Description

I tried to build qgis-2.18.13 on my Gentoo Linux box with a modified ebuild, Python3.5 and qt5 (qt4 disabled)

The build fails:

     {"Warning", T_OBJECT, offsetof(pysqlite_Connection, Warning), RO},

googling for ob_type (the first error) and python3 gives me:

Another change in the object header is that the PyObject_HEAD macro has changed so that ob_type is now in a nested structure. This means you no longer can pick the ob_type directly from the struct, so code like ob->ob_type stops working. You should replace this with Py_TYPE(ob). The Py_TYPE macro doesn’t appear until Python 2.6, so to support earlier versions we make another #ifndef:

#ifndef Py_TYPE
    #define Py_TYPE(ob) (((PyObject*)(ob))->ob_type)
#endif

from http://python3porting.com/cextensions.html

It seems to me that it is a porting to python3 issue.

Also there is a parallel make problem in linking the gui:

[ 59%] Linking CXX shared library ../../output/lib64/libqgis_gui.so

Running with the build with -j1 as MAKEOPTS the build process goes further.
