Subject: [Buildroot] aarch64 : g++ is not working
Date: Tue, 11 Apr 2017 09:50:52 +1000	[thread overview]
Message-ID: <f53a3152-a0ad-d86d-a9d1-26da5dceb526@flatmax.org> (raw)

Hi there,

I have found that g++ is not working with aarch64. Not sure why it isn't 
working. If others can verify this problem, it is a pretty big show stopper.

I have checked the problem with rtorrent like so :

BR2_aarch64=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_PACKAGE_RTORRENT=y

When I execute rtorrent :

# rtorrent

/usr/bin/rtorrent: symbol '_ZSt15__once_callable': can't handle reloc 
type 0x407


Any one got any ideas on how to get g++ working with aarch64 and buildroot ?


I have tried to test on qemu like so :

make qemu_aarch64_virt_defconfig
make menuconfig # enable cxx and rtorrent

However, when I try to run qemu (looking at the file 
board/qemu/aarch64-virt/readme.txt) the kernel doesn't output during 
boot  - any suggestions on how to make this work ? I use the following 
command :

qemu-system-aarch64 -M virt -cpu cortex-a57 -nographic -smp 1 -kernel 
output/images/Image -append "console=ttyAMA0" -netdev user,id=eth0 
-device virtio-net-device,netdev=eth0


thanks

Matt
