Question: How do I compile the Linux kernel?

By which I mean, what compiler flags, options and configs should I look out for, such that my kernel will actually succesfully run? I am talking about QEMU without KVM as the platform.

Hi! If you're thinking about compiling a custom Linux kernel, the two most popular options are Gentoo and LFS (Linux From Scratch). There are walkthroughs available on https for both of these options.

However, if you just want to play around with Linux I would recommend choosing a distro flavor that you like and not worrying about compiling a custom kernel, which is a very complex process! Your choice though.

back when I used to do it, there was a TUI (actually even a GUI in GTK) which would configure everything including flags and so on.

gentoo is the popular distro for that. Have fun im sure it will be a blast ๐Ÿ’€

I'd recommend getting to know your hardware before doing this. Otherwise you simply wouldn't understand the options....i but feel free to experiment....i remember creating quite a few broken kernels before i managed to make one that worked. Also as @gyaradong mentions there used to be a nice curses TUI to set the options, look for it
