hello, To spin up a nspawn container with a vanilla samba as an ad-dc controller I had a go on compiling samba latest stable. Building a vanilla samba 4.4.3 for aarch64 does not succeed due to an internal compiler error. I know I ‘am swimming on my own here, still severe enough to share it on this list. Especially as it builds just fine on X86_64 and armv7hfp – and- succeeded to build it against Centos 7 with ggc 5.1.1 form fedora repository’s. Building on an Odriod C2 running on a “debian” 3.14.67 kernel (part of) Build log using standard gcc 4.8.5: ../source3/smbd/notify.c: In function 'change_notify_create': ../source3/smbd/notify.c:297:1: internal compiler error: in fixup_reorder_chain, at cfgrtl.c:3336 Simplest way to reproduce is building samba 4.3.0-0.1.rc4 from fedora sources: http://ftp.nluug.nl/ftp/pub/os/Linux/distr/fedora/linux/releases/23/Everything/source/SRPMS/s/samba-4.3.0-0.1.rc4.fc23.src.rpm
