[yocto] Problem with packages during "devtool build"

[Raymond Yeung]

Hi Robert,


I'd already read the out-of-tree example; it's the first thing I checked.


After some changes in 3rd party Makefile, I'm running into errors in do_compile step.  My new question now is, how the Makefile picks up cross-compile INC path, as well as the LINKER path.


The variable KERNEL_SRC isn't enough to provide the needed clues for the above.  And it'd be a bad idea to hardcode paths in 3rd party code.


Is there an easy way to have devtool pass in more variables?  And what variables should we use?


Raymond

Did you have a look at this out of tree kernel module example?

https://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta-skeleton/recipes-kernel/hello-mod

You might want to use this makefile and add your stuff there.
