Bug 2319589

SFCGAL has an upstream patch in a merge-request:

  https://gitlab.com/sfcgal/SFCGAL/-/merge_requests/325

That merge-request was merged before the new release SFCGAL 2.0.0:

  https://gitlab.com/sfcgal/SFCGAL/-/releases/v2.0.0

There have been other changes upstream before that patch, so it doesn't apply cleanly to the f42 source. For example, if you apply this 

--- src/algorithm/straightSkeleton.cpp
+++ src/algorithm/straightSkeleton.cpp

     if (skeleton == nullptr) {

you end up with this

  extractPolygons(g, polys);

  for (auto &poly : polys) {
    Kernel::Vector_2                      trans;
    Polygon_with_holes_2 const            polygon = preparePolygon(poly, trans);
    SHARED_PTR<Straight_skeleton_2> const skeleton = straightSkeleton(polygon);

    if (!skeleton.get()) {
      BOOST_THROW_EXCEPTION(

where the penultimate line is not what it should be.

Results of building upstream release 1.5.2 in mock:

- epel10 with CGAL-6.0.1 fails at the same point and with the same error as the koji 1.5.0-1 build.
- epel10 with CGAL-5.6.2 fails at algorithm/union.cpp.o with "Error: unknown pseudo-op '.lbb7'".
- epel9  with CGAL-5.6.2 succeeds.
- epel9  with CGAL-6.0.1 fails at the same point and with the same error as the koji 1.5.0-1 build.

Results of building  upstream release 2.0.0 in mock:

- epel10 with CGAL-6.0.1 succeeds building 100% but then fails in doc.
- epel10 with CGAL-5.6.2 idem

"if it still fails to build", but now it does build. According to https://fedora.pkgs.org/rawhide/fedora-x86_64/SFCGAL-1.5.0-1.fc42.x86_64.rpm.html , only postgis depends on SFCGAL. And I have built postgis-f42 with SFCGAL-2.0.0, in its turn built against CGAL-6.0.1, so to me it seems that SFCGAL-2.0.0 can now move on to QA and into f42.

I have updated the spec file according to the patch proposed by you in 2319589#c4.

It is built now in Rawhide (F43): https://bodhi.fedoraproject.org/updates/FEDORA-2025-c6022e6999

I still have to backport it to F42. And maybe in EPEL. On in EPEL10?

For F42, the build+update is done: https://bodhi.fedoraproject.org/updates/FEDORA-2025-6a03036a2e

For EPEL10, I messed-up, and I need help from releng: https://pagure.io/releng/issue/12572 ... Sorry.

FEDORA-EPEL-2025-eb821d56bd (SFCGAL-2.0.0-1.el10_0) has been submitted as an update to Fedora EPEL 10.0.
https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2025-eb821d56bd

SFCGAL v2.0.0, compiled with CGAL 6.0.1, is now is f43 (rawhide), f42, and epel10. Closing this issue.

FEDORA-EPEL-2025-eb821d56bd has been pushed to the Fedora EPEL 10.0 testing repository.
