# This file is responsible for extracting the x11 native struct offsets to
# the xawt Java library. The tool needs to be run on the os/arch that
# will host the final jvm, thus the tool cannot be used when cross compiling.

# To enable cross compiling, the two versions of the generated offset file,
# sizes.32 and sizes.64 are committed into the source code repository.
# These are the ones used.

# However when not cross compiling, the offset generator tool is built and
# run, to verify that it still generates the same sizes.32 and sizes.64.
