Packaging a simple Guile library

Packaging a simple Guile library

[sirgazil]

Hi,

I created a private Guix channel to experiment with packaging and started with a simple Guile library whose source looks like this:

#+BEGIN_EXAMPLE
guile-lab
├── doc         ← Texinfo doc
├── glab        ← The library
├── glab.svg
├── locale
├── packages    ← Has .scm files
├── README.org
├── scripts     ← Has .scm files
└── tests       ← Has .scm files
#+END_EXAMPLE

I thought using the "guile-build-system" would make this straightforward, but it didn't work as I expected. I was hoping to say, "Hey, guile-build-system:"

1. "glab" is the library you should build and install.
2. "doc" is the texinfo documentation you should build and install

But this build system compiles every scheme file in the source, which results in a build failure in the case of my package, and the documentation it installs is just the README file, not the info documentation.

leoprikler suggested me on #guix that "In that case you'll need one phase to (invoke "makeinfo" ...) and you'll also have to wrap the build and install phases in directory excursions".

So far, I've tried modifying the build phase as follows:

#+BEGIN_SRC scheme
(arguments
 '(#:phases
   (modify-phases
    %standard-phases
    (replace
     'build
     (lambda args
       (with-directory-excursion
        "glab"
        (apply (assoc-ref %standard-phases 'build) args)))))))
#+END_SRC

This fixed the initial package build failure, but now the build phase fails like this:

#+BEGIN_EXAMPLE
ice-9/boot-9.scm:752:25: In procedure dispatch-exception:
no code for module (glab i18n)
process '/gnu/store/1mkkv2caiqbdbbd256c4dirfi4kwsacv-guile-2.2.6/bin/guild guild compile -L . -o /gnu/store/318q4snsz936zblwgya0m027f6zwpadj-guile-glab-0.1.0/lib/guile/2.2/site-ccache/./farewells.go ././farewells.scm -Wunbound-variable -Warity-mismatch -Wformat ' failed with status 256
#+END_EXAMPLE

So it seems I need to make the "glab" modules available in the build phase for the modules to compile, but I couldn't figure out how.

Any help welcomed :)

The #:not-compiled-file-regexp option allows you to specify files not to
compile.  Let me know if it works for you.

Ah, that part is missing from the build system, we should probably add
it.  In the meantime, you can add a custom phase, as you wrote.

HTH,

Yes, that did it! I could build and install my package successfully.

I'll leave this for another version of my package.


Thanks a lot, Ludovic :)
