#-PRE
# Linux hints file with support for multiple window ports (interfaces)
#
# This hints file supports tty, curses, x11, and Qt in the same binary,
# but:
#
#  - For x11 support, you'll need to obtain and install x11 development libraries.
#    For example, on Ubuntu 20.04 (as of August 2020):
#        sudo apt-get install libx11-dev
#        sudo apt-get install libmotif-dev
#        sudo apt-get install libxaw7-dev
#	 sudo apt install xfonts-utils
#       (That last one is for bdftopcf and mkfontdir utils)
#
#  - For Qt support, you'll need to obtain and install Qt.
#    For example, on Ubuntu 20.04 (as of August 2020):
#        sudo apt-get install qtbase5-dev
#        sudo apt-get install qtmultimedia5-dev
#
#    Another odd note about Qt on Linux is that if you find you are getting
#    the following error trying to run NetHack after you build it:
#         "error while loading shared libraries: libQt5Core.so.5:
#          cannot open shared object file: No such file or directory"
#    you may have to fix that (one-time only) by the following command:
#     sudo strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
#
#  - For curses support, you may need to obtain and install the
#    ncurses development libraries if they aren't already installed
#    with your distribution. They seem to be there already with Ubuntu 20.04, but
#    for example, if you needed to install ncurses:
#        sudo apt-get install libncurses-dev
#
#  - tty support shouldn't require any prerequisite additional packages.
#
# Assuming you have the prerequisite packages mentioned above, you can
# specify, right on the make command line, which window ports (or interfaces)
# to include in your build. Doing it via the make command line means that won't
# have to edit the Makefile.
#
# make WANT_WIN_QT=1 WANT_WIN_X11=1 WANT_WIN_CURSES=1 WANT_WIN_TTY=1 install
#
# Add WANT_DEFAULT=Qt (or other interface) if you want nethack to use
# something other than tty as the default interface.
#
# 1. Which windowing interface(s) should be included in this binary?
# One or more of these can be manually uncommented and/or can be specified
# on the 'make' command line.  If none are enabled, tty will be used.
#WANT_WIN_TTY=1
#WANT_WIN_CURSES=1
#WANT_WIN_X11=1
#WANT_WIN_QT=1

# 1a. What is the default window system?
# Exactly one of these can be manually uncommented and/or can be specified
# on the 'make' command line.  If none is enabled, the first among
# WANT_WIN_{tty,curses,X11,Qt} that is enabled will become default.
#WANT_DEFAULT=tty
