[Qgis-user] QGIS with SAGA in macos

Tue Jun 11 08:32:51 PDT 2013

Hi all,
Some time ago, there were discussion on this list about running saga in
qgis for mac. As of today, the good news are that in master 499db4e it
seems that the saga commands run [1], however results are not as expected.
If I leave the raster as a temporary file something (ERROR 1: Writing
through VRTSourcedRasterBand is not supported) goes wrong, when I try to
the same but saving the result a python error [2] doesn't allow me to
create the desired tif.
Some saga command producing vector results run OK.
This time I was on macos 10.8.4.
Best
Agustin
