Request for guidance on manual 10.9 build - RPi 4 #1907
Comments
Here are my guide for RPi 4, hopefully it is still valid: https://github.com/gobo-ws/misc/blob/master/OLA_install_RPi4.md |
thanks for your input, I will give this a shot! One question though, with these instructions would you expect the web interface to be available with olad once compiled and running? Thanks! |
I appear to be up and running now. Thanks! I'm not sure what exactly was out of whack. I added a few dependencies from your instructions (https://github.com/gobo-ws/misc/blob/master/OLA_install_RPi4.md) that I hadn't installed, then:
I'm not sure if it was the extra dependencies or the --enable-http or both, but I'm no longer stuck. Thanks! I'll redo everything from scratch later today so I have a setup that's reproducible but for now, all good, thanks again! |
I could really use some direction, I thought I was on the right track but now I'm not sure.
Here's what I'm trying to do,
I'm trying to use olad to confirm that my most basic setup is working before I dive any deeper with DMX. My setup is a raspberry pi 4 running raspberry pi os 64-lite, attached via uart/gpio to a dmx plug, that is in turn attached to a dmx cable and a dmx capable strobe light. I just want to be able to turn the light on/off to prove the hardware works before anything more advanced.
Here's where I'm at,
Initially I installed the ola package from the debian package repository. For raspberry pi os, that's still bullseye debian based, so it picked up ola 0.10.8. I got the web ui working but in the logs I saw the message:
... Failed to set baud rate to 250k
So I found the bugs / support tickets around that:
#1749
#1760
#1884
In particular I saw this message:
#1884 (comment)
So I tried to give building ola a shot.
Building 10.9 Attempt
I tried to install all the dependencies from the error in one big apt install but some of them could not be identified, at least python-protobuf python-numpy
So, I went back to #1884
and tried to use these instructions,
Following that, I installed packages as ./configure needed, although when I got to python-protobuf, I instead installed python3-pip followed by
pip install protobuf
which seemed to get me past the configure failure.
After all that it DID seem like I had ola:
It seems to run fine, but now I can't seem to get back to the Web UI. This is a headless install.
So, Questions,
dpkg-checkbuilddeps: error: Unmet build dependencies: python python-protobuf python-numpy
See below."If you built OLA with http support you can just use the web interface on http://localhost:9090" (source: https://www.openlighting.org/ola/getting-started/using-ola/ )
