You mean the project's license is not part of this list [1], right?

[1] https://www.gnu.org/licenses/license-list.html


Otherwise, I do not have the answer for your question. :-)

Does the '#' at the beginning mean that your are running as root?

Well, I find easier 1/ to log in as 'emederna' user and 2/ to run

  guix build -L ~/src/packages asiofi

>From my understanding, there are 3 "issues":

 a) instead of create a full new package for libfabric, you could
update the Guix one or use 'inherit', e.g., (not tested)

(define-public my-libfabric
  (inherit libfabric
     (version "X.Y")
     (source blablabla)))

 b) missing '#t' to the phase 'add-before'

 c) missing the package 'pkg-config', i.e.,
       #:use-module  (gnu packages pkg-config)
and
    ("pkgconfig" ,pkg-config)
in the list of inputs.


Now, it seems compiling on my machine. :-)


Hope that helps.
