[PyQt] SIP API versions conflict

[Vincent Vande Vyvre]

Hi,

I've a lib written in C++ wrapped for Python with SIP.

For Python 2 no problems.

For Python 3, I've an API version conflict.

Into the configure.py I've had these lines:

import sip
print(sip, sip.SIP_VERSION_STR)

Now, I ran:
--------------------------------------------
vincent at djoliba:~/oqapy-3/trunk/lib/sip$ python3 configure.py
<module 'sip' from 
'/usr/lib/python3/dist-packages/sip.cpython-34m-x86_64-linux-gnu.so'> 4.15.5
vincent at djoliba:~/oqapy-3/trunk/lib/sip$ make

vincent at djoliba:~/oqapy-3/trunk/lib/sip$ sudo make install
[sudo] password for vincent:
cp -f oqapy_iproc.so /usr/lib/python3/dist-packages/oqapy_iproc.so
--------------------------------------------

and I try my lib:
--------------------------------------------
vincent at djoliba:~/oqapy-3/trunk/$ python3
Python 3.4.3 (default, Nov 17 2016, 01:08:31)
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
 >>> import sip
 >>> print(sip, sip.SIP_VERSION_STR)
<module 'sip' from 
'/usr/lib/python3/dist-packages/sip.cpython-34m-x86_64-linux-gnu.so'> 4.15.5
 >>> from oqapy_iproc import OqapyIProc
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
RuntimeError: the sip module implements API v11.0 but the oqapy_iproc 
module requires API v11.1
--------------------------------------------

How is it possible to have two different API's versions into the same 
module ?

I'm on Ubuntu 14.04 and I use only the version from the Ubuntu repositories.

Thanks for all advices.

Vincent
