Re: Blender has no denoiser

[Haider Mirza]

I ended up sending out a bug-report and giving my (almost working) 
packaged version of the dependancy to the epic people there.

Thank you for replying though.

Best of luck,
Haider

It was already sent in the CC'd issue. I think it's best to continue
the discussion there, instead of forking it onto two lists.

Re: Nix on Guix?

Thanks, Petr. I did add and update channels. I wonder if it's something simple, 
like needing to restart the system after installing Nix? I'll try again.

I had a similar issue in the past with blender, it was missing a dependency and 
I had to package it myself. It is what it is. Sometimes you need to package 
this kind of software, it's full of compilation errors and so on. The only 
thing we can do is to help you package it.
Can you share the package you developed?

Re: Nix on Guix?

Hi,

Hello Guix,
I'm trying to get the Nix package manager running on Guix. I followed the 
instructions at: 
 and 
successfully installed it, but trying to install and/or run any Nix 
applications gives me permission errors.
I installed for the 'guix-system'; should I have installed for 'guix-user'? Or 
do I need to add my user to some Nix-related group? Or have I done something 
else wrong?
best,
—Ben

I have nix-service running when I build my guix system and then I just run the 
following:

nix-channel --add https://nixos.org/channels/nixos-unstable
nix-channel --update

Instead of setting SBCL_HOME, could you try adding something like
'(push "/path/to/lib/sbcl/contrib/" asdf:*central-registry*)'
at the beginning of your "init.lisp" file?

As stumpwm doesn't use the sb-cltl2 contrib, it is not included in the
stumpwm compiled binary. But telling ASDF where it can find it and then
using '(asdf:load-system :sb-cltl2)' or '(require :sb-cltl2)' should
work.
If it doesn't, you could also try loading it directly with
'(load "/path/to/lib/sbcl/contrib/sb-cltl2.fasl")'.

stumpwm on guix - "sb-cltl2" issues

[Benjamin Slade]

I'm trying to run my long-standing stumpwm init.lisp on a recent Guix install, 
using the packaged stumpwm, however when it launches, it fails to process the 
init.lisp and gives me an "Don't know how to REQUIRE sb-cltl2." error.

I've set the SBCL_HOME variable both in .xprofile and in the init.lisp itself 
[via `(sb-posix:putenv "SBCL_HOME=/run/current-system/profile/lib/sbcl/")' ], 
but this doesn't seem to help.

Is there a good way around this? (On my other system I just compile stumpwm 
from source and install; I don't know if that makes a difference here.)

Blender has no denoiser

[Haider Mirza]

The Guix installation of Blender has no denoiser.
Blender's compositor says that Blender is compiled without 
"OpenImageDenoise"


Last time I checked OIDN (OpenImageDenoise) is free software and 
all it's dependancies are also.
I tried to packaged OIDN but it just ended up being a massive pain 
and It's depenadancy (ispc) just refused to compile.

Can you suggest some sort of solution (The IRC has no answers)

I guess you meant 'dependencies' where you said 'results'. So maybe run:

guix shell -D  -r 

...once to keep a profile with the dependencies registered as a root.
