I posted on answers.ros.org but these latest errors seem Fedora-specific. I'm getting all of these undefined reference errors

I did find a bug report mentioning Matlab/Scilab having conflicting or out of date libraries, https://bugzilla.redhat.com/show_bug.cgi?id=1829790 but we don't have Matlab installed on this server.
Is this worth reporting as a bug?

First we should clarify that you're now switching to ROS 1 stuff. Catkin is the buildsystem and build tool for ROS 1, you'd use ament and colcon in ROS 2.
ROS 1 and ROS 2 packages are generally not interchangeable. Many packages have branches for supporting both ROS 1 and ROS 2, but you can't generally drop a ROS 1 package into a ROS 2 build environment and expect it to work.
Assuming you're now building a separate ROS 1 distribution from the ROS 2 build you were discussing earlier:
The gl_dependency package only appears to be used in ROS 1, and it's really only a dummy CMake package to make sure some depenencies are installed. You're probably seeing a generic compiler verification check fail in CMake.
We could try skipping the compiler check since the gl_dependency package doesn't really need it, but this really indicates that theres something wrong with your build environment. I'm skeptical that you'll get any of the C/C++ packages to compile correctly, not just gl_dependency.
To be honest, the error doesn't even really seem related to ROS at all.
Just a hunch, but you might try ensuring that glibc-devel and boost-devel are installed, and CMake is up-to-date. Then remove your build and install directories and start again.
Oh my bad I was testing ROS 1 from this older tutorial:

The ROS 2 error is from running colcon build --symlink-install

Again, this is the type of thing that is typcally handled on answers.ros.org...
Noted; I'll head there after this.
