Hi all and sorry if it's a FAQ !
I would like to write a package definition for a program that expects
openmpi < 4.0.0, which is present in earlier versions of guix. If I'm not
mistaken I have to use inferiors in that case, and I tried this :
(use-modules (gnu packages mpi)
(guix packages)
(guix download)
(guix build-system gnu)
(guix licenses)
(guix build utils)
(guix gexp)
(guix inferior)
(guix channels))
(define mychannels
(list (channel
(name 'guix)
(url "https://git.savannah.gnu.org/git/guix.git";)
;; Last commit that still has openmpi < 4.0.0
(commit
"1482531cd7d0f1f7e565207240affb68dd822e17"))))
(define myinferior
(inferior-for-channels mychannels))
(define myopenmpi
(first (lookup-inferior-packages myinferior "openmpi")))
(package
(name "coevol")
(version "1.5b")
(source (origin
(method url-fetch)
(uri (string-append "
https://github.com/bayesiancook/coevol/archive/refs/tags/v"; version
".tar.gz"))
(sha256 (base32 "112kjjxwlm9m3f3wks3q86gp561l8s5gsw17zrffrhljixd8qyyp"))))
(build-system gnu-build-system)
(arguments
(list
#:phases #~(modify-phases %standard-phases
(delete 'configure)
(add-after 'unpack 'chdir (lambda _ (chdir "sources") #t)))))
(inputs (list myopenmpi))
(synopsis "Correlated evolution of substitution rates and quantitative
traits")
(description "...")
(home-page "
https://megasun.bch.umontreal.ca/People/lartillot/www/downloadcoevol.html";)
(license gpl3+))
My problem is that when invoking guix I get this:
$ guix package --install-from-file=coevol.scm
Mise à jour du canal « guix » depuis le dépôt Git «
https://git.savannah.gnu.org/git/guix.git »...
Computing Guix derivation for 'x86_64-linux'... \fetching path
`/gnu/store/ir3092v7657h6g4g2vlsw3zrli3rndb3-zlib-1.2.11.tar.gz'...
substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0%
substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0%
and a spinning character for more than 10 hours. I can see a 'guix
substitute' process working and using quite some memory after a while (3-4
GB). My question is this: should I just be patient and wait for it to
complete or I'm doing this wrong?
Thanks for any hint!
Philippe.
