Will Not Compile(gstreamer error)

[ghost]

Using the latest version of Rustup and a freshly installed Pop! OS I keep running into an error every single time I run cargo install hunter the error I get is

https://pastebin.com/t2W0Hd3s

I already double checked and all my gstreamer things were installed correctly. Not sure why I am getting this error. Oh and your preinstalls for Ubuntu/Debian give me this error

Interesting. I don't use Ubuntu or any other Debian derivate, and those build dependencies were provided by other contributors.

It seems like the package gsteramer-app is missing. Are you sure it's installed correctly, including the -dev package? You also need gst-plugins-bad for the pnm (video frame to image) encoder.

That gstreamer stuff is only used for video previews. You can disable them by running "cargo install --no-default-features hunter".

The version on crates.io is rather old, I'm currently refactoring the media-preview stuff into a sub-workspace to isolate it more from the core stuff. I will push that to crates.io in a few days. In the mean time, I recommend using the github master branch.

The install instructions definitely need some improvements.

I triple checked that and it installed. Let me know if you want help rewriting the install instructions I am willing to help.

Even when I did run cargo install --no-default-features hunter I got a bunch of errors

You need to compile with a recent nightly compiler, that should fix that one. If you have rustup:

rustup toolchain install nightly rustup default nightly

Then recompile.

I got it installed and it can only be run from within the directory it was created however I can fix that on my end. I am guessing you are in Arch? Want me to close this issue or leave it open for now?

[rabite0]

I'm on Gentoo.

To install into ~/.cargo/bin run: cargo install --no-default-features --path .

Leave it open as a reminder to improve install instructions.

I should add a check in build.rs and warn users when they're not using a nightly compiler.
