Hmm, you are building against the default kernel link, right? What happens when you provide the target of the /lib/modules/2.4.33-ipipe-1.2-08/build link instead? Maybe those double links (/lib/modules/*/build and the xenomai links) somehow don't get resolved properly to the real path by RTnet's build system. Hell, we need to get rid of this autotools indirection cruft. Jan
