Cross-compiler are nowadays widely available. So build testing your changes

I wish it was that simple. Nevertheless, I will try to prepare an environment
to perform such builds.
Cross-compiling the hypervisor is really easy ;).
1) Download the cross-compiler tarball (here one [1]) and uncompress it. You
can also install the one provided by your distro.
2) Build Xen hypervisor. Here an example for arm64:
42sh> cd xen.git/xen
42sh> make XEN_TARGET_ARCH=arm64 CROSS_COMPILER=<triplet>-
In my case, I am using the Arm toolchain AArch64 GNU/Linux target
(aarch64-linux-gnu). So the <triplet> would be aarch64-linux-gnu.
This is assuming you have the compilers binary in your PATH. If not, you can
use give the full path:
CROSS_COMPILER=/opt/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu/bin/aarch64-linux-gnu-
Awesome! That really works (especially thanks for the [1] link… finally some
toolstack that works on my system).
One change was needed: s/CROSS_COMPILER/CROSS_COMPILE/g
Oh yes, sorry for that. I didn't copy/paste for once.
Thanks!
Having this in a wiki would really help. Or have I missed it?
This is explained on the Xen on Arm wiki page [2]. But I have to admit the page
is difficult to go through. I need to find some time to rework it.
Cheers,
