Re: [Tinycc-devel] Building sudo?

[Sudipto Mallick]

Interesting project.
Because you're building the smallest possible usable system, I'd
suggest using a port of OpenBSD doas(1) e.g.
https://github.com/slicer69/doas .
doas is smaller, simpler alternative of sudo. I think it suits your
project well.
Also, a salute to you for building an OS using tinycc.

Re: [Tinycc-devel] Building sudo?

Don't be surprised :D

Im built this system from scratch (https://github.com/prologic/ulinux)

Basically the build system consists of just tcc and make. I was able to get
musl libc in the mix too, but quite a few things I had to build on a
separate host system to bootstrap the system.

Anything in the ./pkgs/ directory has to be bootstrapped on a host system.

Everything in ./ports/ is able to be built on a running uLInux system
itself.

My original goal was to build the smallest possible useable Linux, it
actually started out as a fork of Minimal LInux Live (you may have heard of
it?) then quickly turned into Minimal Container Linux (
https://github.com/prologic/minimcal-container-linux) and now uLinux (
https://github.com/prologic/ulinux).

The idea  is still to have the smallest possible useable system, so this
means shoving in binutils and all manner of GNU software is out-of-scope as
it tends to be rather fat and bloated :)

Are you starting to see the picture? Fortunately uLInux is capable of
running containers though including Docker and a custom container system
called box so I can actually build things in a container then copy the
artifacts to the host.

cheers
