bitbake ignores DEFAULT_PREFERENCE

bitbake ignores DEFAULT_PREFERENCE

[Dmitry Vinokurov]

Hello,

I want to port OE to LPC3250 board and now I'm trying to build 
helloworld-image.

I've created lpc3250.conf in conf/machine:
TARGET_ARCH = "arm"
PACKAGE_EXTRA_ARCHS = "armv5te"
TARGET_CC_ARCH = "-fsigned-char -mfpu=vfp -mfloat-abi=softfp"

Then I've added DEFAULT_PREFERENCE_lpc3250 = "1" to 
'recipes/linux/linux_2.6.27.bb', but 'bitbake -v helloworld-image' 
downloads 2.6.23 kernel all the same. Re-reading all recipes database 
make no sense.

Could anybody advise, how this can be solved? I need to use exactly 
2.6.27 kernel as I know that it definitely works.

Thanks in advance.

Are you sure it downloads 2.6.23 to build your kernel and not the 
linux-libc-headers? Check the dependencies and what it's going to build by 
executing "bitbake <target> -g" and then poking into depends.dot...

Otherwise you can try setting PREFERRED_VERSION_virtual/kernel = "2.6.23" to 
override DEFAULT_PREFERENCE...

It could be downloading it for linux-libc-headers package too. bitbake -g
can help you here.

Yes, you're right, it was for linux-libc-headers package. I'm not so 
easily work with OE yet.
