Hi. What do you mean by "I cannot follow the rest of the thread"? Too technical?
I listed just above the basic libraries that are needed:
- libSDL2-2.0.so.0
- libdl.so.2
- libX11.so.6
- libc.so.6
In the terminal, try:
ldconfig -p | grep libdl
If libdl is not installed, there will be no output. If it is installed, you will get a line for each version available. Please do that for all of these.
You can also find your sdl version (if it is there) with:
sdl2-config --version
Did you try running the simple cube that works without any external libraries?
