help building my own recipes

Hi,

I have a Beagleboard-C4, and have successfully built some default images.

I started to collect receipes for my own build, following their dependencies. At a point, i got the following error message:

ERROR: Failure expanding variable FILESPATH, expression was ${@base_set_filespath([ "/home/kgy/work/Yoctoproject/Poky/meta-kgy/yocto/recipes-ti/codec-engine/ti-codecs-omap3530-4_00_00_00-${MACHINE_KERNEL_PR}a", "/home/kgy/work/Yoctoproject/Poky/meta-kgy/yocto/recipes-ti/codec-engine/ti-codecs-omap3530-4_00_00_00", "/home/kgy/work/Yoctoproject/Poky/meta-kgy/yocto/recipes-ti/codec-engine/ti-codecs-omap3530", "/home/kgy/work/Yoctoproject/Poky/meta-kgy/yocto/recipes-ti/codec-engine/ti-codecs-omap3530-4_00_00_00", "/home/kgy/work/Yoctoproject/Poky/meta-kgy/yocto/recipes-ti/codec-engine/ti-codecs-omap3530", "/home/kgy/work/Yoctoproject/Poky/meta-kgy/yocto/recipes-ti/codec-engine/files", "/home/kgy/work/Yoctoproject/Poky/meta-kgy/yocto/recipes-ti/codec-engine" ], d)} which triggered exception SyntaxError: EOL while scanning string literal (FILESPATH, line 1)
ERROR: Command execution failed: Exited with 1
Summary: There were 2 ERROR messages shown, returning a non-zero exit code.

According to the answers i found in mail archives, a variable setting is missing, but i cannot determine which. It happened when 'meta-ti' was added.
How can i determine what is missing?

Thanx

Is the variable definition for MACHINE_KERNEL_PR valid?

Do a "bitbake <recipe> -e" to see the setting.
