Thanks for letting me know some usual places for apps, installs and such in a linux system. I'll be able to look better for some stuff I was looking before and a few more needed commands to learn.
Unfortunately, 7kaa executable, nor its binary file, is in neither of those locations.
/usr/share/applications/, I have a great number of .desktop files of installed apps., which I'll look into and try to mimick for creating a shortcut, but there's nothing more than .desktop files.
/opt, I have just 2 .zip files and their respective extracted contents, from when I was trying to install some missing libraries.
/bin, there is no 7kaa stuff at all, no folders, no files. In
/usr/share, also no 7kaa stuff.
/home/$USER/.local/share/7kfans.com/, I have a few save files from my test play and 2 DAT files for settings stuff. Then, there's the folder I created, where I placed and then extracted the source tar file, in
/home/$USER/AXIA/. In there is the 7kaa build folder and files.
/usr/local/bin/7kaa, there's a 7kaa file, no extension, almost 27Mb size. When I click in properties in it, it says "shared library (application/x-sharedlib)".
/usr/local/share/7kaa, there are a lot of files from 7kaa installation. I'd say almost all there are in build folder, but no 7kaa file.
/usr/local/share/doc/7kaa, there are some text files, readme and such.
/var/lib/app-info/icons/ubuntu-focal-universe/64x64/7kaa_7kaa.png, I believe there's a possible icon I could use for the shortcut, when I create it.
Side question 1: Can the build files and folders be safely deleted after a successful install from source code? Or are they still needed?
Side question 2: I just remembered I should have said before that I had previously installed this 7kaa game from Software app (Software/Games/Seven_Kingdoms), with its source being "ubuntu-focal-universe".
I removed it because it wasn't updated, nor it seemed it was ever going to be. In it's page in Software app, it says "Updated --> Never". It's a rather old version. That's why I decided to build it from the fan site and learn some linux stuff in that process.
When we click to remove an app from Software, repository or whatever it's called, are all those files really removed or do some (a lot?) of them still linger in the system?
