linux remote application failure? about greenfield

[jpeeler]

Thanks for fixing up the minor issues I found. Turns out, I believe I confused myself while working remotely and forgot that I was running the compositor proxy inside a container. So that's why it couldn't find the expected binaries. Perhaps it should be mentioned in the docs that gstreamer plugins are required and note the useful tool gst-inspect-1.0 for verifying plugin installation.

All that said I got things working! Need to play around with it a bit more.

Does this happen for all applications or a specific one?

As for the documentation & ffmpeg issue, there was recently a big update so some things might have slipped through. Thanks for reporting these!

[jpeeler]

It was for both applications I tried - I assume I didn't mess the config up.

[Zubnix]

I was able to reproduce the errors, however they are not the cause of the failed application launch as qalculate-gtk works just fine here. The reason qalculate-gtk is not launching is because the compositor-proxy-cli can not find it "message": "spawn qalculate-gtk ENOENT".

[jpeeler]

I saw that. I don't know how it is unable to find it though?

❯ type qalculate-gtk
qalculate-gtk is /usr/bin/qalculate-gtk

Am I completely misunderstanding what the compositor-proxy-cli is capable of?

[Zubnix]

I don’t think you are doing anything wrong or misunderstanding anything. The name of the application is basically used in a fork call so theoretically if it’s on the PATH of the compositor-proxy-cli it should be found. You could try with the absolute path if for some reason the PATH environment variable is not working. I’m a bit confused why it’s not being picked up in your case 🤔

[jpeeler]

Yeah that's why I'm confused, I already tried both the full path and just the base name as in the examples. I can retry later in the week locally as I'm currently executing on a remote machine. But I have my doubts that the path is not being included in a standard linux binary directory.

I've fixed the build errors and added argument and environment logging when launching child applications. You will need to rebuild compositor-proxy. If all went well, you should see something like this:
