I have been working with BuildStream quite a bit lately, mostly on the next Freedesktop SDK.
BuildStream is still changing quickly, so upstream recommends installing from Git.
Eventually though, we will want to have packages of the latest release in all major Linux distributions. To that end, I've just packaged BuildStream for Fedora in a Copr:
$ sudo dnf copr enable bochecha/buildstream
$ sudo dnf install buildstream
You can also install the buildstream-docs
package, and then the documentation
will be visible in Devhelp or GNOME Builder.
For now I'll keep these packages in the Copr. I'll move them to the Fedora official repositories when I'm happy with them, though.
Let me know if they work for you… or if they don't!
