Windows or Linux

[Kernelpanic]

ah yes compiling from source
that is a nightmare for me

Tell me about it... I tried setting up gcc under Puppy Linux, and ran into all sorts of issues with missing header files and the like. 

I'm hearing about this for the first time. The GCC is standard in every Linux distro, if it's not part of the Puppy distro then forget Puppy. 
In earnest, is there no guide on how one to correctly install the latest stable GCC 11.3; I think?

I have install WSL 2 with SuSE 15.3 under Win 10 Prof. In SuSE one install either via Yast2 or with "zypper". I have GCC 11.3 installed.

It is under /usr/bin and reads: gcc-11. This is of course much too cumbersome, so one change it with (as root): ln gcc-11 cc.
Now you can call the GCC with cc.
