Re: Can the builder access channel code?

[Pierre Neidhardt]

My bad, I had forgotten to add my build-system to the list of build-side 
modules:

(define %foo-build-system-modules
  ;; Build-side modules imported by default.
  `((my-guix build foo-build-system)
,@%gnu-build-system-modules))

This fixes it, thanks for you help!

So your derivation tries to use ‘foobar-build’ on the build side?  That
sounds weird.

In general, build systems only import (guix build …) modules on the
build side; things like (guix build-system …) modules (not to be
confused!) are meant to be used on the host side.

HTH,

Can the builder access channel code?

[Pierre Neidhardt]

Hi,

I'm working on a new build-systems from a channel.
When building a package using this build-system, I get

--8<---cut here---start->8---
building 
/gnu/store/j1qracwgv7qbxslbf6755z8wcwlv3bcf-foobar-qux-hires-2010.drv...
Backtrace:
   4 (primitive-load "/gnu/store/v4yp12m19g3bnn901kxa65xpifp?")
In ice-9/eval.scm:

   213:21  2 (_ #f)
   223:20  1 (proc #)
In unknown file:
   0 (%resolve-variable (7 . foobar-build) #)

ERROR: In procedure %resolve-variable:
Unbound variable: foobar-build
builder for 
`/gnu/store/j1qracwgv7qbxslbf6755z8wcwlv3bcf-foobar-qux-hires-2010.drv' failed 
with exit code 1
build of /gnu/store/j1qracwgv7qbxslbf6755z8wcwlv3bcf-foobar-qux-hires-2010.drv

`/gnu/store/j1qracwgv7qbxslbf6755z8wcwlv3bcf-foobar-qux-hires-2010.drv' failed
--8<---cut here---end--->8---

Here is the offending part:

--8<---cut here---start->8---
(define* (foobar-build store name inputs
#:key
(tests? #f)
(build-targets #f)
(phases '(@ (my-guix build foobar-build-system)
%standard-phases))
(outputs '("out"))
(search-paths '())
(system (%current-system))
(guile #f)
(substitutable? #t)
(imported-modules %foobar-build-system-modules)
(modules '((my-guix build foobar-build-system)
   (guix build utils
   ...
--8<---cut here---end--->8---

The default value of the key argument "modules" is the problem.  Is it
possible that the builder cannot find channel modules, or any module out
of the Guix tree?
