SubjectRe: compiling external kernel modules (comedi.org)
Ok. Thanks. Now the bug is that comedi cannot find the file "Rules.make" 
which is apparently no longer there in 2.6. Is it right that the rules
are now integrated in the corresponding makefiles?

Can you recommend me a Makefile which I can take as a template? Comedi
uses some sort of autoconfig and I have to append then the "rules" to
the automatically generated makefile.

Another thing: can a prevent the kernel of generating the "Stage 2"? It
would be nice if the kernel doen't need to write to it's own directories
if it compiles external modules. The best thing would be that one could
compile external modules as a normal user and then only at the end
becomes root. In my case this would be convenient as my home is a NFS
directory which does not allow compiling as root. However the kernel
modules at the end are stored on a root writable directory.

removed the Rules.make includes from the comedi Makefiles:

2.4.21: only to test. Comedi cannot compile since an evil programmer has
removed Rules.make.

2.6.21: Comedi compiles without error since the kernel expects the
Makefile to trigger the make of modules which is no longer there.
