[Qgis-developer] (Yet again) SAGA support badly broken in QGIS

[Victor Olaya]

My opinion about this (and getting stronger each time, since the
situation is getting worse...) is that we have only two solutions:

1) fork SAGA and have QGIS depend on that forked software, which we
will (in principle) not upgrade.
2) embed a fixed version of SAGA, and use only that one. SAGA should
be treated like a library: we support a given version, and not all
version of it. If you want to use a different one, you cant (just like
QGIS uses Python2 and a user cannot use Python3)

I will be happy to discuss about this.
