Sam,
This piece of the top-level Makefile in current git causes an
out-of-tree driver Makefile to fail.
101 ifdef O
102 ifeq ("$(origin O)", "command line")
103 KBUILD_OUTPUT := $(O)
104 endif
105 endif
The out-of-tree driver Makefile contains an O=... directive that
(correctly) does _not_ specify the kernel source dir, and apparently
isn't overridden by the command line either. If in the above Makefile
snippet I change "command line" to "file", my out-of-tree make
succeeds. What do you think about allowing O= to come from a file in
addition to the command line?
Here are my attempts:
[EMAIL PROTECTED] atl1-2.0.7-20071202]$ make
make -C /lib/modules/2.6.24-rc3/source O=/lib/modules/2.6.24-rc3/build

Thanks for your help.
