Re: How do I reference the src checkout in a package?

[Zhu Zihao]

Try `#$(package-source this-package)` in the builder gexp.

Or you can try `(assoc-ref inputs "source")`, but be careful, this is
undocumented behaviour and it may change without notice and break your
recipes.

OT: it's better to ask for help in help-g...@gnu.org :)

How do I reference the src checkout in a package?

[jgart]

Hi,

I need to reference the carp checkout in an environment variable so that
carp can find the libs it needs:

/gnu/store/0xhn0vyjlcb2dv1h2333vhbj7j1vvrr6-carp-0.5.5-checkout

How can I do that?

* carp package definition

```
(define-public carp

I tried doing a "guix pull" for armhf-linux on a Raspberry Pi 2 B
(Raspberry Pi OS with Guix as package manager), and also on a more
powerful x86_64 machine with "guix pull -s armhf-linux -p /tmp/arm-guix",
but it fails in both cases when building "guix-packages-base.drv" (more
precisely the process hangs, CPU usage at 0 and memory around 2 or
3 GB).

The build log ends with:
--8<---cut here---start->8---
compiling...  95.6% of 344 files
GC Warning: Failed to expand heap by 8388608 bytes

Too many heap sections: Increase MAXHINCR or MAX_HEAP_SECTS

Does someone have an idea how to fix this?

Git 2.38.0 gained support for this via a --force-in-body-from option and
the associated format.forceInBodyFrom config variable.

Ya, I don't think that will be too hard. There's a nixpkgs definition
here that shows what will be required:

https://github.com/NixOS/nixpkgs/blob/nixos-22.05/pkgs/development/compilers/carp/default.nix#L4

Yup!

Carp is a lisp that handles memory management in a similar way to
Rust. Not many other langs like that.

all best,

Re: Antioxidant (new rust build system) update - 100% builds

Hi Maxime,

This is so great.

It's been downright fun watching antioxidant steadily grow in 
power.  Thank you so much for working on it!


Kind regards,

Antioxidant (new rust build system) update - 100% builds

[Maxime Devos]

Hi,

100% (rounded up) of the packages build with antioxidant, though a very 
few still fail to build: .


So far, work on antioxidant has been done in a separate channel for 
convenience, but given that almost everything builds now, I think it's a 
good time to start looking into moving it into Guix proper (initially as 
a branch, as there are some remaining TODOs like e.g. 'why are some of 
the binaries made with antioxidant larger than with cargo-build-system + 
fix that').


More concretely, this would mean changing the 'runtime' transformations 
done by 'antioxidant-packages.scm' (in the style of '(guix)Defining 
Package Variants') to source code transformations ("guix style").


IIRC, Ludo' has some "guix style" patches for moving #:cargo-inputs to 
'inputs' and such; those could perhaps be used as a basis.


Greetings,
Maxime.

Looks sort-of but not quite a duplicate of 
 (‘guix shell’ skips profile 
collisions checks) to me.
