I'm trying to build PyQt5 on Ubuntu 14.04; I've downloaded the tarball, unpacked, and run:

python configure --sip-incdir /home/chris/sip/sip-4.15.5/siplib
make

Configure finishes fine (--sip-incdir is where I installed sip), but make does't complete, with several errors such as the following:

 error: ‘SubdomainSetting’ is not a member of ‘QWebSecurityOrigin’
     QWebSecurityOrigin::SubdomainSetting a2;

(full list of errors from output on pastebin). Any ideas on how to fix are most appreciated!

I see that there is some python3-pyqt5 packages for your distribution: (http://packages.ubuntu.com/search?keywords=python3-pyqt5). Maybe simpler to install it this way.

Also, maybe you want to use the "python" command, probably calls a wrong version of python (check if you have only one version or more and if this is the version needed by pyqt5).

For example, I had to compile/install two times: one for python-2.7, and an other for python-3.4. I use PyQT5 with python-3.4 and PyQT4 with python-2.7. For call the good command python, I would use in your case: python3.4 configure.

If this doesn't work, I think there are some compatibility problems.

In this case, just check all and go back to the first step installation (from all packages needed: python, QT, and dependencies).

You'll have an easier time of it if instead of trying to build PyQt5 from the PyQt-gpl-5.2.1.tar.gz archive, you install PyQt5 version 5.2.1 (same version) directly from the Ubuntu 14.04 repositories. Open the terminal and type: 

sudo apt install python3-pyqt5

PyQt5 exposes the Qt5 API to Python 3. This package contains the following modules: QtCore, QtDBus, QtDesigner, QtGui, QtHelp, QtNetwork, QtPrintSupport, QtTest and QtWidgets.

To also install the development files for PyQt5: 

sudo apt install pyqt5-dev

Get the patched PyQt5 from http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/trusty/pyqt5/trusty/tarball/14?start_revid=14 (or with bzr branch lp:ubuntu/trusty/pyqt5), and run configure.py with Python 2.

I also had sip (python-sip-dev) installed with apt-get so I used python configure.py --sip-incdir=/usr/include/python2.7 instead.
