Thanks Wookey and Richard.

I was able to resolve the pkg-config issue after installing it with - apt install pkg-config-aarch64-linux-gnu

I modified my configure command to below - ./configure --target-list=aarch64-softmmu --enable-kvm --enable-vhost-net --cross-prefix=aarch64-linux-gnu-

Now I am running into dependency issue on glib-2.4 and gthread-2.0.

rokhanna@rokhanna-dev ~/dev/qemu.git $ ./configure --target-list=aarch64-softmmu --enable-kvm --enable-vhost-net --cross-prefix=aarch64-linux-gnu-

ERROR: glib-2.40 gthread-2.0 is required to compile QEMU

I have installed libglib2.0-0 using apt-get but I cant find libglib2.4. Any ideas how I can install that. Thanks in advance.

Thanks

Rohit

Hi,

I am trying to cross-compile QEMU for aarch64 target using the below toolchain http://releases.linaro.org/components/toolchain/binaries/4.9-2016.02/aarch64...

../configure --target-list=aarch64-softmmu --enable-kvm --enable-vhost-net --cross-prefix=~/Downloads/gcc-linaro-4.9-2016.02-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-

ERROR: pkg-config binary '/home/rokhanna/Downloads/gcc-linaro-4.9-2016.02-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-pkg-config' not found

First, "--cross-prefix=aarch64-linux-gnu-".

It is a prefix, not a path. You should have "$HOME/Downloads/gcc-linaro-4.9-2016.02-x86_64_aarch64-linux-gnu/bin" in your path in order to use that compiler.

Second, pkg-config is not part of a toolchain, but part of an entire OS distribution. If your host is debian or ubuntu, they ship a version configured for aarch64 cross-compilation. Which is helpful because...

Third, you're going to need a *lot* of aarch64 libraries in order to build QEMU. This is where OS support for cross-toolchains is key.

Thanks Richard, that was very helpful. I was able to resolve the issue with this. Thanks again!

Thanks

I'm fairly certain that you have installed libglib for the host, x86_64, but not the cross-compiled libraries for aarch64. This is what I meant when I said:

Try the following as root:

dpkg --add-architecture arm64 apt-get update apt-get install build-essential apt-get install libcairo2-dev:arm64
