Building Givaro on Gentoo I have CXXFLAGS=-O2 -pipe -march=native -O2 -pipe -fabi-version=6 -msse -msse2 -msse3 -mssse3 -msse4.1 -msse4.2 -mavx
Your Redhat has CXXFLAGS=-O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fexceptions -fstack-protector-strong -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection Could the abi-version=6 be the issue?
