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 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

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!

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 anylonger.
assuming the former (as the latter would require porting theexternal 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 requirethat
step. fgmasrd IOhannes _______________________________________________ Pd-list@lists.iem.at <mailto:Pd-list@lists.iem.at> mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list
