Yet I get the following errors, which seem to be some dependency issue - but I am not able to resolve it. Below is the full output of my installation attempt:

(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

not dependent on input files

Any help on this would be greatly appreciated.

Dear Lars,

please try to install flair (and flair-geoviewer) from the .tgz packages manually.

You may need to install these additional packages: ed libX11-devel tk-devel python3-devel (The package name may be different on AlmaLinux tough)

Cheers,
David

Dear David

Using the .tgz archives I was able to install flair and flair-geoviewer. Thank you very much.

For future reference, I used the following commands:

Additional dependencies:

sudo dnf install ed libX11-devel tk-devel python3-devel python3-tkinter g++

Installing flair:

tar xzvf flair-3.4-5.2.tgz
cd flair-3.4/
make -j 8
sudo make install

Installing flair geoviewer:

tar xzvf flair-geoviewer-3.4-5.2.tgz 
cd flair-geoviewer-3.4/
make -j 8
sudo make install DESTDIR=/usr/local/flair

To get pillow systemwide I used:

python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow

What I also noticed is that you have to have a physical display connected to the PC during the compilation … else the flair-geoviewer compilation fails because it cannot detect the display …

Out of curiosity: why is it not working with the flair.repo, do you know?

Thanks again for all the help.

Cheers,
Lars

Dear Lars,

the repository is a general one for rpm based systems, and the package is compiled with a recent Fedora distribution (I belive).

Since AlmaLinux (and Centos, RedHat, Rocky, etc.) are server distributions, they have older system packages (like glibc). These older versions are missing features which are present on the current desktop Linux distributions and needed by the precompiled flair-geoviewer package.

Compiling from source will only use the available features on the actual system.

Cheers,
David
