Support for Pylon 6

[roflmaostc]

Hi, thanks for the package, exactly what I need!

But, my machine has Pylon 6 installed

ls /opt/ | grep pyl        
pylon6

which somehow fails:

export LD_LIBRARY_PATH=/opt/pylon6/lib64                                                                                            [18-10-21 | 2:10:44]

Anything I'm doing wrong here?

Thanks, Felix

Hi Felix

Good to know the package is getting used.

Basler pylon unfortunately is not the greatest at binary compatibility. As a consequence, you currently need to have pylon 5.1(.0?) (first) in you LD_LIBRARY_PATH as this was the version pylon_julia_wrapper 0.3 (and 0.4) was compiled with - cf. the Dockerfile or build_tarballs.jl for the specific version number.

There will be a new version ready soon - end of October - with Julia 1.3+ (Julia 1.6/1.7 at least) compatibility.

Best regards, Jesper

[roflmaostc]

Yeah with /opt/pylon5/ it's also not working. Is it because I use Julia 1.6.3?

[stemann]

Quite likely. It’s only verified to work with Julia 1.0 (have been running like that in a container for a few years).

[roflmaostc]

Okay, that's unfortunate, I cannot make a clue from that stack trace.

I try PyCall since I anyway have to use that for a Thorlabs stage :cry:

[roflmaostc]

But I'm looking forward to the new version!

[stemann]

Will try to find time to finish the job earlier.

Struggling a bit to get a Julia 1.3/1.6-ready JLL built and tested, but at least the Julia 1.3/1.6 version of the underlying dependency has been ready for a while: https://github.com/IHPSystems/pylon_julia_wrapper/commit/993ae34a5838a2b2d680a2f7f32f555095da3afb
