--- Comment #11 from cqwrteur <unlvsur at live dot com> --- (In reply to Andrew Pinski from comment #6) > There is NO fix inside gcc/libstdc++. > THe only fix is your build of GCC (which includes the target libraries) > needs to be build against the oldest version of glibc you support. This is > something which GCC cannot control. > THIS IS HOW linking and backwards compatibility works. Try to create a gcc cross compiler 15 for glibc 2.25 for me. You cannot even do that. So what's the excuse?
