At this moment packages in core/extra are: nginx 1.12.1-1 pacman 5.0.2-1 nginx -V has --with-cc-opt='-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fno-plt -D_FORTIFY_SOURCE=2' but the pacman 5.0.2-1 version of /etc/makepkg.conf doesn't have the -fno-plt argument. I'd assume nginx 1.12.1-1 was compiled on a system with pacman 5.0.2-2 from testing? https://git.archlinux.org/svntogit/packages.git/diff/trunk/makepkg.conf?h=packages/pacman&id=0cd22d4454e0e1b3ae589b95274f808001465c15 Is this allowed? I suspect this is one of the reasons I can't compile a dynamic module for nginx -- damjan
