[Qgis-user] SAGA toolbox

[Mark Coletti]

As a follow up I am having the *exact same problems* on MacOS.  SAGA runs
from the command line without problems, yet cannot seem to run from within
qgis.  This has been an ongoing problem with qgis for the last two versions
on my machine.  Different versions, same problem.  However, I have been
(maybe?) able to resolve this issue.

This is the error dialog:

My OS:

$ uname -a
Darwin cervonepd01.geog.psu.edu 11.4.2 Darwin Kernel Version 11.4.2: Thu

The "Click here" link takes you here:
http://docs.qgis.org/2.0/en/docs/user_manual/processing/3rdParty.html

The first paragraph reads:

SAGA algorithms can be run from QGIS if you have SAGA installed in your

I can run SAGA from the command line, so that's not a problem:

$ which saga_cmd
/opt/local/bin/saga_cmd

$ saga_cmd -h

SAGA Version: 2.1.4

Further down, the same web page states:

There is no "SAGA block" in the current qgis configuration dialog that I
can see.  FWIW, I'm running qgis 2.6.1-Brighton.  There is a "SAGA"
providers option under "Processing Options," but no where to specify a
"SAGA Folder".

However, checking off the "Enable SAGA 2.0.8 compatibility" in appears to
unwedge the SAGA functionality.  (I.e., Processing -> Options and
configuration -> Providers -> Saga -> "Enable SAGA 2.0.8 compatibility") So
apparently that was the actual problem.
