Try the followings, to set up QEMU for AArch64...

# On ubuntu 13.10, start from here

git clone git://git.qemu.org/qemu.git

cd qemu

git submodule update --init pixman

git submodule update --init dtc



# install some tools

sudo apt-get install libglib2.0-dev

sudo apt-get install autoconf

sudo apt-get install libtool



# build & install qemu

mkdir build

../qemu/configure --target-list=aarch64-softmmu,aarch64-linux-user

make

sudo make install



# Drop attached file to binfmts folder

sudo apt-get install binfmt-support

sudo cp qemu-aarch64 /usr/share/binfmts

sudo update-binfmts --import qemu-aarch64

# If you don't have linaro tool chain,

# please download
http://releases.linaro.org/latest/components/toolchain/binaries/gcc-linaro-aarch64-linux-gnu-4.8-2014.03_linux.tar.xz


# after unzip, please do the following copy

cp ~/gcc-linaro-aarch64/aarch64-linux-gnu/lib/*
~/gcc-linaro-aarch64/aarch64-linux-gnu/libc/lib/aarch64-linux-gnu/


#
Then y
You need to set up correct sysroot path here, e.g.

# SYSROOT_PATH=/home/
your_home_folder
/gcc-linaro-aarch64/aarch64-linux-gnu/libc

export QEMU_LD_PREFIX=$SYSROOT_PATH



# Get here, Done!



Try to run the followings to verify qemu works...



$ cat tt
t

.c

#include <stdio.h>

int main(){printf("OK\n");}

$ aarch64-linux-gnu-gcc ttt.c

$ ./a.out

OK

Thanks,
-Jiangning
