[Xen-users] Xen Cross compilation Issues on Ubuntu

[kasandesh <kasandesh@xxxxxxxxxxxxxx>]

Hello All,

Greetings of the day and a very happy new year.

I am trying to cross compile the xen for arm64 target architecture and facing weird errors on ubuntu 18.04 machine.

While configuration, if arm64 compiler is found, then the configure halts at finding uuid.h

```

root@linux:/home/user/Projects/xen# ./configure --build=x86_64-unknown-linux-gnu --host=aarch64-linux-gnu

checking build system type... x86_64-unknown-linux-gnu

checking host system type... aarch64-unknown-linux-gnu

Will build the following subsystems:

   xen

   tools

   docs

configure: creating ./config.status

config.status: creating config/Toplevel.mk

config.status: creating config/Paths.mk

=== configuring in tools (/home/sandeshashok/Projects/motius/source_code/xen/tools)

configure: running /bin/bash ./configure --disable-option-checking '--prefix=/usr/local'  '--build=x86_64-unknown-linux-gnu' '--host=aarch64-linux-gnu' 'build_alias=x86_64-unknown-linux-gnu'                     'host_alias=aarch64-linux-gnu' --cache-file=/dev/null --srcdir=.

checking host system type... aarch64-unknown-linux-gnu

checking for aarch64-linux-gnu-gcc... aarch64-linux-gnu-gcc

checking for C compiler default output file name... a.out

configure: error: cannot find a valid uuid library

configure: error: ./configure failed for tools

```

However, if i don't path to the cross compiler, then the configuration works successfully.

```

```

Did anyone else observe this ?

If this has been fixed please direct me to the link.

I have been working on this for sometime and issue still exists. Tried the wiki page for cross compiling as mentioned in the link https://wiki.xenproject.org/wiki/Xen_ARM_with_Virtualization_Extensions/CrossCompiling, however it isn't successfull as well.

Best Regards,
