I was able to build gdal 3.9.0 with much difficulty. I learned
something about docker files and cmake. I was able to use checkinstall
some but not with the final install. There was something about the
installation that checkinstall did not pick up on. I found the gdal
installation tree in /tmp. I made a tar file of that to use with
alien. However someone decided that you cannot have an absolute path in
a tar file. I got one in there using the "--transform=EXPRESSION,"
parameter of the tar command. However when I ran alien it complained
about the beginning "/" of the file name. Anyways once I installed it;
it was incompatible with qgis, and did not have the correct version of
libgdal.
So then I gave up on that and downloaded the same version of gdal
as the packages that were available from the repositories.(3.3.4) I
used git to get the source code. I later found a web page that had it
in a tar file. The installation is different for this lower version of
gdal; it uses autotools. The documention for the installation did not
match up with the files. I was supposed to run ./configure but there was
not a configure file. So then I ran autogen.sh to generate configure.
I then ran configure and "configure --help to make sure that I had mrsid
built in the new gdal. I had to try until I got it pointed to its
location. Then I ran make. Finally I ran "sudo checkinstall
--install=no --pkgname=gdal --pkgversion=3.4.3
--provides=gdal-bin,libgdal30,libgdal-dev make install" I had a .deb
package now and used sudo dpkg -i to install it. But when I started
qgis it said that a plugin was missing. Searching the net I found out
that python3-gdal package was not installed. I tried to install it, but
it would not install because of the conflicts and required versions. I
thought that I had fixed that when I specified some of that with the
checkinstall command. Info on the gdal package though shows such a
dependency. You can't force the install with apt, but with dpkg you can
--force-all. the satisfy clause did not seem to work. But dpkg only
uses .deb files on installation. So I went to the ubuntu repository and
downloaded the appropriate .deb file. I then force installed it. qgis
appears to be running again with no missing layers, and mr sid works
also. It makes me mad that I had to spend all that time, because of
some government agency using proprietary algorithms and with a probable
conflict of interest.
