Hi Norman,
Merry Christmas :). I'm chilling and learning about Sculpt on this
holiday, hope you're also enjoying the day. No rush on getting back to me!
These are great helps.
Two things:
1. I think you meant 11.5 "bullseye"? 10.5 is "buster". I downloaded
11.6 as a base and will use that in a VM and once I get it working
there, I'll move back to my T430, running Mint 21.1 Vera. Also, it took
me a while to figure out the "cnuke's download_debian" note :). I'll
start with running it in Virtualbox 6.1 on my Mac. I have enough
learning to do without doing the VM stuff in Sculpt. I'll get there soon
enough, but not today.
2. When attempting to run ./tool/depot/download
genodelabs/pkg/x86_64/sculpt/2022-10-13, I get the following error. I
just redo the command and it looks like it picks up where it left off,
but I'm not sure it's actually ok. There are files in
depot/genodelabs/src/vim-minimal... What say you?
------------
download genodelabs/src/vim-minimal/2022-08-30.tar.xz
download genodelabs/src/vim-minimal/2022-08-30.tar.xz.sig
xz: (stdin): Unexpected end of input
tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now
make[1]: *** [/home/wsenn/genode/tool/depot/mk/downloader:45:
/home/wsenn/genode/depot/genodelabs/src/vim-minimal/2022-08-30] Error 2
------------
I'm continuing on, but thought I'd shoot this off in the meantime.
Thanks,
Will

Hi Will,
1. What distro (exactly) do y'all use - it says Ubuntu LTS in the
docs - so Ubuntu 22.04.1 LTS is the current version - is that it? I
have the luxury of picking whatever I like (thankfully, I'm a debian
user, so Ubuntu/Mint/Debian are fine with me)
I'm currently using Debian 10.5 (bullseye), downloaded via cnuke's
download_debian package.
2. If I want to change out the wifi firmware and edit the config
files, do I need to just tweak the files and build the bootable image
or do I need to do the build Sculpt from source thing?
Building the Sculpt image means building from source. However, you
don't need to compile everything from scratch. To fastest way would be
to first follow the steps "Building the boot image" based on the
binary packages published by Genode Labs [1], then only tweak the wifi
driver, and re-build the image (step 7). The following hints may
hopefully help you along the way:
1. Ensure that you have checked out Genode's 'sculpt-22.10' tag [2]
or a branch based on this tag. Personally, I keep my personal tweaks
of Sculpt on a dedicated branch [3]. This is important in order to
ensure that the source code you are using is consistent with the
official 'genodelabs' binary packages.
2. While working on the wifi driver, you can tell the build system to
build only this single component, not all of Sculpt. So you can
quickly catch compile-time errors.
build/x86_64$ make drivers/wifi
3. When finally rebuild Sculpt (step 7), tell the build system to
update the depot content (the binary packages Sculpt is made of)
as needed. You can do that by uncommenting the following line
in your build/x86_64/etc/build.conf
RUN_OPT += --depot-auto-update
Now, when issuing the 'make run/sculpt ...' command, you should
see the build system checking all the depot archives, and creating
a new version for the wifi-related things that you just touched.
After the build, check the git status and commit the changed
version hashes. So you can reproduce the exact same version later.
4. If you want to experiment with customizing Sculpt's components at
source-code level, you may find the additional documentation at [4]
useful. Personally, I love the 'build:' feature. When adding a line
like the following to repos/gems/sculpt/default-pc.sculpt, one can
prompt the build system to build this specific component and
integrate the result into the sculpt image. E.g.,:
build: server/nitpicker
In this example, the nitpicker GUI server gets built from source
and all other components are taken from the binary packages.
With the '--depot-auto-update' disabled, this creates the
customized image really quick (just a few seconds) and you don't
need to deal with updating depot archives at each iteration.
Maybe, this would work for your wifi tweaks as well, but I'm not
100% sure because the change may affect the list of firmware files.
Well, it's worth trying.
