I figured that this was because I did not point to the L4Re build
directory. Now I have changed that appropriately, and the build runs a
bit further. Now I am getting the following error:

# make O=build/           
Package libio-io was not found in the pkg-config search path.
Perhaps you should add the directory containing `libio-io.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libio-io', required by 'libio', not found
Getting required compilation flags failed.
L4OBJ: /root/l4re-core-2011042112/src/l4/testbuild
L4_REQUIRED_MODS: stdlibs log l4re_c-util libio shmc
/root/l4linux/l4linux/arch/l4/Makefile:306: *** Aborting..  Stop.
make: *** [sub-make] Error 2

Looking into my L4Re build directory, I thought the modules are all
there:

# ls
-l /root/l4re-core-2011042112/src/l4/testbuild/pkg/cxx_libc_io/lib/src/OBJ-arm_armv7a-l4f/

Any idea what the problem here is?

Thanks,
Anna
