Not functional on Ubuntu 18.04 (linux)

[urlicht]

• With Ubuntu 18.04, Julia 1.5.3 (also tried 1.5.0), the package does not work (please see below for the trace).
• Running spinview application (the qt gui app that's shipped with the SDK works fine)
• I can also compile the example C sources that came with the SDK
• the camera interface is USB3, and it works fine on the Windows environment (same computer, same camera, Julia 1.5.3)

@urlicht can you try pkg> add Spinnaker@0.1.11 and see if that works? Meanwhile I'll look into the stacktrace

[IanButterworth]

I was assuming you're on 0.1.12, is that true?

[urlicht]

• Yes, I was on 0.1.12
• I kept downgrading the package version, and it seems like 0.1.9 works ok
• When I tried with 0.1.11 and 0.1.10, I got a different warning saying that the SDK cannot be found:

  [ Info: Precompiling Spinnaker [8e0d2ad3-56b8-53f3-8036-54b674872bef]
  ┌ Error: Spinnaker SDK cannot be found. This package can be loaded, but will not be functional.
  └ @ Spinnaker ~/.julia/packages/Spinnaker/dje6U/src/Spinnaker.jl:71

[urlicht]

FYI, just tried the latest Spinnaker SDK (2.3.0.77) on a different machine, and I still get the same errors

[IanButterworth]

Sorry @urlicht this slipped my mind. Before I fix it, a work around is to move to julia 1.6-beta1 or nightly. Or to roll back Spinnaker.jl

Hi Ian,

After successfully directing Spinnaker.jl to the correct locations for the Spinnaker API, I got the same pointer/tuple related error on Windows on ccall.

Thanks, Matt

[IanButterworth]

@matthewewreed sounds like you're not using julia 1.6. I recommend upgrading as it will fix this issue and it's likely to be an LTS julia version

[matthewewreed]

You've forced me to be a slightly more sophisticated user than I was yesterday, and I thank you for it! Thanks for all the hard work on this project. You've freed me from my last matlab dependency.

Thanks again, Matt
