you can provide constrains like what packages you are interested in and (optionally) their version numbers, compiler flags, etc.
then there is a sat solver (they call it concretizer) that provides a solution to the constrains. This solution is saved as a *.lock file. From a lock file you can reproduce the environment.
packages can also provide their own constraints. as in: "version x of this package needs gcc >= 9"
Is the sat solver determistic ? I’ve used them before and they were seldom determistic when things got computationally expensive . Very interesting . | 22:24:48 |

| elzair | Hey, I am having trouble running the following python script using nix-shell to get dependencies:
I get the following error:
Traceback (most recent call last):
File "/home/elzair/Development/python/./nixtest.py", line 4, in <module>
gi.require_version('Gtk', '4.0')
File "/nix/store/gwq3inwc86axcxb82jpwkzci3hjpw1xd-python3.10-pygobject-3.42.2/lib/python3.10/site-packages/gi/init.py", line 126, in require_version
raise ValueError('Namespace %s not available' % namepsace)
ValueError: Namespace Gtk not available | 18:31:14 |
| elzair | What might be happening? | 18:31:21 |
| elzair | The script is pretty simple:
#! /usr/bin/env nix-shell
#! nix-shell -i python -p gtk4 python310 python310Packages.pygobject3
import gi
gi.require_version('Gtk', '4.0')
from gi.repository import Gtk
def on_activate(app):
win = Gtk.ApplicationWindow(application=app)
win.present()
app = Gtk.Application()
app.connect('activate', on_activate)
app.run(None) | 18:32:15 |

 atemu12 | Huh, why's it picking up extra-utils as not-reproducible when the file actually belongs to util-linux? | 14:14:00 |
| atemu12 | Shouldn't its derivation have failed the check before that? | 14:14:29 |
| atemu12 | Or is it actually the fault of extra-utils processing? | 14:15:04 |

Huh, why's it picking up extra-utils as not-reproducible when the file actually belongs to util-linux? there seems to be an extra symbol or ordering is random dcgettext@GLIBC_2.2.5 | 12:59:56 |
| atemu12 | Yeah, the extra symbol confuses the heck out of me. | 13:29:36 |
