Server mode seg faulting on Ubuntu #132

Closed PaulHax closed 10 months ago

PaulHax commented 10 months ago

Description

When I run Agave with the --server option, I'm getting a Segmentation fault (core dumped). GUI runs fine when starting Agave without --server.

Kind of a personal problem, but perhaps folks have suggestions.

Command line output

/agave/build$ ./agave --server

Are you building from current main branch or from a tagged release?

toloudis commented 10 months ago

The place where the error is being written is still in the middle of websocket server initialization, possibly related to where it looks for TLS certificates. That code hasn't been exercised very much and hasn't been changed lately. I'll do a fresh linux build today and see if I can repro here.

Here's what you should roughly expect to see on linux:

I'm building from branch main. Thanks for the tips.

toloudis commented 10 months ago

One more tip for now, check the Dockerfile for more thorough batch of linux dependencies to install.

toloudis commented 10 months ago

@PaulHax did you have any luck with this?

PaulHax commented 10 months ago

The Dockerfile builds and runs server mode just fine for me. Which is scratching the itch with minimal contortions for my development, for now.

Thank you for the help!
