Failing HEAD compiles

Jasem,
FYI, the latest KStars HEAD doesn't compile on my Ubuntu 22.04 telescope
computer.
Specifically below is part of the compilation output with the error.
Since the error was in fitsdata.cpp, I looked at the recent changes to it,
and checked out the software just before
> git checkout e3812799e54518ba7d3427cf2a68d6201a3786bd
This avoids this recent submit:
commit dc54426dee3765674f1de697c94ad5ff0d3f77d4
Author: Jasem Mutlaq <mutlaqja at ikarustech.com>
Date: Wed May 13 19:01:04 2026 +0300
Support loading .fits.gz and .xisf.gz in the viewer
kstars/ekos/align/align.cpp
kstars/fitsviewer/fitsviewer.cpp
Once I did that, it did compile.
So, Jasem, any chance you can ask your favorite AI how to fix that for
22.04?
Thanks,
Hy
