Cygwin-mingw compilation

Using the Configure Script to Compile Under Cygwin; and Musings Upon Regexps
I have submitted the enclosed patches to the tracker. This was written to document a way to build Slash'EM. It also is intended to point out a few problems with the current 8E0F1 sourcetree, and provide suggested patches where possible. We will use the Cygwin toolset to compile Slash'EM. We want to be able to use tile graphics and sounds, as well as the traditional text mode. We also want the resulting executables to be usable on any Windows install without needing Cygwin to be installed. I banged on the provided makefile for Cygwin enough to know that I wasn't going to be able to use it to compile. Besides, we want to be able to run the game anywhere. So we'll target the mingw subsystem of Cygwin. And we'll use the automake configurator. I was surprised how well it works. Note: the toolchain used is called mingw, but the Cygwin FAQ (6.10) claims that the actual MinGW project is a "completely separate effort." So I guess it's not really MinGW. These Cygwin packages are required or desired: base:coreutils base:bash base:grep base:gzip base:tar devel:binutils devel:bison (optional) devel:flex (optional) devel:gcc devel:gcc-mingw devel:gdb (optional) devel:make devel:mingw-runtime utils:cygutils utils:diffutils utils:patch (possibly more....) A hint on the Cygwin setup program: it's much easier to use if you maximize the window. Start a bash shell using one of the shortcuts, or start a rxvt window if you have that installed. Enter "gcc" to check that you can run the compiler. It should give the error "gcc: no input files". Move the archive to the place where you want to keep the game. If you want to use unix-isms, put it in /usr/local/src. If you want to use windows- isms, put it in C:\Program Files\SlashEM, which Cygwin knows by the name "/cygdrive/c/Program Files/SlashEM" (with the quotes). Note: Cygwin uses case-sensitive filename conventions by default, so get the case right. (Or turn it off by setting an environment variable "CYGWIN=glob:ignorecase".) Unpack the archive: tar xzvf se008e0f1.tar.gz Apply these patches: chdir into the slashem-0.0.8E0F1 subdirectory and issue this command: PATCH_VERSION_CONTROL=numbered patch -p1 -N -b < {location_of_this_file} That will apply all of the patches in this file, unless they have already been applied and are therefore not needed. The configure script needs a slight tweak: =============================================================================== diff -rU5 slashem-0.0.8E0F1-pristine/configure slashem-0.0.8E0F1/configure --- slashem-0.0.8E0F1-pristine/configure 2006-12-30 05:04:53.000000000 -0800 +++ slashem-0.0.8E0F1/configure 2007-07-28 08:15:47.926500000 -0700 @@ -4230,11 +4230,11 @@ CNF_SHARE_DATND= WINTTYLIB= if test "$enable_tty_graphics" != "no"; then if test $host_os = mingw32; then - EXTRA_UNSHARE=nhdefkey.dll nh340key.dll nhraykey.dll + EXTRA_UNSHARE='nhdefkey.dll nh340key.dll nhraykey.dll' CFLAGS="$CFLAGS -DWIN32CON" WINTTYLIB="" WINSRC="${WINSRC} \$(WINTTYSRC)" WINOBJ="${WINOBJ} \$(WINTTYOBJ)" =============================================================================== Note for automake/makefile maintainer: it would be strongly preferred to have one LFLAGS for the main game executable, one for the ancillary utilities, and a third for the DLLs.

I believe that is also true when compiling targetting Cygwin. The MSC makefile "solves" this by splitting the executable into two versions, text and graphics. At 'make install' time, there are some chmod commands that are hardcoded instead of using the $(CHMOD) variable.

The file 'Guidebook' doesn't get built properly as I am missing a tool named 'col'. It appears that col isn't provided by Cygwin; either that or I simply can't figure out what package has it. This is irrelevant under Windows since the file that is installed is 'Guidebook.txt'. A request: when compiling the level files, could we compile them all at once? Doing this: ../util/lev_comp ./beholder.des ./bigroom.des ./blkmar.des ./castle.des ./grund.des [...] is much faster than: ../util/lev_comp ./beholder.des ../util/lev_comp ./bigroom.des ../util/lev_comp ./blkmar.des ../util/lev_comp ./castle.des ../util/lev_comp ./grund.des [...] === Optional to get regular expression support: =============================== Getting support for regexps under Cygwin is not terribly hard. First you need to get the GNU rx 1.5 tarball. Build it for mingw. The trick is to set an env var CC='gcc -mno-cygwin' before running configure. Both the old regex 0.12 and the new rx 1.5 appear to work, as long as you compile targetting mingw. However, regex.o must be put into a library manually. ar rc libregex.a regex.o; ranlib libregex.a Put header files in \cygwin\usr\include\mingw; libs in \cygwin\lib\mingw. I initially had crashes using the rx library, but I cannot reproduce them anymore. I might not have targetted MinGW when I first compiled it. USER_SOUND_REGEX can only use the old regex library, not the newer rx library. Personally I prefer the rx library. I like the operator syntax better. And I don't care about sounds, and if I did, I'd be fine with the simple globber. Anyway. To use the old regex 0.12 library, you need to put: =============================================================================== #if 1 # define USE_REGEX_MATCH # define GNU_REGEX # define __need_size_t # include <stddef.h> //SWD regex.h needs size_t but doesn't pull it in. # include <regex.h> //SWD manually installed gnu regex 0.12 package. # define USER_SOUNDS_REGEX // SWD only works with GNU_REGEX. #endif =============================================================================== at the end of include/config.h section 5. In addition, comment out everything related to "REGEX" in include/autoconf.h. Finally, edit src/Makefile, adding "-lregex" to the "WINMSLIB=" line. make clean; make all Regex power users may wish to tweak the reg_syntax_t variable to suit their preferences. See regex.h and regex.info for documentation on this. Testing the regex library: add these lines to the defaults.nh file: =============================================================================== OPTIONS=menucolors MENUCOLOR=" 0%$"=white&bold MENUCOLOR=" \([1-9]\|1[0-9]\)%$"=lightcyan MENUCOLOR=" [234][0-9]%$"=yellow MENUCOLOR=" [567][0-9]%$"=orange MENUCOLOR=" \([89][0-9]\|100\)%$"=red SOUNDDIR=c:\windows\media SOUND=MESG "short sword" "start.wav" 100 SOUND=MESG "You \(throw\|shoot\)[^b-z]*\(dart\|arrow\|ya\|bolt\|dagger\|bullet\|grenade\|rock\)s*" "Windows XP Recycle.wav" 100 =============================================================================== That makes the spell menu (viewed by the plus key) highlight your chances of casting each spell you know. And there will be a tick every time you see or manipulate a short sword, and a rustling every time you throw or fire two or more missiles. Rogues are good for testing this. The firing regexp doesn't quite work as expected, since there is no message at all if you fire exactly one projectile. Alternately, to use the Posix-compliant rx library, put: =============================================================================== #if 1 # define USE_REGEX_MATCH # define POSIX_REGEX # define __need_size_t # include <stddef.h> //SWD rxposix.h needs size_t but doesn't pull it in. # include <rxposix.h> //SWD manually installed gnu rx 1.5 package. #endif =============================================================================== at the end of include/config.h section 5. In addition, comment out everything related to "REGEX" in include/autoconf.h. Finally, edit src/Makefile, adding "-lrx" to the "WINMSLIB=" line. make clean; make all Testing the rx library: add these lines to the defaults.nh file: =============================================================================== OPTIONS=menucolors MENUCOLOR=" 0%$"=white&bold MENUCOLOR=" ([1-9]|1[0-9])%$"=lightcyan MENUCOLOR=" [234][0-9]%$"=yellow MENUCOLOR=" [567][0-9]%$"=orange MENUCOLOR=" ([89][0-9]|100)%$"=red =============================================================================== That makes the spell menu (viewed by the plus key) highlight your chances of casting each spell you know.
