[David I <dav.sec.lists@xxxxxxxxx>]

Hello,

I am unable to mcompile xen-tools from source.

here is the "stacktrace":

I was able to compile dist-xen correctly though. But dist-tools fails with this error, I have seen a similar request here:

https://stackoverflow.com/questions/63525163/usr-bin-ld-utils-o-data-rel-local0x0-multiple-definition-of-xprintf-xs

I have tried to compile xen from source also on this same configuration,

in stable-4.12, stable-4.13, stable-4.14, each time I was able to  compile xen but failed to compile xen-tools.

the debian package works fine and is in version 4.11.

So my question would be, is there a patch for this issue ? and how the debian team could compile originally the debian source package ? I suppose I am not the first user to encounter this.

Thank you for your answers ;-)

David
