leads to:

--8<---------------cut here---------------start------------->8---
starting phase `check'

and I have no clue what I am missing.


The other part of the story is:

--8<---------------cut here---------------start------------->8---
    (arguments
     `(#:phases
       (modify-phases %standard-phases
         (add-after 'unpack 'delete
           (lambda _
             (delete-file-recursively "inst")
             #t)))))
--8<---------------cut here---------------end--------------->8---

leads to:

--8<---------------cut here---------------start------------->8---
starting phase `install'

and the addition of ’(mkdir-p "inst/doc")’ makes the build pass, but:

  file:///gnu/store/…-r-diffcyt-1.8.8/site-library/diffcyt/doc/index.html

shows one HTML link pointing to:

  file:///gnu/store/…-r-diffcyt-1.8.8/library/diffcyt/doc/diffcyt_workflow.html

which does not exist.


Another random example is ’r-ebimage’,

--8<---------------cut here---------------start------------->8---
$ tar xvf $(guix build r-ebimage -S) | grep "inst/doc"
EBImage/inst/doc/
EBImage/inst/doc/EBImage-introduction.R
EBImage/inst/doc/EBImage-introduction.Rmd
EBImage/inst/doc/EBImage-introduction.html

$ md5sum EBImage/inst/doc/EBImage-introduction.html  $(guix build 
r-ebimage)/site-library/EBImage/doc/EBImage-introduction.html

--8<---------------cut here---------------end--------------->8---

Well bit-to-bit identical HTML as upstream… strong evidence that the
documentation is not locally generated.  And the upstream-upstream

  https://github.com/aoles/EBImage/tree/master/inst

does not contains this HTML, AFAICT.


BTW, going via the Source Repository

   git clone https://git.bioconductor.org/packages/EBImage

i.e., ’git-fetch’ instead of ’url-fetch’ seems the right direction to
fix.  Because:

 1. it is the “real” source and this source is easily verifiable; for
 example it is easy to check the commit hash of the Bioconductor repo
 against the one of the upstream GitHub repo.

 2. the fallback to SWH works for git-fetch.  The tarball is not ready
 yet; and who knows when… :-)

All the best,
