Hello,
The ARB package FTBFS on ppc64el with GCC 14+ due to errors in the
Altivec code from the bundled Eigen (eigen-2.0.16).
The errors occur in
HEADERLIBS/eigen/Eigen/src/Core/arch/AltiVec/PacketMath.h. These
intrinsics are deprecated on little-endian PowerPC and now rejected by
modern GCC.
Upstream Eigen replaced these deprecated intrinsics with endian-agnostic
equivalents starting around version 3.3.9
Below is the commit of that change.
https://gitlab.com/libeigen/eigen/-/commit/1615a2799384a2964d01ba77fe98e3f6fcc412f4
ARB currently bundles an older Eigen (eigen-2.0.16) which predates those
fixes.
Thanks,
Trupti.
