Thanks for comments, I'll create new version tonight.

Sounds reasonable, I'll do it.

Not sure, I have to explore it.

Ok, let it be 3.18.1. I just find 3.19-rc1 on
http://drvbp1.linux-foundation.org/~mcgrof/rel-html/backports/ (Temporary backports
release page, linked from homepage), I considered it as stable enough.

I do probably something wrong: content of $(LINUX_MAKE_FLAGS) aren't added, so at least
CROSS_COMPILE is missing. But That's for $(kconfig-package). It might not be needed for
linux extension.

Ok.

I'd keep the error messages as indication for user.


Kind regards,
