help with USB bluetooth driver

[Jesse Gibbons]

I recently purchased the device described here 



H-node says it should work without nonfree drivers. But when I plug it 
in, the kernel says non-free firmware was disabled. Do I need to setup 
anything to get the kernel to load the driver?


H-node says that it was tested on PureOS. I know that PureOS does not 
disable firmware, they simply don't install them on the distro by 
default and don't provide any way to install them. So this could be 
something for Purism to investigate.


I've searched the linux-libre source, including the deblob script, but I 
can't find where it disables that particular device, so it's safe to 
assume that it is not known to require blobs. Furthermore, the device 
itself is documented in the deblobbed source, so it's reasonable to 
expect the device to work.


I confirmed that lsusb -v is almost identical to what's on h-node, where 
the only difference is the serial number. I can't find the hwinfo 
package, so I can't compare the other data. What package contains hwinfo?


If I can get it to load on another gnu/linux-libre operating system, 
it's a problem with guix. Else it is a linux-libre bug and I should 
report it upstream. What linux-libre distro should I check?

I did reconfigure, but I didn't try removing and adding the printer
again.

It does appear to exist. Actually, I figured out how to successfully
print a document using ~libreoffice --headless -p test.odt~. So, I think
my printer problem is actually reflecting a problem with
system-config-printer.

Kyle,

I'd strongly recommend using the ‘real’ CUPS interface at 
localhost:631 over any third-party helper, but…

when I tried to click the administration tab.


I can confirm that the Administration tab freezes on my laptop and 
print server (CUPS proxied through nginx).  That's new :-/  I'll 
report a bug for that.

non-ascii char in mount-point name ?

[Fulbert]

Hi,

  In my Guix system configuration file, I have a
(file-system …  (mount-point "/mnt/raté"))
with a 'é' (U+00E9) in its name, which gives the following error when
trying to reconfigure :

system: error: invalid character `�' in name 
`shepherd-file-system--mnt-raté.scm-builder'


Did I miss something or is it a Guix limitation ?

I wouldn’t be surprised. On the other hand, it does not import other
extensions, such as hplip and foomatic-filters, either.

Did you run guix system reconfigure after adding the packages to
config.scm? Did you try removing and adding the printer again
afterwards?

Does a /var/guix/profiles/system/profile/lib/cups/filter/rastertoqpdl
symlink exist in your filesystem? I think you could try changing the
rastertoqpdl path defined in the system-config-printer configuration (or
CUPS configuration, assuming it’s just a CUPS GUI frontend) from
/gnu/store/… to that path. /gnu/store/ contents are volatile. Again,
just guessing; perhaps the path is hardcoded into the CUPS/splix build
and uneditable.

Hi WZ,

Thanks for following up.

Yes, it exists in the splix package, but not in the cups
package. Looking at the Guix source code I saw that
~system-config-printer~ (in ~guix/gnu/packages/gnome.scm~) takes input
from cups on build, but not from splix or other print drivers. Could
that be part of the problem?

The user is in the lp group. I didn't know about lpadmin. I will add
that group as well and see if it changes anything. The CUPS localhost
page was behaving strangely (stalling on load) when I tried to click the
administration tab. Thanks for the tip!

Re: Install older version of a package with the "@version" specifier

It is not easy to find the old revision (commit) which owns the
version you are looking for.  In such cases, the Guix Data Service
could help.  For example, this URL lists all the R versions in Guix
over the time:

https://data.guix.gnu.org/repository/1/branch/master/package/r

As you can see, it is rare that 2 versions of R exist at the same time
in Guix.  I let you click and you will find that the last commit
containing the R version 3.6.3 is the commit 899093.

https://data.guix.gnu.org/revision/89909327d017198969436237acc7c93823ff8147/package/r/3.6.3

Then the way for creating an inferior is "guix time-machine".  It goes
back but without polluting your current setup; you can have different
versions from different time/commit.  The following command creates
temporarily an old Guix version and use it for spawning an environment
containing R.

--8<---cut here---start->8---
$ guix time-machine --commit=899093  \

Instead of 'environment', you can use 'install -p
/path/to/profile/with/old/R'.  However, it is important to be clear
with which version of R you are using and which version is used to
"compile" the R packages you will install, and use a manifest.scm file
is really a good practise when traveling in time. :-)


Hope that helps,
simon

In general, at any point in time, we only keep one version of each packages. 
Exceptions are pretty rare (gcc, python, …). There two ways to get a version 
that's different from the one in the current guix:

- use the current guix and apply the recipe to an different version, by using 
something --with-source=r=r-3.6.3.tar.gz or similar. This is not guaranteed to 
work, as it applies the build procedure of version 4 to version 3. It uses 
recent software that are patched for vulnerability though.

- use r from an old revision of guix that had the version you're looking for. 
This can be done using an "inferior". The package will more likely build (and 
even have substitutes), but it uses the old version of all its dependencies, 
which are not necessarily patched for vulnerabilities and may require more 
space to be stored, as they are not shared with other packages.

HTH!

Thanks for the suggestion, WZ! I gave it a shot adding cups and splix
into my default packages. Unfortunately, even after completely

Install older version of a package with the "@version" specifier

[Lo Peter]

Dear all,

I am trying to install r version 3.6.3, where the current version is at 4.0.2.

Accordingly to the manual at
https://guix.gnu.org/manual/en/html_node/Invoking-guix-package.html it
should be possible to specify the package version such as "guix
package -i r@3.6.2", but on my guix (installed on slackware 14.2), it
says:
guix package: error: r: package not found for version 3.6.2

What am I missing here?

As a side note, the various guix-foo commands from guix/scripts/* have
an undefined return value so you can't check for #t or anything to see
if a package built.

This is because the regular binutils package was recently 'hidden' due
to an upstream bug, and 'binutils-gold' accidentally inherited the
'hidden?' property.

I fixed the inheritance in 4a13050b877f9058414f4b7633e423726e9bbb32, so
you should be able to install it (again) after a 'guix pull'.

By default, a dynamic version of bpftrace is built. However, as we do
not provide a libbpf.so, it falls back on libbpf.a.

There's a comment in FindLibBfd.cmake which says:

--8<---cut here---start->8---
# libbfd.a is not statically linked with libiberty.a or libz.a so we must 
manually
# do it. Furthermore, libbfd uses some libc symbols that we must manually
# link against if we're not using static libc (which includes such symbols).
--8<---cut here---end--->8---

So when STATIC_LINKING is ON, they add "libz" to the required
libraries. It would be preferable to avoid building a static bpftrace,
so I tried to provide a dynamic version of libbpf.

There's still a failure at validate-runpath phase that need to be
fixed, not sure why.

Thanks,

Mathieu

Yes, but provides something like:

(use-modules
 (guix store)
 (guix derivations)
 (guix packages))
 
(define (build-packages packages)
  (with-store store

Because otherwise, you need to know "package-derivation" and
"build-derivation" and where they are (I run 'ag' or 'git-grep'
to find them which is not handy).  And for example, I knew it was
possible but it was not "obvious". :-)

One way to do this with the guix API is to get the derivation, then build it:

(use-modules (guix derivations) (guix store) (gnu packages bash))
(define package bash-minimal)
(define store (open-connection))
(define der (package-derivation store package))
(build-derivations store (list der))

Is that what you want?

Well, I do not know enough the API but it should be added and exposed if
it does not exist yet.  And the question is which level of granularity?
