Description Václav Kadlčík 2023-01-09 14:44:51 UTC 
Description of problem:

digikam is still failing with 11.3.1-4:

/usr/include/eigen3/Eigen/src/Core/util/BlasUtil.h:227:46: error: inlining failed in call to 'always_inline' 'Eigen::internal::blas_data_mapper<double, long, 0, 0, 1>::storePacketBlock<double __vector(2), 4>(long, long, Eigen::internal::PacketBlock<double __vector(2), 4> const&) constvoid': target specific option mismatch

See https://koji.fedoraproject.org/koji/taskinfo?taskID=95750885

Found and pointed out by Orion Poplawski in bz2140266#c8.


Version-Release number of selected component (if applicable):

gcc-11.3.1-4.el9


Additional info:

bz2140266 but its fix seems not to help with digikam

should have been "bz2140266 seems related but ..."
Comment 2 Václav Kadlčík 2023-01-10 08:32:04 UTC 
Reproduced without Koji and without mock on a RHEL 9.2 build
with gcc-11.3.1-4.3.el9.ppc64le:

1. Install/enable the CodeReady (CRB) and EPEL repositories

2. Install packages according to attached rpms.txt

3. Prepare the sources:

     mkdir -p rpmbuild/SPECS rpmbuild/SOURCES
     wget -O rpmbuild/SPECS/digikam.spec \
       https://src.fedoraproject.org/rpms/digikam/raw/59a551c6c1b4a104452a8ab4124cca5c6444cd57/f/digikam.spec
     wget -O rpmbuild/SOURCES/digiKam-7.9.0.tar.xz \
       https://ftp.fi.muni.cz/pub/kde/stable/digikam/7.9.0/digiKam-7.9.0.tar.xz

4. Add dependencies if missing:

     dnf builddep -y rpmbuild/SPECS/digikam.spec 

5. Build and check:

     rpmbuild -ba rpmbuild/SPECS/digikam.spec |& tee build.log
     echo $?
     grep error: build.log

Comment 5 Marek Polacek 2023-01-12 17:50:15 UTC 
OK, so this error persists:

/usr/include/eigen3/Eigen/src/Core/arch/AltiVec/MatrixProductMMA.h: In function 'Eigen::internal::storeAccumulator<Eigen::internal::blas_data_mapper<double, long, 0, 0, 1>, long, double __vector(2), 2l>(long, long, Eigen::internal::blas_data_mapper<double, long, 0, 0, 1> const&, double __vector(2) const&, __vector_quad*)void':
/usr/include/eigen3/Eigen/src/Core/util/BlasUtil.h:227:46: error: inlining failed in call to 'always_inline' 'Eigen::internal::blas_data_mapper<double, long, 0, 0, 1>::storePacketBlock<double __vector(2), 4>(long, long, Eigen::internal::PacketBlock<double __vector(2), 4> const&) constvoid': target specific option mismatch

and I think that's because part of the fix was only applied to GCC 12:
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102059#c34>:
"I don't think the r12-6219 commit qualifies for backporting."

This comment <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102059#c35>
mentions a few workarounds.  Maybe disabling LTO on ppc64le would help as well.

So I don't think I can backport a fix for this one, sorry.
