To build a Glibc toolchain I use the CLFS-embedded instructions mixed 
with LFS instructions and I use the packages of the latest stable 
release. Same discourse goes for a musl toolchain: clfs-embedded 
instructions and LFS packages

https://github.com/landley/mkroot
 has a toolchain build script
that configures
Rich Felker's musl-cross-make for several architecture targets.
There are
binaries of the output at
http://mkroot.musl.cc/mcm-i686-gcc-7.3.0/
 if you want
to skip the source build. (What mkroot itself does is build minimal
boot-to-a-shell-prompt systems for each of those architectures.)

I'm also engaging with the Android NDK guys to try to get that
fleshed out a bit
more as a bionic build toolchain.

I don't have any glibc variants, but in theory there are debian
toolchains for
that? (Sorry, gnu/libc isn't very interesting anymore...)

I'm vaguely trying to do something like LFS for Android:

https://landley.net/toybox/about.html


But that's a longish-term project aimed at a moving target...

My previous project along these lines was a lot closer to LFS:

Thanks all for your replies.
It does, however, not answer the first question, whether or not CLFS is 
still alive or is planning to come alive again.
Due to lack of answers I - for now - assume that neither is the case. 
Still, the documents as well as your answers  provide some pointers 
which I shall incorporate in my current project.


Thanks again and a happy new year!

-- Frans.

Re: [Clfs-dev] Is CLFS still alive?

2018-12-28 Thread Tom Armistead 
 
I only speak for myself.  I've used CLFS in the past but am not in any 
authority regarding it.

If you need a cross-compiler, I have found that the crosstool-ng project is a 
good source to help you do that.  

LFS can be (with mods) built on other architectures besides the x86/64 
machines.   You have to make some changes to the instructions (particularly in 
the tool chain building) but it can be done.

If you need to cross build a Linux system, there are number of projects that do 
that.  I'm not very familiar with them but buildroot is one that I am aware of.

Tom
