[PATCH 1/2] kernel.bbclass: pass KERNEL_VERSION through legitimize_package_name

[PATCH 1/2] kernel.bbclass: pass KERNEL_VERSION through legitimize_package_name

[Andreas Oberritter]

- KERNEL_VERSION may contain characters unsuitable for package
  names, e.g. underscores. Use legitimize_package_name to replace
  those characters.

[PATCH 2/2] kernel.bbclass: pass AR, NM and OBJCOPY to make

[Andreas Oberritter]

- Fixes build with certain vendor-supplied Montavista kernels.
- Pass the same set of variables to every invocation of make.
- Create KERNEL_*SUFFIX, TARGET_*_KERNEL_ARCH and HOST_*_KERNEL_ARCH
  for the three variables, analogue to LD.

Re: [PATCH 2/2] kernel.bbclass: pass AR, NM and OBJCOPY to make

[Phil Blundell]

I'm mildly curious as to what Montavista can have done that requires a
custom version of ar.  But the patch looks fine to me anyway.

I don't know whether this change came from Montavista or from the vendor
supplying the kernel sources. Anyway, someone changed CROSS_COMPILE to
override the environment, thus using a prefix different from the
toolchain built by OE.

CROSS_COMPILE   = $(shell if [ -f .mvl_cross_compile ]; then \
                                  cat .mvl_cross_compile; \
                          fi)

With the patch applied, the variable CROSS_COMPILE isn't used anymore,
because all cross-tools are specified on the command line in the same
manner.

Another way to solve this problem could have been to set CROSS_COMPILE
on the command line instead of in the environment. I haven't tried that.
I could create an updated patch if this was preferred.

Regards,
Andreas

Re: [PATCH 1/2] kernel.bbclass: pass KERNEL_VERSION through legitimize_package_name

[Phil Blundell]

I can't help thinking that, in this day and age, those PKG assignments
probably belong in some distro configuration rather than the recipe
itself, and it might be worth thinking about booting them out at some
point.  But, as long as they are there, your change is obviously
sensible.
