# Note: this script requires MacOS X 10.2 or greater, and builds diskimages
# which require MacOS X 10.1 or greater to install.
#
# Run from the unpacked survex-1.0.X directory like so:
#
#   ./buildmacosx.sh --install-wx
#
# This will automatically download and temporarily install wxWidgets
# (this script is smart enough not to download or build it if it already
# has).
#
# If you already have wxWidgets installed permanently, use:
#
#   ./buildmacosx.sh
#
# If wxWidgets is installed somewhere such that wx-config isn't on your
# PATH you need to indicate where wx-config is by running this script
# something like this:
#
#   env WXCONFIG=/path/to/wx-config ./buildmacosx.sh
