Mike,<br />The hardcoded vs paths are not a safe assumption.&nbsp; <br />I would rather see agreement of how the environment should be configured prior to calling edk2 build and if being capable of building host os specific binaries is the requirement then that should be clarified and the scripts can be updated.&nbsp; That way this type of stuff is contained within environment specific scripts rather than the edk2 build system.&nbsp;&nbsp;<br /><br />thanks<br />Sean
