Christoph Hellwig started a thread a while ago about integrating kerntypes
builds into kbuild, but I'm not sure anything came of it.
Unfortunately I have to build some kerntypes files nonetheless. :)
I'm currently building the kerntypes file as a hostprog, and forcing it to be
built w/ kernel flags:
# Kerntypes file
# hostprogs-y, hostprogs-m, host-progs gyrations for older kbuild compat
hostprogs-$(subst m,y,$(CONFIG_FOO)) := $(KERNTYPES_NAME)
host-progs := $(hostprogs-y)
$(KERNTYPES_NAME)-objs := kerntypes.o
always := $(host-progs)
# We compile/link it with kernelspace flags, even though it's not a module...
HOSTCFLAGS_kerntypes.o := $(NOSTDINC_FLAGS) $(CPPFLAGS) $(CFLAGS) \
$(EXTRA_CFLAGS) -g3
# -r -nostdlib etc because kerntypes.c has no main()
HOSTLOADLIBES_$(KERNTYPES_NAME) += -r -nostdlib
but this seems pretty hacky to me, at best.
It seems like maybe declaring it as a lib-y might work too, but my impression
is that these libs are really only intended to be linked into the kernel image
itself.
Any other suggestions on a clean way to do this with the existing kbuild
infrastructure?
Thanks,
-Eric
