Description Flags
The .spec file difference from Copr build 10275322 to 10275655 none

Description marc 2026-03-11 10:41:23 UTC 
Spec URL: https://github.com/Mumbri-systems/Clipper2/raw/fedora-2.0.1/pkg/rpm/clipper2.spec

Description: The Clipper2 library performs intersection, union, difference and XOR boolean operations on both simple and complex polygons. It also performs polygon offsetting, and Constrained Delaunay Triangulation. This is a major update of my original Clipper library that was written over 10 years ago. That library I'm now calling Clipper1, and while it still works very well, Clipper2 is just better.

The srpm file is not available anymore.

> The srpm file is not available anymore.

That's weird, a bunch of my srpm-builds directories are empty.  Not all of them, but clipper2 and delabella are empty, even when I make a new build.

Comment 12 leigh scott 2026-05-12 23:18:00 UTC 
You have a missing isa on

Requires: %{name} = %{version}-%{release}

should be

Requires: %{name}%{?_isa} = %{version}-%{release}

Github is acting up, so I can't make a permanent link for the srpm at the moment, here is a temporary link:

Please use the sources released by upstream:
https://github.com/AngusJohnson/Clipper2/releases

instead of:
https://github.com/Mumbri-systems/Clipper2/releases

If you need to make changes on the original sources do that in spec file using commands or patches.
