Avahi fails to emerge on my hardened x86 Gentoo Linux box. It complains about incosistant threading. Reproducible: Always Steps to Reproduce: 1. set up a hardened gentoo x86 bow w/ glibc 2.5-r4 2. emerge avahi Actual Results: avahi crashed Expected Results: avahi should emerge. the ebuild cranks out. ::snip:: checking for the pthreads library -lpthreads... no checking whether pthreads work without any flags... no checking whether pthreads work with -Kthread... no checking whether pthreads work with -kthread... no checking for the pthreads library -llthread... no checking whether pthreads work with -pthread... yes checking for joinable pthread attribute...

Guess I should have done that in reverse...
configure:20459: i686-pc-linux-gnu-gcc -o conftest -shared -fPIC -Wl,-z,defs -march=prescott -O2 -pipe -g -ggdb -fstack-protector -pthread -nopie conftest.c -lpthread >&5 i686-pc-linux-gnu-gcc: -shared and -static|pie|fPIE|fpie|fno-PIC|fno-pic|nopie are incompatible Your LDFLAGS="-nopie" is breaking it. I don't consider -nopie a supported global flag for LDFLAGS, as LDFLAGS is always used, not only for ET_EXEC. We could argue that -nopie is only for ET_EXEC and with -shared the linker should ignore it. Hardened Team, your opinion?
I'd forgotten about this bug. removing -nopie from ldflags appeared to have made it work. I should have posted this 14 months ago. I recall I got the idea from somewhere, but I don't recall where.
