This document describes the installation of Slash'EM with an X11 interface. There are no explicit UNIX dependencies in this code, but we have only tested it under UNIX, using X11R4, X11R5, or X11R6. We have two reports that the code also works under DesqView/X on MS-DOS with djgpp, but you will have to add dependencies for the X code to that makefile before you can use it. Other X11R4+ platforms may work as well, with some tweaking likely. Follow WIN* in sys/unix/Makefile.src for compilation hints. (If you try to compile it with X11R3 or earlier, you will get many errors, starting with complaints about XtPointer not being declared. If you get around the compilation problems, you will still need a recent library of Athena Widgets to link against. Once compiled, you can probably run it under an R3 X server, though.) The reason this uses the Athena widget set is that the Athena widgets come free from MIT (like X11). Unfortunately, the companies that resell X11 (value subtracted er, added software; yea, yea, that's the ticket) usually discourage its use by either omitting the set or putting it on the "unsupported" portion of their tape. If you do not have the Athena widgets, you may obtain them via anonymous ftp from ftp.x.org. To use this code, define X11_GRAPHICS in include/config.h. (You can comment out TTY_GRAPHICS or change DEFAULT_WINDOW_SYS if you want to, but there's little reason to do so. The X11 version almost requires a config file for full effect, so you can just as well set windowtype there; also, you or someone else might just possibly be stuck in a situation where you can't use the X version -- over a non-blindingly-fast modem, say.) You may also want to define USE_XPM, GRAPHIC_TOMBSTONE as discussed below. In src/Makefile, add $(WINX11SRC), $(WINX11OBJ), and $(WINX11LIB) to WINSRC, WINOBJ, and WINLIB respectively, and compile. This will give you an executable supporting both X11 and tty windowing. If you want to use the optional tiles (multicolored pictures instead of a replacement font), you will need to have the win/share files and change the CF_SHARE_DATND setting in the top Makefile to contain the tile files before you do your 'make all'. Include x11tiles for the 16x16 tile set and x11bigtiles for the 32x32 set. The available tile sets should be defined in the configuration file. The tiles option can then be used to select the initial tile set or unset to use ASCII characters. See win/x11/slashem.rc and the Guidebook for more information. When using tiles, you have the option of defining USE_XPM in config.h. This causes Slash'EM to use the XPM file format for the "x11(big)tiles" file rather than a custom format. Since the XPM format can be processed by existing tools such as PBMPlus and XV, you can modify the tiles to suit your environment. For example, you may magnify them for display on high-resolution screens using the following command: xpmtoppm x11tiles | pnmscale -xscale 1 -yscale 1.6875 | pnmdepth 255 | ppmquant 100 | ppmtoxpm >x11tiles_big.xpm To use XPM, you must have the free XPM libraries installed in your system. Official xpm releases can be found by ftp on: ftp.x.org (126.96.36.199) contrib/libraries (Boston, USA) avahi.inria.fr (188.8.131.52) pub/xpm (Sophia Antipolis, France) If you do choose to define USE_XPM, be sure to add "-lXpm" to WINX11LIB in src/Makefile. If you define USE_XPM in config.h, you may also define GRAPHIC_TOMBSTONE which causes the closing tombstone to be displayed from the image file specified by the "tombstone" X resource (rip.xpm by default). In this case, make sure the top Makefile CF_SHARE_X11ND also contains rip.xpm. Whether or not you install tile support, you can provide support for special graphics symbols via alternate fonts. (The fonts and tiles cannot be used at the same time, but the same executable handles both.) The two included X11 fonts use the general Slash'EM map area remapping to represent object/dungeon/trap/effect characters (see win/X11/slashem.rc and the Guidebook) as monocolored symbols and monsters as monocolored letters. For instance, a ruby potion will show up as a potion symbol in red. It's easier to see the difference between fonts and tiles than to describe it. :-) Unless you are the only one using your executable and you already know which you prefer, we suggest installing the optional files for both possibilities and letting each person decide for themselves. To use the included fonts, you will need to install one or both of them and then use the symbol mappings found in slashem.rc. The fonts are found in nh10.bdf and ibm.bdf. You first need to convert the bdf files to whatever form your X11 server recognizes (usually using a command called bdftosnf for R4 servers or bdftopcf for R5 servers). Then run mkfontdir on the directory containing your font files (you might want to copy them to GAMEDIR, from the top Makefile, after you've done "make install"). If these commands aren't familiar, talk to your local X11 guru and read the man pages. Finally, add that directory to your font search path (e.g. xset fp+ GAMEDIR, setting GAMEDIR to the value of GAMEDIR in the top Makefile). Alternatively, you (assuming you are a system administrator) can install the fonts in your standard X11 font directory. If you do not install the fonts in the standard X11 font directory, all persons playing nethack must add that "xset fp+" command to their .xinitrc file, or whatever file they execute when starting X11. Adding the "xset" command to the nethack.sh is also an alternative, though it may clutter your X11 font search path after playing several games, so this method is not recommended. See the note below for the alternative installation procedure for Sun's OpenWindows. If you're using file areas, then the fonts can go in any sensible directory. FILE_AREA_SHARE is suggested for pcf fonts and FILE_AREA_UNSHARE for snf fonts. If your X11 include files and libraries are not installed in a standard place (i.e. /usr/include/X11 and /usr/lib respectively) you will need to prepend an appropriate -I
parameter to CFLAGS and a -L parameter to LFLAGS, setting to the place to find the include and library files for X11. Finally, you should also install the SlashEM.ad file as SlashEM in the normal X11 applications defaults directory. Alternatively, each person may append the contents of this file to their .Xdefaults file. A second alternative is copy SlashEM.ad to SlashEM in GAMEDIR (or FILE_AREA_SHARE) (from the top Makefile) and add a line to nethack.sh specifying this additional applications defaults directory: XAPPLRESDIR=$HACKDIR; export XAPPLRESDIR (Replace $HACKDIR with the value of FILE_AREA_SHARE if appropriate.) Three icon suggestions to the window manager are supported: nh72, nh56, and nh32. Data for them comes from the source files nh72icon, nh56icon, and nh32icon; they are compiled into the program via #includes in winX.c. Selection between them is controlled by the "icon" resource in SlashEM.ad; the default is nh72. Sorry, an Imakefile is not included. Unlike many X11 programs, X11 support is only a small, optional, part of nethack, and the Makefile is needed for systems that don't use X11. Notes for Sun's OpenWindows: 1. For OpenWindows 3.0 (NOT 2.x), define OPENWINBUG in include/unixconf.h. The library bug from SunOS 4.1.x is fixed in Solaris 2.x (or when proper Sun patches have been applied to 4.1.x), so it is also unnecessary there. (Defining it when unnecessary causes the same problem being avoided when it is necessary. :-) 2. In addition to the changes suggested by the comments in src/Makefile, -- for OpenWindows 2.x and 3.0 (NOT 3.1) (i.e., versions for SunOS 4.x), add -I/usr/openwin/include to CFLAGS, -L/usr/openwin/lib to LFLAGS, and -lm to WINX11LIB in src/Makefile. -- for OpenWindows 3.1 (i.e., versions for Solaris 2.x), add -I/usr/openwin/include to CFLAGS, -L/usr/openwin/lib -L/usr/ccs/lib -R/usr/openwin/lib to LFLAGS, and -lsocket -lnsl -lm to WINX11LIB in src/Makefile. (Naturally, if your OpenWindows is installed elsewhere, adapt the openwin paths.) This will allow you to create a game executable. 3. Run the fonts through convertfont and run bldfamily on the directory. Now you must let your X server know where to find the fonts. For a personal installation, the simplest thing is to include the directory of the fonts in the environment variable FONTPATH, as set in your .profile or .login before starting the server. For a multi-user installation, you have the various "xset fp+" options outlined above for standard X. 4. Something must still be done with the SlashEM.ad file -- all three of the possibilities mentioned for standard X11 should work. Notes for AIX 3.2: 1. AIX 3.2 includes the Athena Widget Toolkit library (and other things) under the /usr/lpp/X11/Xamples tree, so you will have to add -L/usr/lpp/X11/Xamples/lib to LFLAGS. If you can't find libXaw.a on your first build, go into /usr/lib/X11/Xamples, read the README file, and build the library. Notes for XFree86 - (on linux and BSD386 platforms) 1. Edit src/Makefile for linux/BSD386. Even though you use the Open Look Window manager, do not define OPENWINBUG. Use the standard X11 object and library options. 2. Follow the standard installation directions defined above.
