Install PyQt5 to Mac OS X Yosemite with python3

install script

This snippet tested on Yosemite 10.10.1

1. Define your python3 directory (for example, "/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/")
2. Download "http://download.qt-project.org/official_releases/qt/5.3/5.3.2/qt-opensource-mac-x64-clang-5.3.2.dmg" or any other new version of qt for mac and install it.
3. Download SIP sources here: http://www.riverbankcomputing.com/software/sip/download
4. Download PyQt5-gpl sources here: http://www.riverbankcomputing.com/software/pyqt/download5
5. Go to your downloads by terminal (for example, "cd ~/Downloads")
6. tar xvf PyQt-gpl-5.3.2.tar.gz
7. tar xvf sip-4.16.4.tar.gz
8. cd sip-4.16.4/
9. python3 configure.py -d /Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3//site-packages --arch x86_64
10. make
11. sudo make install
12. sudo make clean
13. Change line "!host_build:QMAKE_MAC_SDK = macosx10.8" to "!host_build:QMAKE_MAC_SDK = macosx10.10" in ~/Qt5.3.2/5.3/clang_64/mkspecs/qdevice.pri 
14. cd ../PyQt-gpl-5.3.2/
15. python3 configure.py --destdir /Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages --qmake ~/Qt5.3.2/5.3.2/clang_64/bin/qmake
16. make
17. sudo make install
18. sudo make clean

Ok, this worked for my macOS 10.12.2 / Qt 5.80 / PyQt5.7.1 / sip 4.19 / Python3.5 installation up until step 13.

The file ~/Qt5.3.2/5.3/clang_64/mkspecs/qdevice.pri however did not contain any !host reference and simply adding it myself did not help.

Then I found this post on Stack Overflow. It stated I should run:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

which worked like a charm all the way up to step 15.

During step 15 however, I received the error:

This is the GPL version of PyQt 5.7.1 (licensed under the GNU General Public
License) for Python 3.5.3 on darwin. Error: This version of PyQt5 and the commercial version of Qt have incompatible licenses.

I was able to fix that error by commenting out some lines in PyQt5 configure.py as instructed here.

Then, I continued and the command from step 15 executed without a problem.

However, now, when I run make (step 16) I am receiving this error:

~/Downloads/PyQt5_gpl-5.7.1/QtCore/sipQtCoreQt.cpp:1093:62: error: no member named 'WindowCancelButtonHint' in namespace 'Qt'; did you mean
'WindowCloseButtonHint'?

~~~~~~^
2 errors generated.
make[1]: *** [sipQtCoreQt.o] Error 1
make: *** [sub-QtCore-make_first-ordered] Error 2

Does anyone have any idea how to fix this?

Edited the sipQtCoreQt.cpp and removed the 2 offending lines.

This worked fine on ubuntu.

This patch gave me the confidence that I wasn't totally messing up my computer.
