It is just a hobiit, I have been compiling and maintain my own linux stuff = for as long as the site LFS started (about 22 years). With gcc-2.7.x and libc5, you can compile the whole distro in an hour, Nowadays, it take me 24 hours on a 4 cores machine. I can't remember exactly which version of glibc or linux started requiring = -O2 So I ended compiling the whole thing in -O2, otherwise they would simply refuse to compile. It is still the same with the linux kernel. (I've just tried it) Just to be rebelious and fun, I manage to compile the whole thing except the kernel and bootloader (syslinux still requires at least -O1). Anyway, Thanks for listening to a old man's ramblings. > > Thanks > > On Tue, Mar 1, 2022, 04:29 naruto canada wrote: > >> hi >> >> Big thanks to musl developers.
