Add Guix manifest

[ekaitz-zarraga]

Add guix manifest to make guix environments like guix environment --manifest=guix-manifest.scm

• It's not configurable at the moment.
• AVR-Toolchain is 4.9 version because 5.5 package is broken, see help-guix mailing list

Doesn't have the 5.4 or 6.3 package available?

Edit: I checked. it doesn't. That may be problematic, due to its age.

[ekaitz-zarraga]

A search returns only those (see below)
We can fix the package description of the 5.5 and make it available but it's not ready yet.

My concern here is that the 4.9 version is very old, and may be too old. And I'm not even sure about the 5.4 version.

[ekaitz-zarraga]

We are currently working on a fix for 5.5 and working on an update of the avr-toolchain. You can see the discussion here:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=39794

I hope we'll have a patch in the next weeks at least for 5.5. There's already a patch that fixes the issue, so we'll push it as soon as we can.

@ekaitz-zarraga I'm not familiar with Guix, is there any reason the latest 8.x version cannot be built/packaged for it?

Just bad packaging on Guix's side. This patch is supposed to solve it, but it's not merged yet.

On master docs/getting_started_build_tools.md has been deleted in #8252. The documentation should probably go elsewhere or d1c1808 should be partially reverted before merging this pull request.

[bricewge]

@ekaitz-zarraga Could you remove arm-none-eabi-toolchain since it conflict with avr-toolchain? You can also drop the version specification for avr-toolchain, 5.5 is working correctly now and adding python silence the warning “Python 3 is not installed. [...]”.

With these modifications I was able to successfully build helix/rev2 as well as 40percentclub/luddite.

[ekaitz-zarraga]

@bricewge Did what you proposed but arm toolchain is supposed to be used by other parts of the project so the manifest proposed here is only going to be unusable for some keyboards (I think).

[bricewge]

Thanks @ekaitz-zarraga that was quick! BTW it's python instead of python3.

Do you have any example of such a keyboard?

[ekaitz-zarraga]

@bricewge done.

I don't have any in mind but if that's part of the projects requirements it should be for a reason. :)

We use the ARM toolchain to build firmware for STM32 microcontrollers (and some NXP chips used by the ARM Teensys, and the ATSAMD51J18A that the Massdrop boards have) using ChibiOS' HAL. If there is a conflict between it and the AVR toolchain that will need to be fixed upstream.

@ekaitz-zarraga, did you manage to ever flash a deyboard on guix? I'm afraid I'm a bit stuck with udev and was wondering if you had any success. Thank you.
