OpenEmbedded Recipes
This is my log of trying to understand what each element of a .bb file is.
linux recipes
Definitions
SECTION - Top level package section. base, kernel, libs, x11, x11/utils. This appears to be similar to a bbclass. How is this used?
DESCRIPTION - Description of package to be built. I assume this shows up in the ipkg meta data.
LICENSE - GPL or other. How is this used?
DEPENDS - This package cannot be built/recipe not baked until the packages/recipes listed in DEPENDS have been built/baked.
PR - How is this used?
DEFAULT_PREFERENCE - How is this used?
COMPATIBLE_MACHINE - A machine as described in local.conf and with an appropriate config file in OE/conf/machine. How is this used?
SRC_URI - Some documentation available at berlios.de.
S - Source directory, I think.
FILES_kernel-image - The complete path of the final kernel-image in the destination filesystem.
OS - How is this used?
ARCH - How is this used?
KERNEL_IMAGETYPE - Filename of the image to be built. The exact name is dependent on the architecture. Could be one of the following.
- vmlinux
- image
- uImage
- bzImage
- zImage
- zImage.flash
KERNEL_OUTPUT - Where in the kernel build tree is the final image.
COMPATIBLE_HOST - How is this used?
Functions
do_configure() - Runs before X and after Y. In the case of building a kernel
