# 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.

# Put temporary c-code and executable to calculate offsets here.
# Also put verification offset file here as well.
GENSRC_X11WRAPPERS_TMP := $(JDK_OUTPUTDIR)/gensrc_x11wrappers
# Put the generated Java classes used to interface X11 from awt here.

# The pre-calculated offset file are stored here:
