Open source lxi-tools v2.0 released

<< < (12/22) > >>

EsPiFF:
sorry for mixing up the words "device" and "host". Luckily, you still understood what I was asking, and pointed me to the correct terms "lxi client", what is the PC. And "lxi server", what is the instrument.  :)

I will follow the development here. Great that you are already working on the instrument side. My guess is, when liblxi also supports writing an instrument with it, there will be millions of installations.

Possible problem? Or my misunderstanding?

I installed lxi-tools 2.3 via snap, on debian testing, and I am getting the following error message when running lxi-gui:
Failed to realize renderer of type 'GskGLRenderer' for surface 'GdkX11Toplevel': libEGL not available
I thought a snap was supposed to include all needed libs - or am I missing something?

Yes, it is supposed to but there is stuff that even the host environment must provide for snaps to work successfully. Is your Debian very old? Right, you are running testing. Well, testing is not considered stable so maybe it has issues. Does the snap on the stable channel (v2.2) work?

I've updated the snap edge channel to include the missing libegl so it might work now.

Thanks. I did "snap refresh", and now I am getting  a slightly different message:

Failed to realize renderer of type 'GskGLRenderer' for surface 'GdkX11Popup': Failed to create EGL display


Using "snap refresh lxi-tools --stable" does not produce any such errors on launching; launching seems much slower.

But lxi-gui starts regardless of these errors right?

I'm getting similar errors when I start lxi-gui from the edge channel. It is errors thrown from GTK4 - they seem to vary depending on GTK4 version used so I think it is ok to ignore them.

The difference of the snaps are that on the edge channel I'm using a new snap base image (core22). It should be faster to launch.
