[QGIS-Developer] Pb QGIS 2.18 / pyuic4

[Vincent Damoy]

Hello,

I've got problems with an old development environment, that I use to 
maintain my plugins.

I want to compile a QGIS plugin that I created myself.

I'm working with QGIS 2.18 and I've got an error with pyuic4 and a UI file :

My version of pyuic4_ : 4.12.1

*The message error**: *

Makefile:52: recipe for target 'ui_bdtravaux_sortie.py' failed
make: *** [ui_bdtravaux_sortie.py] Error 1


And *the **debug text*: (pyuic4 -d ui_bdtravaux_sortie.ui)

*************************************************

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 
'ui_bdtravaux_sortie.ui'

in <module>
     sip.setapi(api, 2)
ValueError: API 'QDate' has already been set to version 1

**************************************************


I've use my plugin for years, but I have recently changed my computer 
(and reinstalled all my development environment), and the error appeared.

I wrote to pyuic4 support, and this is their answer :

/"//This is a qgis bug. They change the API version which is unsupported 
in production code."/

Is there a way to bypass this bug with these pyuuic4 and QGIS versions?

Thanks for advance

Vincent Damoy
