Error in `make` after `python configure.py`

Hello, I am on linux Python3.4, I am getting the following error:

Looks like the compiler can't find the Qt includes directory (there is no -I/path/to/Qt/include in the command).
My honest answer is that I have not tested this on Linux and the configure.py script does not take any special measures for this platform (unlike Windows or Mac). If you look in configure.py from line 44 onwards you will see how extra flags/paths etc. are added if you fancy fixing this yourself (pull requests gratefully received), otherwise I will spin up a Linux environment when I have time and have a go myself.
I have added the -I/<path to my Qt headers/include but I still fail in the build. I was able to fix the SIP/C++ example in PyQt4 and I have to do this in PyQt5 but I'll try to figure out.
It would be great if you can provide a minimal example for a custom QWidget minimal, with the simplest configure.py script that just shows a hardcoded example, like the original in Riverbank, that can work in linux, I haven't been able to find anybody who is fighting this.
I've updated the configure script and this example now runs successfully on Ubuntu 16.04.
Great news! I will report tomorrow on Fedora builds.
Hello, I am still getting this error on Fedora and Ubuntu:

That would suggest it can't find the SIP types...
How have you built/installed Qt/SIP/PyQt? This has been tested (on MacOS/Linux) by using the Qt installer and then building SIP and PyQt5 from source.
Tough one, I am using a virtualenv I have to check it out. What tool chain did you used when building SIP, PyQt and Qt? Something from requiremetns.txt or the official guide?
I use virtualenv too, but I don't use SIP/PyQt5 wheels via pip.
Is sip.h installed in either of these include directories:
/home/ilian/git-projects/prosfitdesktop/include/python3.4m
/usr/include/python3.4m
Yes, it's present in both directories.
Hmmm... the types that being reported as missing are defined in sip.h that is imported into sipPyMyLabelcmodule.cpp via sipAPIPyMyLabel.h. The fact that sip.h is in both directories may be causing a conflict...
You sure that I don't have to move the C++ .so files from the Qt project (src) to /usr/lib /usr/lib64 I had to do something similar for PyQt4 example from Riverbank.
Here is the makefile generated by configure.py

No need to move .so files yet, you're still compiling not linking.
Makefile looks good. I really think the issue is here is with the configuration/location (and possible duplication) of dependencies.
I just spun up a Fedora VM and everything worked fine:
- Fedora 25 Workstation
- Python 3.5.3
- Virtualenv 15.1.0 (installed via pip)
- Qt5.8 (installed via Qt web installer)
- SIP 4.19.2 (source build from here)
- PyQt5.8.2 (source build from here)
Additionally I had to install some dependencies before installing PyQt5:
sudo dnf install libGL-devel mesa-libGL-devel python3-devel
Just to ask, how did you install PyQt and SIP?
As described in my previous comment, I got the source tarballs from Riverbank and built them using a virtualenv.
