Actually, I wonder if this is the right thing to do... This is a
userspace library that requires a platform-specific linux/xxx.h. For an
external toolchain, these headers don't exist in
$(STAGING_DIR)/usr/include/linux
Directly using $(LINUX_DIR)/include means that the headers are not
patched for userspace. For those platform-specific headers that's
probably not a problem, but it's not good for e.g. linux/types.h.
An easy workaround is to use -idirafter instead of -I. However,
perhaps it's an even better idea to do 'make headers_install' as part of
the normal linux build process, so that packages depending on those
headers can use the patched version. But then again, is it a good idea to
replace the toolchain's kernel headers with a new set of kernel headers?
Any advice is welcome!
Regards,
Arnout
