I install QGIS 2.8 in debian (linux) through nightly jessie (qgis testing) and I see that SAGA is not in processing toolbox, so I install saga gis software but still it doesn't appear in processing.

How do I run SAGA in processing toolbox?

UPDATE:

This problem is resolved through the line commands:

sudo add-apt-repository ppa:johanvdw/saga-gis

sudo apt-get update

sudo apt-get install saga

But in my case (Debian Jessie) instead of sudo add-apt-repository ppa:johanvdw/saga-gis I went to https://launchpad.net/~johanvdw/+archive/ubuntu/saga-gis and in Technical details about this PPA I choose Trusty version, copy the lines and paste in sources.list. It works!!!

  • In Processing -> Options -> Data Provider, have you activated SAGA? – AndreJ Feb 26 '15 at 17:07
  • Yes, I activate SAGA in processing options. However, it still down't appear in processing toolbox. I have SAGA installed and I test with saga_cmd command. It works. But with processing it doesn't. – Bárbara Duarte Feb 26 '15 at 17:10
  • Did you switch to the advanced view? It just looks like there is no SAGA in the simplified view. (Dropbox at the bottom of the toolbox.) – underdark♦ Feb 26 '15 at 20:09
  • Check that the box SAGA 2.0.8 compatibility is not checked. – johanvdw Mar 2 '15 at 8:43
  • I switch to the advanced view but there isn't SAGA there. The SAGA 2.0.8 compatibility box isn't in the processing options. There are only these options for SAGA: Activate (check on), Enable SAGA Import/Export optimizations, Log console output, Log execution commands. It is strange for me. – Bárbara Duarte Mar 2 '15 at 10:23

I had the same problem, but, looking on the web, I found a solution. Simply, I installed SAGA from other repository (Installing SAGA GIS 2.1).

Try the following commands from a command line:

sudo add-apt-repository ppa:johanvdw/saga-gis

sudo apt-get update

sudo apt-get install saga

I hope it works.

  • Can confirm the problem (my Debian Linux still uses v2.1.2, which is not recognized anymore by QGIS). Installing the debs from this link creates a new Processing-Provider entry for SAGA 2.1.4 – Curlew Mar 2 '15 at 15:33

For anyone else who would like to have SAGA 2.1.4 in Jessie: After jessie is released I will try to add it to backports. In the mean time, I recommend using the packages from unstable. These will work with jessie without needing to recompile. You will need to install both libsaga and saga.

I try the commands in terminal but it didn't work and I get this error (I suppose it is not correct):

  • These ppa are for ubuntu, so jessie is not known there. The ubuntu equivalent for debian jessie is trusty, utopic or vivid. But I have no experience if mixing ubuntu and debian packages works. Maybe you better compile from source to get a clean SAGA. – AndreJ Mar 2 '15 at 16:06
  • Can you explain to me how I compile from source? I am new with linux. Thank you. – Bárbara Duarte Mar 2 '15 at 16:11
  • Ok, that's no good way to start. Do you have no chance to switch to ubuntu, which is more new-user-friendly? – AndreJ Mar 2 '15 at 16:12
  • Never mind. I try like you said, with trusty and it works. Now, QGIS processing toolbox have SAGA version 2.1.4. Thanks so much. – Bárbara Duarte Mar 2 '15 at 16:15
