Hi everyone. I'm trying to make my DMX interface (Enttec OpenDMX USB) work with Pd. I read a lot of things about it, and probably the best way to make it work would be by using Open Lighting Architecture ( https://www.openlighting.org/ola/) I'd like to avoid using something like QLC if possible. I'm on Linux (Ubuntu).
I found this external http://puredata.info/Members/santi/ola2pd/ which seems to be perfect for me. I tried to follow all the steps (installing Ola, compiling Flext), but the object Ola2pd is not recognized by Pd. As they suggested, I tried to compile it myself by using Flext. It works, but still, the object Ola2pd is not recognized in pd. I received the message "undefined symbol: _ZTIN3ola6client17BaseClientWrapperE"
Any idea of what I could do? Do you know if some other externals exist for the job? Or if there's some other solutions for controlling a DMX Interface with Pd?
Thanks in advance if you can help

well, the problem you are facing is, that (at least) one of the symbols that are supposedly provided by libola is missing.
so there's two possibilities:
- either you are not (properly) linking against libola
- or current version of libola does not provide that symbol any longer.
assuming the former (as the latter would require porting the external to the new libola), i see that the readme.txt has an explicit note on "compiling on ubuntu", that requires you to repeat the linker command with "-lflext-pd_t -lola" *after* the output file (ola.pd_linux) rather than before it (because doing it in the wrong order will make modern linkers skip the linking; this is actually a bug in the buildsystem).
even if you are not using ubuntu, most modern linkers will require that step.

btw, if you are on a recent Debian based distribution, building might be as simple as:
$ sudo apt install pd-flext-dev libola-dev
$ make -f /usr/share/pd-flext/dev/Makefile.flext ldlibs="$(pkg-config
--libs pd-flext) -lola" SRCDIR=.
(that's two lines).

libola itself may have a number of deps: on my Debian system I get
$ pkg-config --libs libola -L/usr/local/lib -lola -lolacommon -lprotobuf
so maybe IOhannes's second line could be amended to:
$ make -f /usr/share/pd-flext/dev/Makefile.flext ldlibs="$(pkg-config --libs pd-flext) $(pkg-config --libs libola)" SRCDIR=.
?

good point.

$ make -f /usr/share/pd-flext/dev/Makefile.flext ldlibs="$(pkg-config --libs pd-flext) $(pkg-config --libs libola)" SRCDIR=.
you can add multiple packages to a pkg-config query, making both the command and the resolved library string a bit easier:
$ make -f /usr/share/pd-flext/dev/Makefile.flext ldlibs="$(pkg-config --libs pd-flext libola)" SRCDIR=.
and really, one should *also* get the cflags from pkgconfig, so the ideal command would be:
$ make -f /usr/share/pd-flext/dev/Makefile.flext
cflags="$(pkg-config --cflags pd-flext libola)"
ldlibs="$(pkg-config --libs pd-flext libola)"
SRCDIR=.

That's it! I didn't really understood the "compiling on ubuntu" part in the readme.txt file.
Especially this "You can copy the last command of the build.sh terminal output". I thought the code line was inside build.sh, but no, it's outputed on the terminal. So after this, my pd object ola2pd finally works! Thanks a lot for the hint! It doesn't mean I can control the lights yet, but it's already a big step!

Hello!
i am using a different solution to control DMX: i struggeled as well with enttecs openDMXusb and i am now using an
Enttec ODE (open DMX Ethernet) https://www.enttec.com/eu/products/controls/dmx-over-ethernet/ode-mk2-open-d...
This allows me to send Artnet-protocol commands via Ethernet directly from PD by using the netsend-objects.
Of course, one has to wrap his/her head around the artnet-protocoll, but marian weger did already and build some very nice vanilla-only abstractions,
[artnetout] [makeartdmx]
these can be found in his git within his kollabs-abstractions:
https://github.com/m---w/kollabs
maybe this helps?
The only drawback when using the enttec ODE: to configure it, the quickest way is to use enttecs own configuration software,which is win and mac...(i did not try using it via wine)
enjoy,
peter

Thanks for your solution. I finally didn't have to try it because I finally made the other solution I was working on work. Here is what I've done:
My main mistake was about compiling the ola2pd object with flext. in the readme.txt, there was a part I didn't understand first, so I skipped it : "For Ubuntu there is an aditional compilation step. Ubuntu's gcc has a option making buils.sh doesn't link correctly the OLA library. You can copy the last command of the build.sh terminal output and change the option -lola to the end of the command." That was the solution for compiling ola2pd, then after that the pd object worked perfectly.
Then I started OLA, and started configuring it here http://localhost:9090 The important part (and I lost a lot of time because of it) was to disable the "Enttec Open DMX Plugin" and "Serial USB Plugin", then enable the "FTDI USB DMX Plugin". I added an output device/port (called FT232R USB UART in my case), then after that I was able to control the lights by using the DMX Console / DMX Monitor (still in http://localhost:9090)
In Pd, the object ola2pd is really easy to use (see the help file) and does the same job as the DMX Console.
Done!

hello,
I used ola once or twice with pd. I configured it to receive OSC message so I did not need any externals...
Since your interface is the enttec dmx usb, you can also use an abstraction made by mrtoftrash@gmail.com, that is located in pd svn/hardware/DMXUSBPro It use zexy/length (that you can replace with list length) and comport. The rest is vanilla friendly.
