Hi,
I am an amateur radio operator who was going to try using a logging program called CQRlog to log my radio contacts, but I have changed my mind because it seems there are too many other packages needing installed that go beyond my abilities.
For installation in 22.04, I used the instructions to install "lazarus" and "git" and then attempted to compile using make. See here:
https://www.cqrlog.com/comment/10511#comment-10511
However, I have changed my mind and want to uninstall lazarus and git as well as the compiled CQRlog. I would appreciate the proper commands for the uninstallation and thank you in advance.

Rule of thumb:
Any time you're off-roading on a computer,
doing something you have no experience with,
make a backup first. That's what I do.
In fact, if you change platforms, that's one of
the first tools you want to locate. "How do you
do backups on this platform?". Because, you'll be
needing it. There will always be pooh to step in,
and backups are for cleaning off your shoes.
Most platforms have "dd" or "disk dump". It can be
used for "safety backups", until you test a more
intelligent backup tool and prove to your own satisfaction
that the method really works. The box I'm on now,
that's what I did. I did a few "dd" of the whole
disk drive (takes hours), just so I could be
sure I had a "restore image I could trust".
Real backup tools take a lot less time (10 minutes).
*******
sudo synaptic # Or start it from your menu.
Find "lazarus" metapackage and select either "remove"
or select "complete removal". Either of them will neuter
the execution of the program. Their /usr/bin or similar
stuff, should be missing then. Click the "Apply" button
and verify that the expected dependency list is also
marked for Removal. If it threatens to remove your entire
Desktop Environment (DE), stop, close Synaptic program,
and ask for help. You always check what a command
"proposes to do", in case it's nuclear. Booby trapping
the tree, is a relatively new phenomenon, and years ago,
nobody did stuff like that. It never hurts to read what
is in that window, scroll down and verify.
Now "git", I assume that wasn't installed with the original
OS installation, so you can use Synaptic again, select "git"
and just that package should disappear. The git portion
of the repo has a ton of helpers, but on mine at least,
it doesn't look like all the helpers got loaded on mine.
So when I select "git" for "removal" in Synaptic, the
number of packages to be removed should be minimal.
*******
The next question would be, what build commands did you issue ?
This one, is harmless.
cd CQRlog_directory_name
make # Added some files to CQRlog_directory_name, nobody cares.
Whereas this one, is not.
sudo make install # Put stuff in /usr/bin, in some library area, some config area...
I normally do one of these first, before the previous command, to see
the steps it would have executed.
sudo make -n install # Don't allow the changes to go to the tree.
If you did actually "make install" then
now you have to check the Makefile with a text editor and
see if there is a remove: target. If there actually was
a remove target, then to counteract the previous command,
I could try this, but if there is no remove: target, then
this command cannot resolve your request.
sudo make remove
That's to remove the executable (if you got that far), from the slash tree.
And you MUST complete your tree-cleaning, before doing the next step.
If you did the next step first, then it would no longer be
possible to do "sudo make remove" or similar. You remove the
side-effects of your work, before cleaning up the scene of
the crime.
*******
When you ran git, to pull in source, you were cd'ed to
a certain directory. Go back and cd to that directory.
cd ~
cd Downloads
cd workdir
ls # Verify a CQRlog directory is there
rm -Rf CQRlog_directory_name # Could be some release numbers on the name
Alternately, the safer option, is use the Nautilus File Manager,
select the "CQRlog_directory_name" when you see it in the window
of that program, and toss it in the Trash. After that, check the
Trash, verify what's in the Trash, then select "Empty Trash"
to clean out the trash bucket.

Thanks for the help, but I have some questions:
Synaptic reveals several versions of Lazarus as shown in this screenshot:
https://i.imgur.com/VJdZyV9.png
If I just mark "lazarus" for complete removal, the others are NOT highlighted to be removed as well. Therefore, should I also be marking "lazarus-2.2", "lazarus-ide-gtk2", etc... basically everything with "lazarus" in the name here, or ? Also, I understand "fpc" was also installed at the same time (according to https://ubuntuhandbook.org/index.php/2021/11/install-lazarus-ide-ubuntu/). Should I do a complete removal by marking "fpc-source-3.2.2"? What about the "lcl-2.2" and others?
Interestingly, Lazarus 2.2.0 also appears in the Software center as installed (with removal option):
https://i.imgur.com/QdXNgH9.png
At least "git" is much simpler with only a single entry to remove. It also does NOT appear as Lazarus does in the Software center.
As for the next commands, the order is shown as indicated in the cqrlog post that I linked to, but will repeat here:
git clone https://github.com/ok2cqr/cqrlog.git
cd cqrlog
make
sudo make install
After the steps from git clone to sudo make install were done, CQRlog then appeared in my programs. Of course, when I tried to open, I get the messages about more files needed and that's when I decided to not use it. It appears in my programs list as well as the Software Center with the uninstall option.
I'm a bit lost when you begin discussing the build commands, which is why I repeated them here. Where is the Makefile located? In the CQRlog directory?
"And you MUST complete your tree-cleaning, before doing the next step.
If you did the next step first, then it would no longer be
possible to do "sudo make remove" or similar. You remove the
side-effects of your work, before cleaning up the scene of

Sorry, I don't follow. How do I complete the "tree-cleaning" and such?
Since CQRlog is showing in the Software Center with uninstall option, might it be simpler to just uninstall it from there? As a side note, interestingly, although CQRlog shows up in Synaptic, it does not show as installed even though it does in the Software Center.

When you select "lazarus" as a metapackage, it seems to have selected elements
of the latest version for inclusion in the install.
By selecting lazarus for removal, in principle at least, it should be removing the 2.2 version items install. If it did not, you could use the search to list all lazarus instances, and manually remove the subpackages
if any remained installed.
When the boxes are empty, the files are not on the machine (fresh install). The listing is a list of things the Repository has. When the boxes are
filled ("ticked"), like in the 2.2 version items, then at some point the files were downloaded and installed. When you do the remove, the files
should be removed from active participation in your tree. OSes always have caching mechanisms, and if you were tight for space, it might be a significant effort to remove them all. Perhaps "complete removal"
ensures that any .deb files still on the machine and related to that,
are removed.
There are also commands for the package manager, that notice dependencies that don't have a master program, and those can be removed automatically. Sometimes on a Software Update, you will notice an effort is being
made to consolidate the contents of the tree, so only "wired together stuff" is kept.
But for the time being, I interpret your request as "how do I prevent what I've done from interfering with normal day to day operation". I have
not gone the extra mile to "make my slash as small as possible". That's
out of my pay scale. Don't know how to do it. Would take hours and
hours of research. I've used several OSes where I don't know how to
do that, comprehensively and with confidence. That's "work" as it were.
I do clean out browser caches, because at least I could find those.
*******
During your build, if you do
sudo make install
then that puts items in /usr/bin or /usr/lib or the like. To prevent interference with day to day operation, maybe you would want to remove /usr/bin/CQRlog executable.
If you go back to the build directory and run
sudo make -n install
and do a dry run, the trace in the window will give you some idea
where it has stored its stuff. You could manually go into the tree
and remove the items. But I don't recommend doing that unless you're
good at that sort of forensics.
Executing sudo make -n install does not always run to completion.
The command can fail at some point, because it's not really installing
stuff, and some order-of-execution issue might affect its ability to complete. I use commands like that (without EVER installing the package),
to see what the build tools think the important items are. Like whether
it installs libraries or not.
Makefiles can be in each subfolder of the build tree. Each subfolder
needs to be told what to do when make sees "source.c" and that it
should be compiled to "source.o". The template at the top level,
such as Makefile.in , it can inform the ./configure run, how
to build a custom Makefile in each subfolder. Using ./configure,
is one way to have the build tree make custom Makefile items.
Before ./configure came along, the Makefile was static and the
build was "one flavor only". You wouldn't even need a template, if
there was only one way to use the build tree, so each subfolder
would have a pre-made Makefile.
But you would normally be CDed to the top level of the build, when
you did the build or when you did the install. By being at the
top of the build tree, all of the install materials from
all of the subfolders, are considered. And the Makefile
will have an "install: " target followed by a list of
module names, like "source.so.2" shared library.
Make is not the only build tool. There is CMAKE, Ninja, I don't
think I can do a credible job of listing all of them. I don't like
all of them equally, because some are a rat bastard to get working,
as if the developer just doesn't care.
Adobe released a CMAKE one once, where they failed to integrate the
"demo app" into the tree, and it took me *one week* of work to fix that.
Then I discover the "demo app" is utter crap. And that really
explains it all -- no end-user got as close as I did, because
the build tree was broken. I did the extra work to discover
the developer of it... was a "munchkin" :-\ But that's how it
goes when you compile from source. That's part of the terrain.
I've also acquired FOSS tarballs, where one file is missing
on purpose, because the individual "wanted free storage for
their executable", but did not want people compiling from
source. I've had a variety of experience with this stuff,
and there are more than a few scumbags out there.
*******
Leaving library items behind is only an issue if it interferes
with some other, later project. I would put in an effort to
see they are removed. Maybe they can be spotted by their
datestamp, and a simple listing in time order, will identify them.

I decided to go with my most recent back up, from late Jan, 2024. Most of what had changed were emails and browser, so just transferred over the config files and good to go. I didn't feel confident trying to uninstall the tools and the compiled program without messing something up. Needless to say, I WON'T be trying to use this program again anytime soon. I've tried installing it in the past and was never able to get it working correctly even then. It does have a lot of features if I ever did get it working, but I use a much lighter and easier to install program that is adequate. Only issue is that the one I use hadn't been updated for over 5 years, so I suppose one day that it will stop working but for now it works fine. Thanks again for trying to help
However, I have changed my mind and want to uninstall lazarus and git
as well as the compiled CQRlog. I would appreciate the proper
commands for the uninstallation and thank you in advance.

I doubt you would screw things up.
Really, the biggest liability, might be something left
in the tree after
sudo make install
But there may be ways to work on that, such as listing
all files by date. And noting the particular day
you blasted them in.
*******
These are two commands for listing files
or listing directories, into output listings.
cd ~/Downloads
df # This lists various mounted file systems, like from the automounter
# In the example, a limited portion of tree is being listed, but you can use / instead
find /media/WIN2KAS -type d -exec ls -al -1 -d --full-time {} + > directories.txt
find /media/WIN2KAS -type f -exec ls -al -1 --full-time {} + > filelist.txt
And just for you, this version of the filelist example,
will make it so that column one is a timestamp suited to
sorting in LibreOffice Calc. There are two timestamps plus the filename.
The first field has been made ten digits wide, with leading 0 added
if the field is not wide enough to make ten digits. In LibreOffice Calc
you can use Data:Sort just like excel, with a default extended selection.
sudo find /media/WIN2KAS -type f -exec stat --printf='%010Y %y %n\n' {} + > statlist.txt

I appreciate this and will try and refer to it in the future, but I'm considering installing a "system restore" feature, similar to Win, if
one is available for Ubuntu, similar to one like featured here:
https://ostechnix.com/systemback-restore-ubuntu-desktop-and-server-to-previous-state/
Not sure about the software there, but I do wonder if anyone can
recommend something similar so the next time, I simply take a snapshot before installation and, if no good, restore to original snapshot?
