[BUG] Crash on start (with or without camera connected)

[olemartinorg]

Information

• Version: 3.0.3
• libgphoto2 version: 2.5.27-1

When I tried this out today, on my Arch machine, it crashes node instantly when trying to get the first camera - even if there is a camera connected or not.

Example

const CameraList = require("@tsed/gphoto2-driver").CameraList;
new CameraList().load();

Output

$ node -e "const CameraList = require('@tsed/gphoto2-driver').CameraList; new CameraList().load();"

@olemartinorg The plugin is only supported for nodejs v12. There is a know issue with v14 and higher version here: node-ffi-napi/ref-napi#47

If you downgrade your nodejs version to v12, it should works as expected.

I'm not an expert in C++ and nodejs so I'm not able to fix that. I can try to find another way to manipulate array pointer without using ref-array-napi, but... I'm not sure how I'll doing that. Any help is welcome :)

See you

Oh, thanks for the explanation! I'm also not familiar enough with C++ to figure that out. Do what you want with this issue, I found other ways around the problem.

[Romakita]

Oh ok? What is it?

[olemartinorg]

I just call gphoto2 on the command line instead. It works well enough, and I've made workarounds for the things that are less than stellar.
