The Win32 backend in GTK+ is not as stable or correct as the X11 one.

For prebuilt runtime and developer packages see

Building GTK+ on Win32
======================

First you obviously need developer packages for the compile-time
dependencies: Pango, atk, glib, gettext-runtime, libiconv, libpng,
zlib, libtiff at least. See
http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies .

After installing the dependencies, there are two ways to build GTK+
for win32.

1) GNU tools, ./configure && make install
-----------------------------------------

This requires you have mingw and MSYS.

Use the configure script, and the resulting Makefiles (which use
libtool and gcc to do the compilation). I use this myself, but it can
be hard to setup correctly.

The full script I run to build GTK+ 2.10 unpacked from a source
distribution is as below. This is from bulding GTK+ 2.10.9

MOD=gtk+
VER=2.10.9
THIS=$MOD-$VER
HEX=`echo $THIS | md5sum | cut -d' ' -f1`

for D in $DEPS; do
    PATH=/devel/dist/$D/bin:$PATH
    MY_PKG_CONFIG_PATH=/devel/dist/$D/lib/pkgconfig:$MY_PKG_CONFIG_PATH
done

libtoolcacheize &&
unset MY_PKG_CONFIG_PATH &&

(cd $TARGET/bin; strip --strip-unneeded *.dll *.exe) &&
(cd $TARGET/lib/gtk-2.0/2.10.0/loaders; strip --strip-unneeded *.dll) &&
(cd $TARGET/lib/gtk-2.0/2.10.0/immodules; strip --strip-unneeded *.dll) &&
(cd $TARGET/lib/gtk-2.0/2.10.0/engines; strip --strip-unneeded *.dll) &&
PATH=$TARGET/bin:$PATH gdk-pixbuf-query-loaders >$TARGET/etc/gtk-2.0/gdk-pixbuf.loaders &&
grep -v -E 'Automatically generated|Created by|LoaderDir =' <$TARGET/etc/gtk-2.0/gdk-pixbuf.loaders >$TARGET/etc/gtk-2.0/gdk-pixbuf.loaders.temp &&
mv $TARGET/etc/gtk-2.0/gdk-pixbuf.loaders.temp $TARGET/etc/gtk-2.0/gdk-pixbuf.loaders &&
grep -v -E 'Automatically generated|Created by|ModulesPath =' <$TARGET/etc/gtk-2.0/gtk.immodules >$TARGET/etc/gtk-2.0/gtk.immodules.temp &&
mv $TARGET/etc/gtk-2.0/gtk.immodules.temp $TARGET/etc/gtk-2.0/gtk.immodules &&
./gtk-zip.sh &&
(cd /devel/src/tml && zip /tmp/$MOD-dev-$VER.zip make/$THIS.make) &&
manifestify /tmp/$MOD*-$VER.zip

You should not just copy the above blindly. There are some things in
the script that are very specific to *my* build setup on *my* current
machine. For instance the "latest.sh" script, the "usedev" and
"usemsvs6" shell functions, the /devel/dist folder. The above script
is really just meant for reference, to give an idea. You really need
to understand what things like PKG_CONFIG_PATH are and set them up
properly after installing the dependencies before building GTK+.

As you see above, after running configure, one can just say "make
install", like on Unix. A post-build fix is needed, running
gdk-pixbuf-query-loaders once more to get a correct gdk-pixbuf.loaders
file.

2) Microsoft's tools
--------------------

Use the Microsoft compiler, cl and Make, nmake. Say nmake -f
makefile.msc in gdk and gtk. Be prepared to manually edit various
makefile.msc files, and the makefile snippets in build/win32.

Alternative 1 also generates Microsoft import libraries (.lib), if you
have lib.exe available. It might also work for cross-compilation from
Unix.

I use method 1 myself. Hans Breuer has been taking care of the MSVC
makefiles. At times, we disagree a bit about various issues, and for
instance the makefile.msc files might not produce identically named
DLLs and import libraries as the "autoconfiscated" makefiles and
libtool do. If this bothers you, you will have to fix the makefiles.

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. Look for
prebuilt developer packages (DLLs, import libraries, headers) on the
above website.

Multi-threaded use of GTK+ on Win32
===================================

Multi-threaded GTK+ programs might work on Windows 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.

Active IMM
==========

If you want to build a GTK+ that supports Active IMM (the Input Method
Manager than can be used in non-EastAsian versions of NT4 or Win9x),
you need the dimm.h header file. But that is rather pointless now as
both Win9x or NT4 have reached their end of life. Active IMM developer
bits are somewhat difficult to find, they were last found at
http://msdn.microsoft.com/downloads/samples/internet/wizard/ . If you
use "autoconfiscated" build, pass the --with-ie55 flag to configure
specifying the location of the ie55_lib directory created by
downloading the IE5.5 headers and libs from the above URL.
