Thanks for your replies, I've managed to compile it using a chroot as suggested by Peter. I just grabbed a pre-built rootfs from here : https://wiki.debian.org/Arm64Port #Pre-built_Rootfses, then installed qemu-user-static with apt-get and run the build from the chroot.
Somehow "apt-get build-dep -a arm64 qemu" didn't work, I had tried to do "dpkg --add-architecture arm64 && apt-get update" before running this command but it couldn't find the needed packages, not sure why. In any case thanks for your help :) -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1658120 Title: building with gcc-aarch64-linux-gnu Status in QEMU: Invalid Bug description: Hi, while trying to build qemu v2.8.0 with gcc-aarch64-linux-gnu cross-compiler I'm getting the following : In file included from /usr/include/x86_64-linux-gnu/sys/syscall.h:31:0, from /root/qemu/util/compatfd.c:21: /root/qemu/util/compatfd.c: In function 'qemu_signalfd': /root/qemu/util/compatfd.c:103:19: error: '__NR_signalfd' undeclared (first use in this function) ret = syscall(SYS_signalfd, -1, mask, _NSIG / 8); ^ /root/qemu/util/compatfd.c:103:19: note: each undeclared identifier is reported only once for each function it appears in /root/qemu/rules.mak:59: recipe for target 'util/compatfd.o' failed make: *** [util/compatfd.o] Error 1 I had configured it with : ../configure --target-list=x86_64-linux-user --static --cpu=aarch64 And I'm on : Linux ubuntu-512mb-fra1-01 4.4.0-59-generic #80-Ubuntu SMP Fri Jan 6 17:47:47 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux Thanks To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1658120/+subscriptions
