I'm trying to finalize all the builds for OpenEXR/Imath 3.1 in my side tag
but having a tough time with krita getting a few errors[1] like this:

Thoughts?
Please provide task URL, not only build log URL:
https://koji.fedoraproject.org/koji/taskinfo?taskID=74326592
By the way:
https://gitlab.com/libeigen/eigen/-/commit/c29935b323ffb0b903f640111f0a0b0440e94a2e
eigen3 Eigen/src/Core/arch/AltiVec/MatrixProductMMA.h contains
--------------------------------------------
#pragma GCC target("cpu=power10")
--------------------------------------------
but Fedora rawhide ppc64le build flags contains "-mcpu=power8 -mtune=power8", so
there is "target specific option mismatch", I guess.
As the above eigen3 commit shows, I think you should be able to workaround
this by the following, for example (on krita.spec)
--------------------------------------------
%build
%ifarch ppc64 ppc64le
%global optflags_orig %optflags
%global optflags %optflags_orig -DEIGEN_ALTIVEC_DISABLE_MMA
%endif
%cmake_kf5
--------------------------------------------
(see Eigen/src/Core/arch/AltiVec/MatrixProduct.h around the line 22)
Scratch build succeeded with the above workaround at least on ppc64le (other archs are
now under build):
