got
3 warnings and 2 errors generated.
make[2]: *** [.obj/debug-shared/qpaintengine_mac.o] Error 1
make[1]: *** [debug-all] Error 2
make: *** [sub-gui-make_default-ordered] Error 2

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.

@mrjj
Thanks a lot. After change the file, when input "sudo make -j1 install"
It runs almost half an hour. And end up with errors like this
make[3]: *** No rule to make target ../../WebCore/debug/libwebcored.a', needed by ../../../../../../lib/QtWebKit.framework/QtWebKit_debug'. Stop.
make[2]: *** [debug-install] Error 2
make[1]: *** [sub-WebKit-qt-QtWebKit-pro-install_subtargets-ordered] Error 2
make: *** [sub-webkit-install_subtargets-ordered] Error 2

SGaist

If you don't need webkit then disable its build. Also don't build as root.

@SGaist brew install qt4 works
