Build in test environment in progress at time of writing. After yum install wxGTK3-devel unixODBC-devel, the following seems to be working to make it pick up the correct version of wxGTK3:

Obtain source:

$ wget https://downloads.sourceforge.net/project/saga-gis/SAGA%20-%207/SAGA%20-%207.0.0/saga-7.0.0.tar.gz
$ tar xvfz saga-7.0.0.tar.gz
$ cd saga-7.0.0/

put a wx-config symbolic link early in the PATH pointing to the wx-config-3.0

$ mkdir wx-tmp
$ ln -s /usr/bin/wx-config-3.0 wx-tmp/wx-config
$ PATH=`pwd`/wx-tmp:$PATH
$ wx-config --list  # make sure that it says that 3.0 is being used by default

then do the build

$ autoreconf -fi
$ ./configure --prefix=$HOME/saga
$ make
$ make install

Requires #187

Build successful. Tested the gui as compiled above, on a machine without the above devel libs, and it seems okay (tested with some shapefile from under ESMValTool). This is a manual build and still need to build an RPM.

This is a complex GUI. Not available on conda-forge/anaconda-default.

Will move ticket to extra-sci-packages repo. I looked to see whether it could be installed under /apps/jasmin/supported, but it seems likely that the above mentioned extra RPMs that need to be installed are required at run-time, not just compile time, so these would need to be added as RPM dependencies.

I'm tempted to close as WONTFIX given the age. Low priority.

[alaniwi]

On sci2-test, installing the RPM dependencies adds total ~50MB.

Build has changed. No sign of a configure or configure.in file. New instructions at https://sourceforge.net/p/saga-gis/wiki/Compiling%20SAGA%20on%20Linux/ These fail because the cmake version is too old.

This is getting too complicated, and given that I have not seen further requests for this software, now going to close as WONTFIX.

[alaniwi]

Reopening, as we have had another request. Helpscout 68144. Will try on Rocky 9.

No longer complaining about cmake version, but compilation fails at 11% with:

According to https://sourceforge.net/p/saga-gis/discussion/790705/thread/8da5c505ac/, "For newer SAGA versions you require at least wxGTK 3.1". The yum install wxGTK3-devel unixODBC-devel prior to the build gave wxGTK3 3.0.5.

[alaniwi]

RPM wxGTK was already installed - which is 3.2.2. Undoing the previous yum install and retrying the build, it gets past where it hit the error before, which is good to know, but the undo will also have removed unixODBC-devel, and in fact gdal-devel is also a documented dependency which is missing (according to instructions) -- so although the build is on 40% and still going, I will stop it and try again with these dependencies installed.

[alaniwi]

Made an RPM. Note that build time is about 20 minutes.
