Re: [Xen-devel] Re: Problems with running xentrace

[Mark Williamson <mark.williamson@xxxxxxxxxxxx>]

Try doing a make clean before your make trace=y install.  The makefile doesn't 
allow make to identify what files need rebuilding when you add trace, debug, 
etc. to the rebuild, so you really do need to rebuild from scratch.

Cheers,
Mark
