# This shell script builds a vm.def file for the current VM variant.
# The .def file exports vtbl symbols which allow the Serviceability
# Agent to run on Windows. See make/windows/projectfiles/*/vm.def
# for more information.
#
# The script expects to be executed in the directory containing all of
# the object files.

# Note that we currently do not have a way to set HotSpotMksHome in
# the batch build, but so far this has not seemed to be a problem. The
# reason this environment variable is necessary is that it seems that
# Windows truncates very long PATHs when executing shells like MKS's
# sh, and it has been found that sometimes `which sh` fails.
