Hello,I have a channel where I am trying to develop a few packages that need a new build system. I want to try and use guix to build toolchains from crosstool-ng[1] for embedded development. In an effort to guix-fiy some of my development environments I'd like to be able to use the same toolchains that I do normally but specified in a manifest for embedded projects. I have attached my channel here.
It seems to be able to build the crosstool-ng package fine with guix build -v3 -L embedded-dev crosstool-ng guix build: warning: invalid argument list guix build: warning: source expression failed to match any pattern guix build: warning: ambiguous package specification `crosstool-ng'guix build: warning: choosing [email protected] from embedded-dev/embedded-dev/packages/crosstool-ng.scm:26:2
/gnu/store/5adzqwspya97z59pgxfvchrlyddl7v6a-crosstool-ng-1.26.0However, when I try to build one of my packages that depend on crosstool-ng I get this:
guix build -v3 -L embedded-dev ct-ng-riscv64-unknown-elf
guix build: warning: invalid argument list
guix build: warning: source expression failed to match any pattern

I'm a little lost on how to proceed debugging this. It seems like it is saying it can't find the crosstool-ng package. It seemed to build fine and the package definition is in the same file.
For some background, when building a toolchain from crosstool-ng you provide it with a defconfig and it has a number of steps it goes through to bootstrap it and pull the versioned dependencies down and everything. So my plan was to have some of these packages that use crosstool-ng and just provide the defconfig as a plain file:
(define-public ct-ng-riscv64-unknown-elf
(package
(name "ct-ng-riscv64-unknown-elf")
(source (plain-file "defconfig"
'("CT_CONFIG_VERSION=\"4\"\n"
"CT_EXPERIMENTAL=y\n"
"CT_ARCH_RISCV=y\n"
"# CT_DEMULTILIB is not set\n"
"CT_ARCH_USE_MMU=y\n"
"CT_ARCH_64=y\n"
"CT_DEBUG_GDB=y\n"
"# CT_GDB_CROSS_PYTHON is not set\n")))
(version "1.26.0")
(build-system crosstool-ng)
(arguments `(#:sample "riscv64-unknown-elf"))
(synopsis "A crosstool-ng based riscv64 unknown elf toolchain")
(description "A crosstool-ng based riscv64 unknown elf toolchain")
(home-page "https://crosstool-ng.github.io/docs/";)
(license (list gpl2 gpl2+ gpl3+ lgpl2.1 lgpl3+))
))
The actual guix build system that I put together mainly follows others
that I saw in the guix source. It really just deletes a bunch of phases
from the gnu standard phases and then just runs the crosstool-ng
commands, one per phase.
There are some tweaks that I want to make here and there to clean things up before I see if this is upstreamable but I'd like to get this build debugged first.
Thanks for any tips. 1: https://crosstool-ng.github.io/
