I think the challenge here is a mixture of inconsistencies and challenges with our documentation on how to compile and the fact that we never considered anyone would try to compile on such an old version of Fedora…

I’m sorry you had to spend so much time on it, to be honest.

Excellent, so the patches applied

Hmm, I need to look at these - those should be even in Qt 5.1

And that is once again a libgit version that’s too old :-(

I really think you’ll be MUCH happier if you update Fedora.

On the flip side, I’d really love to be able to give people rock solid instructions that just work.
So I will work on scripting all this in a way that makes this more robust.

Thanks for your patience
