Use a Containerfile with multi-stage builds to sort out all the missing dependencies and build the RPMs.
Install RHEL 9.4 minimal. Clone this repository to your physical
or virtual guest instance of RHEL 9.4. Edit demo.conf to set SCA
credentials. Next, register with SCA and pull updates
cd ~/build-flightgear-rpms
sudo ./register-and-update.sh
sudo reboot
Install podman
cd ~/build-flightgear-rpms
sudo dnf -y install podman
Prepare to build the RPMs. Login to the registry using your Red Hat customer portal credentials.
mkdir -p flightgear-rpms
podman login registry.redhat.io
Build the FlightGear RPMs
podman build -f Containerfile -t built-fg-rpms -v $(pwd)/flightgear-rpms:/rpms:Z
The RPMs will be in the flightgear-rpms directory when the container
build finishes. You can discard the -devel RPMs as you will no longer
need those.
rm -f flightgear-rpms/*-devel*
Not all of the RPMs are necessary to install FlightGear. You only need
the ones for missing runtime dependencies. With a little trial and error,
I narrowed the list to everything in runtime-dependencies.txt.
