Segfault when trying to run the example on Linux

I cloned the repository and ran clojure -M -m com.phronemophobic.membrane-skija-example which resulted in the following:

Hi @wodin , I can try to look into this later this week. I suspect the issue can probably be fixed just by updating dependencies (also, the skija library has since moved to a new repository).

If you're interested, you can also try the skija example in the main membrane library which will probably be more update to date:

git clone https://github.com/phronmophobic/membrane.git
cd membrane
clojure -X:deps prep
clojure -M:skija -m membrane.skija

The skia and java2d backend are much better supported than the skija backend. Do you have a particular reason for preferring the skija backend? Mostly just curious.

[wodin]

Not really :) I assumed that the way to use skia was via skija.

I'll try the other backends
