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 crosstool-ng@1.26.0 from 
embedded-dev/embedded-dev/packages/crosstool-ng.scm:26:2
/gnu/store/5adzqwspya97z59pgxfvchrlyddl7v6a-crosstool-ng-1.26.0

However, 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.
