[PATCH 00/23] guix: Add avr as a platform. |
|
Date: |
Fri, 29 Sep 2023 11:13:33 +0200 |
Hello Guixers,
This adds avr as a platform to GNU Guix allowing to cross-compile
packages to it.
For the impatient, with this patch series one can build the provided
unity package with this invocation:
./pre-inst-env guix build unity --target=avr
It uses the AVR Libc as the default libc and fully builds a
cross-compiler using the AVR Libc instead of building them separately
like it's done currently. This could allow to use other of front-ends of
GCC in the future if possible, however, Fortran and Objective-C
front-ends don't build right now for AVR, haven't tested any other
front-ends.
This also adds the cross-toolchain module for instantiating
cross-toolchain packages, this is to avoid each platform defining a
module like avr to instantiate a toolchain, this helps in avoiding
circular dependencies as cross-toolchain should depend only on
cross-base and that'd be it.
I think could've added cross-toolchains there for MinGW though, but I
don't have a need for it but allows others to do so. Perhaps it could
be a requirement that to add a platform one needs to add a
cross-toolchain package.
I enabled multilib support for AVR as most embedded platforms will need
it, which makes me think, perhaps should the platform record contain a
`mutlilib?' field?
Information about individual patches:
On [PATCH 05/23] I didn't find a better way of deleting the
--disable-multilib flag from GCC configure flags, if anyone has a better
idea let me know.
The [PATCH 01/23] and [PATCH 02/23] are optional but there
might be some platforms defined in the future that don't have
a proper libc and it still should be fine to use these I think.
The [PATCH 21/23] fixes a bug in the meson-configuration module
and can be applied independently.
Feel free to cherry pick the interesting/trivial patches.
PS:
I CC'ed the embedded team and Maxim Cournoyer as I saw his current work
on QMK firmwares and could be of interest to him.

Wow! Thank you for all the work on this.
Patches slightly modified (indentation, wording on commit messages) and
pushed!
