How to use gexps in builds?

How to use gexps in builds?

[nly]

...
(build-system trivial-build-system)
`(#:modules ((guix gexp))
         #:builder
         (gexp->derivation "gnumake"
                           #~(begin
                               (mkdir #$output)
                               (chdir #$output)
                               (symlink #$gnu-make #$output)))
         ))
...

The above form looks like it asks for too many (use-modules ...) (6 or
even more). What am I missing?

Hi,

It’s not possible yet to use gexps here, but there’s a
‘wip-build-systems-gexp’ branch that’s about making it possible.

When it becomes possible (hopefully soonish), you’ll write something
like:

  (build-system trivial-build-system)
  (arguments
   `(#:builder ,#~(begin …)))

HTH!
