Does anyone have a .bb example file?

xeno-config does not exist in bitbake so I get:
native/task.h: No such file or directory

Thanks for the help.

I made some progress. I try to compile it manualy and found that the include
path for xenomai headers is:
~/gumstix/gumstix-oe/tmp/work/armv5te-angstrom-linux-gnueabi/xenomai-2.4.6-r0/image/usr/include/xenomai

But I get an error from linker:

linus@domain.hid$ gcc
-I/home/linus/gumstix/gumstix-oe/tmp/work/armv5te-angstrom-linux-gnueabi/xenomai-2.4.6-r0/image/usr/include/xenomai

I do not understand why you do not use xeno-config.

Because xeno-config is for my computer but I am cross compilling with
bitbake.

I am still trying to understand how bitbake works. When I figure it out I
will post the solution :)

xeno-config is made to be run with cross-compiling. Most Xenomai users
are cross-compiling, so it would have been stupid to make something that
works only when not cross-compiling.
