Error building OLA on Ubuntu

[p3k]

Hello

I am trying to build OLA on an Ubuntu machine. After installing two
missing devevlopment libraries (libprotobuf-dev and libcppunit-dev)
using aptitude I could successfully ./configure.

However, when executing make I got the following error:

Rpc.pb.cc: In copy constructor 'ola::rpc::RpcMessage::RpcMessage(const
ola::rpc::RpcMessage&)':
Rpc.pb.cc:143: error: base class 'class google::protobuf::Message'
should be explicitly initialized in the copy constructor
make[4]: *** [Rpc.pb.lo] Error 1
make[4]: Leaving directory `/home/tobi/Desktop/ola-0.8.1/common/rpc'
make[3]: *** [all] Error 2
make[3]: Leaving directory `/home/tobi/Desktop/ola-0.8.1/common/rpc'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory `/home/tobi/Desktop/ola-0.8.1/common'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/tobi/Desktop/ola-0.8.1'
make: *** [all] Error 2

Is this a bug in the OLA code or did I install the wrong protobuf
library?

Please let me know if you need additional information about my setup.

Ciao,
Tobi

See the thread "Issue 9 in boblight: OLA support" from 2 days ago.

Oh, that was easy.
:)

After I removed the -Werror from common.mk I was able to build and
install OLA.

Then I tried to build the ola-examples package to get ola-dmxconsole
but got another issue, probably similar to the -Werror one, please see
below.

What do I have to do to prevent “warnings being treates as errors”, as
stated in the log output?

Best,
tobi

Edit src/Makefile.am and remove -Werror. Then run autoreconfig &&
./configure again

Great, I did a grep for -Werror and got more than one occurrence but
was not sure which one to remove.

Anyway, that did the trick. Thank you!

Now how do I use ola_dmxconsole? When I just enter the command in the
shell I get an error:

$ ola_dmxmonitor -u 1
error: Connection refused

Do I first have to setup my machine as Art-Net node or the like? How
would I send Art-Net data to a certain IP address?

Cheers,
tobi

You need to have olad running and then patch a port. See

Okay, when I run olad I get debugging output, some of it look like
errors. (See below.)

(How) do I have to create the /dev/dmx0 device?

What about the /dev/ttyUSB0 device?

Ciao,

If you don't have any USB -> DMX devices you can ignore those.

[p3k]

Good to know.
:)

So ola_dmxconsole and ola_dmxmonitor are up and running now.

And now I see polls and data coming in on the iPad (but that’s the
other thread :)

Thanks again for your help!

Cheers,
Tobi

Cool! So what are you making? An Ios artnet viewer?

Sent from my iPhone :)

> Cool! So what are you making? An Ios artnet viewer?

Well, kind of. A viewer in regard of the iPad showing the mixed RGB
color of three channels.

So, all the device should do for now is acting like a huge pixel.
Approx. 16 of them then will be integrated in a bigger installation of
“real” lighting hardware controlled by corresponding proprietary
software which also sends the Art-Net data.

At least that is the plan.
:)

The installation is part of the Media Architecture Biennale 2010
taking place in Vienna, Austria, starting on October 7, 2010.

Maybe you are interested to come over for a visit?
