# Create prerequisites for building Genode for OKL4
#
# Prior building Genode programs for OKL4, the kernel bindings needed are
# symlinked to the build directory.
#
#
# Execute the rules in this file only at the second build stage when we know
# about the complete build settings, e.g., the 'CROSS_DEV_PREFIX'.
#

#
# Make OKL4 kernel API headers available to the Genode build system
#
# We have to create a symbolic link of OKL's 'include/l4' directory into our
# local build directory. If we just added the original 'iguana/include'
# directory to the include-search locations, we would pollute the include
# search space with all Iguana include files, not just the OKL4 API includes.
