Peek: Problem install peek on CentOS 7

Installations instructions are at https://github.com/phw/peek#installation

What problems do you actually have? As there are no CentOS packages I am aware of you can either install from source or try the Fedora packages and see if they are installable (probably not). Another option would be Flatpak, but not sure how this is supported in CentOS.

Another option is of course using the AppImage, that's maybe the easiest way if it is working on CentOS 7.

From source not work correctly.

Example, keybinder was installed - https://i.imgur.com/glYcHyj.png

This sounds like you are missing the corresponding development packages. I don't know about the package naming in CentOS, but you likely need to install the development packages for gtk3, cairo and keybinder3. The package names likely end with -devel, something like gtk3-devel, keybinder3--devel etc.

Hm...really does work :)

phw, thanks for helping!

I also succeeded local install. And I needed to install ffmpeg for animated gif after local install as described at Fedora in Readme.
