Pop_OS and RCB3.19r3

Pop_OS is based on Ubuntu 22.04 LTS.

As I could not get RCB to run on Ubuntu 20.04, I attempted U22.04.1, U20.04.5 and also the Mate versions of both. All installation of the OS failed... Some problem with the ISO images...

All of the following on a fresh install. Nothing but the OS.

Pop installed without issue.

Installed Geany and executed then exited...

Downloaded and extracted RC3.19r3.

Within RC3.19r3 directory: ./install.sh (entire install completed ok)

Ran the RC geany script.

Within Geany' 'Set Build Commands':

Modified 'compile','gen key' ,'execute' and 'distribute' to the appropriate directories.

Loaded "beast Demo" to test Geany and RCB.

"Beast" compiled successfully but failed to execute.

Following message appeared:

/home/john/Programs/rcbasic/rcbasic: error while loading shared libraries:

libSDL2-2.0.so.0: cannot open shared object file: No such file or directory
------------------
(program exited with code: 127)
Press return to continue

I do not recall having to install SDL2... or did I do something wrong again?

I think I need more coffee...  Installing 5 Linux OS's is about as much as I can handle... lol

ps: Forgot to mention: Beast ran ok via Studio. But when exiting Studio 'rcbasic_studio_run' was still running. Had to terminate process via system monitor.

Also, in reference to SDL2, you mentioned... "LD_LIBRARY_PATH before launching geany.". How exactly is that done?
