Subject: License Problem and Other Questions defining new package Geant4 from CERN for Partical Physcis Simulation
Date: Thu, 18 Feb 2021 15:04:49 +0800 (CST) [thread overview]
Message-ID: <2f9e6f18.1e53.177b3f49f09.Coremail.njuemail@126.com> (raw)
Dear developers at Guix,
I am a physics student willing to use the Geant4 simulation toolkit from the European Organization for Nuclear Research (CERN).
https://geant4.web.cern.ch/
The Geant4 code is distributied under its own licence, Geant4 Software License Version 1.0.
https://geant4.web.cern.ch/license/LICENSE.html
Let's call this license G4SL1.0. After some searching, finding it is NOT listed by FSF or GNU in their license list.
https://www.gnu.org/licenses/license-list.html
But from a personal perspective, G4SL1.0 do seems like a free software license.
So, may it be included into the Guix proper (gnu packages)?
I am currently testing the package under a custom channel,using cmake-build-system.
https://git.nju.edu.cn/nju/chngix/-/blob/master/gix/packages/geant4.scm
Here is another problem:
during configuring command "cmake" on a non-Guix system,
-- Geant4 has been pre-configured to look for datasets in the directory:
-- /usr/local/share/Geant4-10.7.1/data
the user needs to download datasets and unpack them under that directory.
https://geant4.web.cern.ch/support/download
Or, set flag -DGEANT4_INSTALL_DATA=ON to automatically download the datasets during building.
On Guix however,
-- Geant4 has been pre-configured to look for datasets in the directory:
-- /gnu/store/byprhqa1qq6s0ksgdpjgwv58ak25kprd-geant4-10.07.p01/share/Geant4-10.7.1/data
the building process is sandboxed, and does not allow download during building that causing non-repuduciable build result.
Cmake flag GEANT4_INSTALL_DATADIR defaults to "share", a path relative to CMAKE_INSTALL_PREFIX,
and it can be set to define the directory storing datasets other than ....../share, but datastes should always be under "GEANT4_INSTALL_DATADIR/Geant4-10.7.1/data".
https://geant4-userdoc.web.cern.ch/UsersGuides/InstallationGuide/html/installguide.html#geant4buildoptions
But the (source origin) denotes "a file" only,
https://guix.gnu.org/manual/en/html_node/package-Reference.html
is it possible to define a package fetching multiple files and extracts them into the desired directory, using the Guix package definition?
I am not familiar with trivial-build-system.
The build and install of the geant4 without datasets using cmake-build-system seems to be successful.
Your help would be much appreciated.
With best regards,
Sebastian
