That seems fine.  I don't know what every single one of them does, but
all of the main ones are present.

The ones complaining about missing /dev entries are nothing to worry
about - those are plugins just looking for hardware that isn't there.
They can be disabled in files in ~/my-ola, but by default, it will
search for every kind of device.

The one that I don't know the meaning of is the IPV4Address.cpp:89
error.  I will ask about that.

According to this page, http support is an optional build option.  I
wasn't aware of that, but it would be convenient to enable.

  https://www.openlighting.org/ola/getting-started/using-ola/#How_to_setup_an_interface

To enable it, it needs libmicrohttpd.  It looks like guix has a package
for that - nice!

Thank you,

I found this to solve the memory issue, so I can build the package now:
https://github.com/OpenLightingProject/ola/issues/1103

Thank you for your help.  I am now working on some other issues with the
package and hope to post a patch soon.

Re: [PATCH] gnu: Add ola.

[John J Foerch]

Hi all,

I have made some progress with the ola package, but have run into
difficulty related to python used in its test phase.  Relevant code and
logs can be found here:

  The package definition: http://retroj.net/scratch/ola-guix/ola.scm

  The build log: http://retroj.net/scratch/ola-guix/ola-guix-build.log

  OLA's config.log: http://retroj.net/scratch/ola-guix/config.log

  Log of the test suite errors:
  http://retroj.net/scratch/ola-guix/test-suite.log

The ./configure argument --enable-rdm-tests turns on some tests that use
python.  These tests require the python-protobuf package.  Config.log
shows that protobuf was found, by whatever means autoconf uses to find
it, but the tests fail with this:

  File "/tmp/guix-build-ola-0.10.2.drv-0/ola-0.10.2/python/ola/PidStore.py",
     line 27, in <module> from google.protobuf import text_format
  ImportError: No module named 'google'

  ...

  File "/tmp/guix-build-ola-0.10.2.drv-0/ola-0.10.2/python/ola/rpc/SimpleRpcController.py",
    line 18, in <module> from google.protobuf import service
  ImportError: No module named 'google'

(For the complete messages, see links above.)

My best guess is that when the rdm tests run, PYTHONPATH does not
include whatever directory the google.protobuf module is in.  Anybody
know what's going on here?

Thank you,

[PATCH] gnu: Add ola

[John J Foerch]

[-- Attachment #1: Type: text/plain, Size: 628 bytes --]

Hello,

Here is a package definition for ola (Open Lighting Architecture).  I
was having trouble getting ola's python bindings to build, as detailed
in an earlier message, so this patch does not include them.  I intend to
add them when I figure out how, but since they're not essential to the
function of the library, I think they need not block adding the basic
package.  Ola also provides bindings for java, but they depend on Apache
maven, which we don't seem to have a package for yet, so here again, I
think that this can be added later.

Please let me know of anything that should be changed.

Thank you,

The patch builds on my machine and lgtm. I make some minor changes (in
diff format):

1. Add ola.scm to gnu/local.mk, so that the build system knows the
   presence of gnu/package/ola.scm. The commit message should say this
   as well.

2. Move protobuf from propagated-inputs to inputs. I don't know if this
   is right. But usually library depedencies don't need to be propagated
   (?), only command line tools needed at run-time need to be
   propagated, right?

3. Remove make-flags and phases. %standard-phases is the implicit
   phases, so there is no need to specify it. I think PREFIX is already
   handled by gnu-build-system. So it is not needed.

Perhaps this could be added to something like automation.scm?
Or iot.scm?

Makes sense to me, unless there are many other OLA-related packages.

John: could you send an updated patch incorporating suggestions from
Alex and Marius?  The rest LGTM.

Thanks!

How about lighting.scm?  There are a few other lighting programs that
could potentially be packaged.

Hello,

Thank you for taking a look and for catching those details.  Protobuf as
a propagated input is correct however - it is needed for 'pkg-config
--libs libola'.

I attached the patch with some modifications for your review.
I compiled and installed the ola package correctly.

John, how I can make a real test to see if it works?


Thanks

Hi Rene,

Thank you so much for doing this.  If 'make check' succeeds, those are
the main tests, but to check installation, I would look for the
following programs being installed:

    ola                   ola_e131        ola_plugin_state   ola_rdm_set
    ola_set_priority      ola_trigger     ola_uni_name       ola_artnet
    ola_dmxconsole        ola_patch       ola_rdm_discover   ola_recorder
    ola_streaming_client  ola_uni_info    ola_uni_stats      olad
    ola_dmxmonitor        ola_plugin_info ola_rdm_get        ola_set_dmx
    ola_timecode          ola_uni_merge   ola_usbpro         ola_dev_info

These are the programs installed by the Debian ola package, and I don't
know what packaging options might have affected which were installed,
but the list should be more or less the same.

To start the ola daemon and generate a config:

    olad -c ~/my-ola

This should start a web service on port 9090, so you can point a web
browser to localhost:9090 and see if anything comes up.

To connect the dummy device,

   ola_patch -d 1 -p 0 -u 0

Universe 0 should then be listed in both the web interface and in:

   ola_uni_info

If those things work, the only remaining thing to test is actual
hardware control, but we would be in pretty good shape.

Thanks again.
