Building nimble for Guix: /bin/sh Could not find command

[trev-dev]

This is definitely an edge case, but I'm out of ideas and need to ask questions.

I am trying to build nim and nimble to Guix. The current package (and the one I am working on) currently can only seem to build the nim compiler.

Choosenim would be a nice option but it seems to fail at finding dependencies as well.

Like Nix, Guix builds packages in a contained environment. I have patched all of the shebangs, and swapped out hard-coded references to /bin/sh to the canonical path.

I have tried symlinking bash to /bin/sh in the build environment, which it simply will not let me do :)

I have tried exporting my $SHELL as the canonical path to /bin/sh. the end result is the same: we compile nim, then fail to compile koch with nim:

c_code/2_2/stdlib_browsers.nim.o c_code/2_2/@mnim.nim.o -ldl -lm -lrt

If it's at all meaningful to whomever may view this, I can show you what the build script is doing so far:

(modify-phases %standard-phases
  (delete 'configure) ; no configure script
  (add-after 'unpack 'patch-installer
    (lambda* (#:key outputs #:allow-other-keys)
      (let ((out (assoc-ref outputs "out")))
        (substitute* "install.sh" ; Patch install destinations
          (("/usr/") (string-append out "/usr/"))
          (("/etc/") (string-append out "/etc/"))
          (("/opt/") (string-append out "/opt/")))
        #t)))
  (add-after 'patch-source-shebangs 'patch-more-shebangs
    (lambda _
      (let ((sh (which "sh")))
        (substitute* '("tests/stdlib/tosprocterminate.nim"
                       "tests/stdlib/tstrscans.nim"
                       "lib/pure/osproc.nim")
          (("/bin/sh") sh)) ; patch static references to /bin/sh
        (substitute* (find-files "c_code" "stdlib_osproc.c")
          (("\"/bin/sh\", 7") (format #f "~s, ~s" sh (string-length sh)))))
      #t)) ; These don't show up in grep (anymore?) Maybe not necessary
  (replace 'build
    (lambda _
      ;; Fix the non-existant XDG cache problem
      (setenv "XDG_CACHE_HOME" "./cache-home")
      (mkdir-p "./cache-home")
      ;; Start building stuff
      (invoke "sh" "build.sh")
      (invoke "./bin/nim" "c" "koch") ; <-- we fail here
      (invoke "koch" "boot" "-d:release")
      (invoke "koch" "tools")
      #t))
  (replace 'install
    (lambda* (#:key outputs #:allow-other-keys)
      (let ((out (assoc-ref outputs "out")))
        ;; Hopefully install the things.
        (mkdir-p (string-append out "/usr/bin"))
        (invoke "./install.sh" (string-append out "/usr/bin"))
        #t))))

Could anyone shed some light on which aspect of bin/nim c koch is trying to call /bin/sh directly?

Look into osproc and poUseShell, it's likely that koch.nim ends up using this somehow.

[trev-dev]

I can't seem to grep poUseShell, but there seems to be many process related functions in osproc. My script already patches hard coded instances in osproc, let's see what I can find.

Looks like upstream has moved on without me! Closing.
