The Win32 port of GTK+ is a work in progress, and not as stable or correct as the Unix/X11 version. For more information about the Win32 port, see http://www.gimp.org/win32/ . This (CVS HEAD) version of the Win32 backend does *not* necessarily even compile properly. There is a gtk-1-3-win32-production branch that was branched off from before the addition of the no-flicker and other recent functionality. That is what should be used by "production" code until the CVS HEAD version is useable. (But note, the Win32 backend has never been claimed to be "production quality", although it works surprisingly well for the GIMP.) Note that right now (January 2002), the gtk-1-3-win32-production branch has more functionality and somewhat cleaner code in gdk/win32. The code that handles pixmaps and images (DIB sections) and colormaps (palettes) has been substantially refactored and cleaned up. (For instance, 256-color mode now work.) Those improvements have not yet been done here. Building GTK+ on Win32 ====================== There are two ways to build GTK+ for win32: 1) Use the autoconf-generated configure script, and the resulting Makefiles (which use libtool and gcc to do the compilation). I use this myself, but it might be hell to setup correctly. Personally I run configure with: CC='gcc -mpentium -fnative-struct' CPPFLAGS='-I/target/include' CFLAGS=-O2 LDFLAGS='-L/target/lib' ./configure --disable-static --prefix=/target --with-gdktarget=win32 --with-wintab=/src/wtkit126 --with-ie55=/src/workshop/ie55_lib --host=i386-pc-mingw32 --enable-maintainer-mode 2) Use the Microsoft compiler, cl and Make, nmake. Say nmake -f makefile.msc in gdk and gtk. Alternative 1 also generates Microsoft import libraries (.lib), if you have lib.exe available. It should also work for cross-compilation from Unix. There are hand-written makefiles for mingw (look for makefile.mingw in various directories), but those haven't been kept up-to-date, and probably won't work without editing. Sorry. If you make them work again, by all means do submit patches. Note that I use mainly gcc myself, and thus the build setup for Microsoft's nmake and cl might be a bit rusty. Hans Breuer has been taking care of those makefiles. At times, we disagree a bit, and the msc makefiles might not produce compatible or identically named DLLs and import libraries as the autoconfiscated makefiles and libtool do. Using GTK+ on Win32 =================== To use GTK+ on Win32, you also need either one of the above mentioned compilers. Other compilers might work, but don't count on it. The same instructions on how to set up a correct version of gcc should also be followed if you want to build applications that use GTk+ with gcc. For prebuilt developer packages (DLLs, import libraries, headers), see the above website. Multi-threaded use of GTK+ on Win32 =================================== Multi-threaded GTK+ programs might work in special simple cases, but not in general. Sorry. If you have all GTK+ and GDK calls in the same thread, it might work. Otherwise, probably not at all. Possible ways to fix this are being investigated. Wintab ====== The tablet support uses the Wintab API. The Wintab development kit can be downloaded from http://www.pointing.com. Pass the --with-wintab flag to configure if you use that. If you use nmake and you don't care for Wintab, undefine HAVE_WINTAB in config.h.win32 and remove references to the wntab32x library from the makefile before building. Libintl ======= GTK wants to be built with the GNU "intl" library for internationalisation (i18n). Get the version ported to Win32 (not a very big deal) from the web site mentioned above. The "intl" library as gets built as a DLL called libintl-1.dll. If you don't want any i18n stuff, undefine ENABLE_NLS, HAVE_GETTEXT and HAVE_LIBINTL in the config.h.win32 file, and remove references to the intl library from the makefiles. Note that while the GNU gettext package is under the GPL, the "intl" part of it is under the LGPL (like GTK or GLib), as of gettext-0.10.40. ActiveIMM ========= If you want to build a GTK+ that supports ActiveIMM (the Input Method Manager for non-EastAsia locales that can be used on Win9x/NT4), you need the dimm.h header file. That is somewhat difficult to find, but http://msdn.microsoft.com/downloads/samples/internet/wizard/ seems to be a good place to look nowadays. If you use autoconfiscated build, pass the --with-ie55 flag to configure specifyin the location of the ie55_lib directory created by downloading the IE5.5 headers and libs from the above URL. --Tor Lillqvist <tml@iki.fi>
