working on raspberry pi 3

[mike_bee]

I got laser shark up and running with pretty good results on a raspberry pi 3. I was even able to use Openlase (minus the image tracing features) with good results.

Here is a link to some test results on a glow-in-the-dark tile using the Lasershark displayimage script.

Apologies Mike, it seems my forum notifications didn't work for this post.

Glad to hear it is working well with the pi 3. It certainly is a little faster than the 1st gen one, isn't it?

Ah and I see you found the image display app too! I've been wanting to try that with a phosphor screen but haven't had the time (I just used a long exposure feature of my camera when testing the app). Looks neat!

@mike_bee
I just started working on getting LaserShark up and running, and have run into the issue of compiling openlase for a Raspberry Pi.

If it's not too complicated, how did you go about removing the image tracing features to get it to compile?

You will need to modify the tools/CMakeLists.txt to comment out the lines that build this as so:
https://github.com/marcan/openlase/blob/master/tools/CMakeLists.txt

Afterwards delete your build directory and re-run through the build steps :)

Thanks, but that's already commented out.

I found that I could disable tracer by editing openlase/CMakeLists.txt and changing the Y to N in this chunk:

Code Select Expand

if(NOT DEFINED BUILD_TRACER)
  set(BUILD_TRACER "Y" CACHE BOOL "Build the image tracer (x86 only)" FORCE)
endif()

Problem solved!

(Now I just have to learn how to use it...)
