Error when building from source

Hey there, thanks for trying it out.

Which version of Pylon are you using? It does not seem to find the libraries, which is odd.
And you are right about GLFW. As it is stating at the end, it does not find the Xrandr dev package. You can either install them using conda, or simply do it system-wide (apt-get) -- does not usually harm you. Not sure how you would install that on Ubuntu, but I'm sure Google will know. If you wish to use conda for that, here are a couple ones you can install on linux (conda-forge required):
https://anaconda.org/conda-forge/libxrandr-devel-cos6-x86_64 (or also without the devel if it doesnt suffice)
Same for other libraries that might come up (-cos6... are the libraries specifically for your system)
https://anaconda.org/search?q=xcursor

Hi Tristan - yep, doing sudo apt-get install xorg-dev libglu1-mesa-dev solved that issue.

However, now I have issues with it not detecting the Pylon installation:

I currently have installed Pylon version 6.1.1. I also tried uninstalling it and reinstalling version 5.2.0 (as you tested it according to the documentation), and then the error is slightly different:

[ 84%] Linking CXX executable ../../../trex_check_python

Thanks,

Whats your output for ls /opt/pylon5/lib64? I assume I am missing some library names in the Application/src/commons/CMakeModules/FindBaslerPylon.cmake. I can add those easily.

It's also still missing libuuid-dev apparently.

[elhananby]

I've installed libuuid-dev with sudo apt install uuid-dev.

The output of ls /opt/pylon5/lib64 is attached..

Alright, you may try pulling the newest version using git pull from the master branch and see if it finds your libraries now!

[elhananby]

I'll have to check it tomorrow and will keep you updated.
Thank you for all the quick help!

[mooch443]

No worries! You can edit the file yourself, too, in case it does not work. It's pretty straight-forward (just add more names to the existing lists of names). But do let me know!

Hi Tristan, I just had time to check it again today, but it seems everything's working now.
Thanks for all the help!
