Starting websockets transport fails #5

Closed Chartman123 closed 3 years ago

Chartman123 commented 4 years ago

Since a few days I can't get the latest ":master" Docker image running because of some missing symbols (lws_write_ws_flags).

  Starting Meetecho Janus (WebRTC Server) v0.10.6

Loading transport plugin 'libjanus_websockets.so'...,

I tracked it down to a change in the janus-gateway repository:

https://github.com/meetecho/janus-gateway/blob/4614b6b2b43031bcde457b9bd9b65e8a364d6f52/transports/janus_websockets.c#L1245

Is it possible that you're using an older libwebsockets that doesn't contain lws_write_ws_flags?

@Chartman123 the Docker image is using buster's version of libwebsockets (4.0). Upstream release 4.1, I'll try to manually download and use the updated version instead.

tranchitella commented 3 years ago

@Chartman123 would you mind trying the latest master and check if the problem persists?

Chartman123 commented 3 years ago

With the latest master image I get the following errors:

Loading transport plugin 'libjanus_websockets.so'...
[ERR] [janus.c:main:5306]   Couldn't load transport plugin 'libjanus_websockets.so': libwebsockets.so.16: cannot open shared object file: No such file or directory,
[FATAL] [janus.c:main:5368] No Janus API transport is available... enable at least one and restart Janus,

@Chartman123 would you mind trying again? In case it files, can you please share your config file?

Chartman123 commented 3 years ago

The latest image is running fine. Thank you for fixing it 👍

Chartman123 commented 3 years ago

Btw. are there any plans on providing versioned tags for the newer Janus versions, too, or was 0.9(.2) the last one?

tranchitella commented 3 years ago

@Chartman123 I published version 0.9.5 (latest of 0.9 branch) and 0.10.7 (latest stable release)

Chartman123 commented 3 years ago

Ok, thank you :) Does this 0.10.7 also include the fix for the websockets? Otherwise I will stick to master, which includes 0.10.8 iirc.

tranchitella commented 3 years ago

@Chartman123 yes it does, it is built using the same Dockerfile.
