I'm having an error when trying to deploy my Shiny app. It runs locally, but whenever I republish and try to access it through the link, within seconds the screen is greyed out and "Disconnected from the server" appears. I have looked through the logs and have this message:

/usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by /usr/local/julia-1.0.2/bin/../lib/julia/libLLVM-6.0.so)

My app uses Julia, so I'm wondering if the error is related to this. Does anyone know how I might go about fixing this problem?

Hi Alison,

Were you able to figure this out? May be having a similar problem, and there's not a whole lot of literature on this subject.

Thank you for reporting this, and I am sorry for the inconvenience.

The version of libc++ might be too old for Julia right now:

I will file an issue to track this, but no guarantees for a timeline.
