Hi,

Here an example to reproduce.  Everything is fine with the full path…

  #:use-module (guix packages)
  #:use-module (guix build-system gnu)

  (package
    (name "hi")
    (version "2.10")
    (source (origin
              (method git-fetch)
              (uri (git-reference
                    (url "https://example.org/hello-example.git")

ice-9/boot-9.scm:1669:16: In procedure raise-exception:
Wrong type (expecting string): #f
--8<---------------cut here---------------end--------------->8---

The reason is from ’package-field-location’ in (guix packages):

--8<---------------cut here---------------start------------->8---
     (catch 'system-error
       (lambda ()
         ;; In general we want to keep relative file names for modules.
         (call-with-input-file (search-path %load-path file)
--8<---------------cut here---------------end--------------->8---

the ’search-path’ returns #f.  Somehow, the %load-path should only
contain absolute paths and here it is not the case.  Therefore, the fix
should be in (guix build):

--8<---------------cut here---------------start------------->8---
(define %standard-build-options
  ;; List of standard command-line options for tools that build something.
  (list (option '(#\L "load-path") #t #f
                (lambda (opt name arg result . rest)
                  ;; XXX: Imperatively modify the search paths.
                  (%package-module-path (cons arg (%package-module-path)))
                  (%patch-path (cons arg (%patch-path)))
                  (set! %load-path (cons arg %load-path))
                  (set! %load-compiled-path (cons arg %load-compiled-path))
--8<---------------cut here---------------end--------------->8---

For instance using ’canonicalize-path’.


All the best,
simon

Indeed.  Fixed in 9a38bed2cf32e9462badfa43e74cdd4580e804fc.

Thanks!
