How to compile SAGA GIS from source on Ubuntu 24.04.3 LTS

-

With reference to the source 'Compiling SAGA on Linux'.

https://sourceforge.net/p/saga-gis/wiki/Compiling%20SAGA%20on%20Linux/

You can also simply run these modules in QGIS but you would miss out on some excellent advantages such as having multiple map windows synchronized and a simple interface.

Current 'Debian/Ubuntu' libraries only go up to version 9.2.0. 

This will install the latest version (currently 9.10.0).

1. ~$ sudo apt install libwxgtk3.2-dev libgdal-dev libproj-dev libpq-dev libpdal-dev libopencv-dev libhpdf-dev unixodbc-dev

(You may see this error:) 'E: Unable to locate package libpdal-dev'  this does not prevent continuation of compilation process.

2. ~$ sudo apt-get install g++ cmake cmake-qt-gui make libtool git


3. ~$ sudo apt install libwxgtk3.2-dev


4. ~$ sudo apt install libcurl4-openssl-dev


5. ~$ sudo apt install g++ make cmake git swig python3 python3-dev python-dev-is-python3


6. ~$ sudo mkdir /home/devel


7. ~$ cd /home/devel


8. ~$ sudo git clone git://git.code.sf.net/p/saga-gis/code saga-gis-code


9. ~$ cd saga-gis-code


10. ~$ sudo mkdir build


11. ~$ cd build


12. ~$ sudo cmake ../saga-gis -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_INSTALL_RPATH=/usr/local/lib -DPYTHON_INCLUDE_DIR=/usr/include/python3.6m -DPYTHON_LIBRARY=/usr/lib64/libpython3.6m.so -DPYTHON_EXECUTABLE=/usr/bin/python3.6 -DWITH_TRIANGLE=OFF -DWITH_SYSTEM_SVM=ON -DWITH_TOOLS_VIGRA=OFF -DWITH_DEV_TOOLS=ON -DSVM_INCLUDE=/usr/include/libsvm/svm.h


13. ~$ sudo cmake -LA


14. ~$ sudo cmake -LAH


15. ~$ sudo cmake-gui

Then...(in the pop-up box that appears enter the two paths as shown below the images)

Click on the 'Configure' button first.

 
  
Then click on the 'Generate' button
 
 
You should see 'Generating done (0.7s)'
  
 
"Browse Source", e.g. /home/devel/saga-gis-code/saga-gis
"Browse Build", e.g. /home/devel/saga-gis-code/build

"Configure"   then...

 If all went well, press the "Generate" button otherwise resolve/edit the values marked in red, configure again, and finally generate the makefiles

    
16. ~$ sudo cmake --build . --config Release
17. ~$ sudo cmake --install .
18. ~$ sudo ldconfig
19. ~$ saga_gui &

This post follows on from my previous three (most recent first in list) linked below. There is no doubt that in just a short time from now we will probably see a 'one-click' installer to by-pass the next steps but a least this method allows you to change 'in/out' the individual libraries if there is are updates using the usual ' sudo apt update && sudo apt upgrade '. http://www.paulshapley.com/2016/08/qgis-server-bringing-map-into-browser.html http://www.paulshapley.com/2016/07/how-to-install-qgis-server-on-ubuntu.html http://www.paulshapley.com/2016/04/how-to-install-postgresql-95-and.html 1.  Firstly...Create a new QGIS project, add your layers from PostGIS, Shapefiles or raster (geotiff), style and symbolise those layers, set the projection and ensure you've set up your 'OWS Server' in 'Project Properties'. 2.  Let's install the 'Lizmap' Plugin first by going into the 'Plugins' menu then 'Manage...

Install PostreSQL 14 and PostGIS 3 on Ubuntu 22.04 LTS

I always get frustrated when I update my version of Ubuntu to the next LTS and want to do some development work with the latest stable releases of PostgreSQL and PostGIS.  I usually trawl a few web sites to find out what has changed but each time there are slightly different ways of doing the upgrade depending on where you land and who it is doing it. So...to (hopefully) help other people out wasting half a day or so here is my solution.  Hope this works for you too... To completely remove all previous installed versions of Postgresql/PostGIS libraries and docs if there is a previous version:-  :$ sudo apt --purge remove postgresql postgresql-*  :$ sudo apt autoremove  Remove old folders:-  :$ sudo rm -rf /var/lib/postgresql/  :$ sudo rm -rf /var/log/postgresql/  :$ sudo rm -rf /etc/postgresql/   Remove the old 'postgres' user:- :$ sudo deluser postgres    Restart System:-  :$ sudo shutdown -r now then:-  Update Syste...
