# Script to build a wxWidgets GTK version for BOINC

# Usage:
#  cd [path]/wxWidgets-3.0.2/
#  source path_to_this_script [--clean] [--debug] [--prefix PATH]
#
# the --clean argument will force a full rebuild.
# the --debug argument will build the debug version of the library
# if --prefix is given as absolute path the library is installed into there

# Patch wxwidgets to work with GCC6
# from https://github.com/wxWidgets/wxWidgets/commit/73e9e18ea09ffffcaac50237def0d9728a213c02
