This seems to be related to qemu. To my understanding qemu does not fully support threads. I have been running into exactly the same problem on stable/10 and also tried both with and without native-xtools, to no avail. Linking to pthreads does work on stable/10 running on an actual ARM, without problems. -- Arjan On May 27, 2015, at 6:04 AM, Renato Botelho wrote: > I’m building some packages for arm.armv6 on stable/10 for a while using poudriere + native-tools. Last week I updated jails to recent stable/10 and started to see the same issue on 2 ports (net/openldap24-client and net/ntp). I noted there were a lot of ARM MFCs recently so probably we got a regression at some point. > > I also created a regular jail, without native-xtools, and result is the same: > > checking for GNU Pth pthread.h... no > checking for sched.h...
