Hi Guix,
I try compile to Arduino plataform using Microscheme (installed with:
guix package -i microscheme) on GuixSD, but there are errors.
I did:
sudo microscheme -m UNO -d /dev/ttyACM0 -au lightom.ms
Errors:
...
>> 32 lines compiled OK
>> Assembling...
avr-ld: cannot find crtatmega328p.o: No such file or directory
...
avrdude: Device signature = 0x1e950f
avrdude: reading input file "lightom.hex"
avrdude: can't open input file lightom.hex: No such file or directory
avrdude: read from file 'lightom.hex' failed
I have avr-gcc avr-libc avrdude avr-binutils avr-toolchain installed.
Thanks,

This is unrelated but I recommend not using “sudo” here. You can add a
udev rule to your system configuration to change the ownership of
/dev/ttyACM0.
For my AVR programmers I have this in my system configuration:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(define avrispmkii-udev-rule
(udev-rule "90-avrispmkii.rules"
"\

# Atmel Corp. Dragon
ATTR{idVendor}==\"03eb\", ATTR{idProduct}==\"2107\", MODE=\"660\", GROUP=\"dialout\"

This is a bug in our AVR toolchain. The internal search path for these
files appears to be wrong. What I did was copy the “crt*.o” file I
needed to my working directory. Maybe you can send an email to
bug-guix@gnu.org to report this as a bug?

You only need “avr-toolchain” as it contains all the other packages.

Should we add this as an optional service or to the default set of udev
rules?

I don’t think this should be the default. This rule is only useful for
those who own one of Atmel’s USB programmer devices. There is a
multitude of programmers for AVRs and users may want to use different
rules for different devices.
However, I’ve been wondering if we shouldn’t introduce nicer
abstractions for udev rules and make loading them a little less verbose.
It’s a bit unfortunate that while on other systems users are often told
to just dump a file somewhere in “/etc” to make device access work
without root on GuixSD it’s quite a bit more involved to achieve the
same.
Our documentation is also a little lacking in this respect. The manual
has very little to say about the “udev-service” and how to extend it (or
any of the other services, really), making it hard for users coming from
other systems to find where they need to change something to make the
udev rules work that they were told to add somewhere.
Here’s an idea, which might be bad: how about adding a feature to load
and merge a directory tree of configuration files as they are? For
example, if I had a directory “/etc/guix/system/udev/rules.d” then all
files therein would automatically be considered part of the system
configuration, maybe after adding “/etc/guix/system” as a prefix path to
some new field in the “operating-system” declaration.
I have a feeling that this will be considered a bad idea, but it also
seems to me that it would make the configuration of some parts of the
system easier than embedding file contents as strings in variables in
“/etc/config.scm” and modifying services manually.

Yeah, it doesn’t support the quick-hack style of doing things, which can
be frustrating.

It’s a bad idea! :-)
Seriously, I think having a directory that is automatically picked up is
a bad idea in the sense that it would defeat one of the main goals of
GuixSD, which is to support reproducibility. The hypothetical
/etc/guix/udev directory would not be controlled by GuixSD, so rolling
back wouldn’t be enough to return to the previous state, copying the
GuixSD config file wouldn’t be enough to duplicate the system state on
another machine, and so on.
However, what we can do is improve the interface. Things that come to
mind:
1. Change or remove the ‘udev-rule’ procedure; we should be using
file-like objects instead, so one could store them alongside
config.scm and write:
(local-file "./my-udev-rule")
2. Add a ‘extra-udev-rule’ procedure that you could use like this:
(operating-system
;; …
(services (extra-udev-rule (local-file "./my-udev-rule"))
…))
thus avoiding the verbose ‘modify-services’ stanza.
3. (Instead of #2) Introduce a ‘udev-rules’ field in
‘operating-system’, just like we do for firmware.
WDYT?
I don’t deny that this is still more heavyweight than dropping a file in
/etc. We should think about other ways to improve on that (what would
be the equivalent of C-M-x for GuixSD?), but for now it’s the only way I
can think of to preserve reproducibility.

These files are not loaded at system runtime but upon running “guix
system reconfigure”. Their contents *at that time* would be embedded in
the configuration. Their state *at runtime* would not matter (just like
the contents of “config.scm” don’t matter at runtime).
The files would become part of the configuration in the store. Changing
them would always require the additional step of reconfiguring the
system.

Is this really so different from the bad idea I proposed? As soon as we
load files outside of “config.scm” users would need to copy more than
just the GuixSD config file to duplicate the system state on another
machine. In this example we would need both “config.scm” and
“my-udev-rule” in the same directory.
The bad idea still requires a user to tell Guix to load udev rule files
from somewhere. The difference is that instead of loading files
individually by name it would load *all* rules from the directory.
I guess it’s not very different form what you propose in #3, actually.

I don’t know. Although this would simplify configuration I don’t really
like either of them for somewhat conflicting reasons. #3 gives special
treatment to udev rules (“What about Xorg config snippets?”), and with
#2 it seems like an unnecessary implementation detail that this
“extra-udev-rule” procedure is inside of the “services” field (“How come
this is a service?”).
I also feel that we should avoid adding “special” syntax. Actually, I
really like how generic this whole “modify-services” business is. It’s
just a little too verbose to be user-friendly, in my opinion.

OK, I had misunderstood your suggestion. It doesn’t have the drawbacks
I mentioned.
However, I don’t like the idea of having special directories that are
automatically scanned. In my mind, it’s a problem similar to “macro
hygiene”: we should not scan files whose name does not appear in
config.scm.

It’s similar to your idea, except that the file is explicitly named in
the <operating-system> object.
If that helps, we could also allow users to specify a directory
containing several rules, instead of just a single rule:
(local-file "./my-udev-rule-directory")
>> 2. Add a ‘extra-udev-rule’ procedure that you could use like this:

I sympathize with that.
In fact, <operating-system> translates to a <service> graph. The whole
<operating-system> thing is just “syntax.”
I would like to have a more formal way to describe this translation. I
think this would allow us to fearlessly add or remove fields to
<operating-system>. But I don’t know how to achieve it.
In the meantime, we should still address the usability issue that you
raised, which is why I made these suggestions.
Thoughts?
Thank you,
Ludo’.

It works. I think a good solution as optional service now.
