Plain and simple... I thought one could compile a kernel extension
(foo.ko) without full kernel sources, as the various include files
describing kernel interfaces and data structures are installed in
various places under /usr/include .
This seems to work fine in many cases.
Turns out, however, that at least one thing (namely vnode_if.h) is not
there, and it needs to be reconstructed using sys/kern/vnode_if.{pl,src}
So i wonder:
+ is it a desirable goal that one can compile kernel extensions without
requiring a full kernel source tree ?
+ if so, shouldn't we make sure that, as part of the creation of
/usr/include, a copy of vnode_if.h is generated somewhere (maybe
in /usr/include/sys or wherever is more appropriate) ?
+ are there other header files (and maybe objects, e.g. there is also
a vnode_if.o) which have similar problems ?
cheers
