General
=======
For prebuilt binaries (DLLs and EXEs) and developer packages (headers,
import libraries) of GLib, GTK+, GIMP etc for Windows, surf to
-http://www.gimp.org/win32/ . They are for "native" Windows meaning
-they use the Win32 API and Microsoft C runtime library only, no POSIX
-(Unix) emulation layer (like Cygwin).

To build GLib on Win32, you can use either gcc or the Microsoft
compiler and tools. Both the compiler from MSVC 5.0 and from MSVC 6.0
But note that to just *use* GLib on Windows, there is no need to build
it yourself. Prepackaged runtime and developer packages are available
from the webiste above. On Unix, it is quite normal that system admins

Building software that use GLib or GTK+
=======================================
Tor uses gcc with the -mms-bitfields flag (used to be called
-fnative-struct in gcc 2.x), which means that in order to use the
prebuilt DLLs (especially of GTK+), if you compile your code with gcc,
-you *must* also use that flag. (This flag means that the struct layout
+you *must* also use that flag. This flag means that the struct layout
rules are identical to those used by MSVC. This is essential if the
same DLLs are to be usable both from gcc- and MSVC-compiled code. This
-definitely is something one wants.)
+definitely is something one wants.
Building GLib
=============
Again, first decide whether you really want to do this.
-Before building GLib you must also have the libiconv library, either
-from the same website mentioned above, or from it's homepage at
-http://clisp.cons.org/~haible/packages-libiconv.html. Libiconv has
-makefiles for building with MS Visual C only, but as it is one source
-file only, building it "by hand" with gcc isn't hard.
-
-You must also have the "intl" library from GNU tettext 0.10.40 (or
-later). Get a prebuilt version from the website mentioned above.
-
-Edit the correct paths to those libraries in build/win32/module.defs
-as appropriate.
+Before building GLib you must also have the libiconv library and GNU
+gettext. Get prebuilt binaries of libiconv (1.9.1 or newer), and
+gettext-runtime (0.13.1 or newer) from www.gimp.org/win32/downloads.html.
-Where are the makefiles?
-========================
+Autoconfiscated build (with gcc)
+================================
-If you are building from a CVS snapshot, you will not have any
-makefile.mingw or makefile.msc files. You should copy the
-corresponding makefile.mingw.in or makefile.msc.in file to that name,
-and replace any @...@ strings with the correct value.
-
-This is done automatically when an official GLib source distribution
-package is built, so if you get GLib from a source distribution
-package, there should be makefile.mingw and makefile.msc files ready
-to use (after some editing).
-
-Building GLib with gcc
-======================
-
-Tor uses gcc 3.2. Version 2.95.3 also works.
+Tor uses gcc 3.3.1. Somewhat earlier or later versions presumably also
+work.
You can either use gcc running on Cygwin, or the "pure" mingw
gcc. Using the latter might work better, or at least did at some
-point.
-
-Fetch the latest version of gcc for mingw and the msvcrt runtime, from
-www.mingw.org.
-
-Set up your PATH so that the gcc from the bin directory that got
-created above is the one that gets used. Even if you run the mingw
-gcc, you still want to have Cygwin to run make in.
+point. You should be running Cygwin, or maybe cross-compiling from
+real Unix, for the configure script to work, obviously. It is also
+possible to use MSYS.
-Then run make -f makefile.mingw. Install the resulting DLLs somewhere
-in your PATH. You can either keep the headers and import libraries
-where they are, or install them somewhere else. There are no rules in
-the makefile.mingws for installing, it is up to you where to put them.
+If you want to use mingw's gcc, install gcc, Win32 headers and
+binutils from www.mingw.org. Set up your PATH so that the mingw gcc is
+the one that gets used, and not Cygwin's gcc. Even if you run the
+mingw gcc, you still want to have Cygwin to run make in.
-Autoconfiscated build
-=====================
-
-It is also possible to use the auto*, ./configure and libtool
-mechanism when building with gcc. You should be running Cygwin, or
-maybe cross-compiling from real Unix, for the configure script to
-work, obviously. (It should also be possible to use MSYS.) Tor invokes
-configure using:
+Tor invokes configure using:
CC='gcc -mcpu=pentium3' CPPFLAGS='-I/target/include'
CFLAGS=-O3 LDFLAGS='-L/target/lib' ./configure --with-libiconv

+(on a single line). The /target/include mentioned contains the header
+files for libintl and libiconv, and the (import) libraries are in
+/target/lib. This happens to be in the same tree where he configures
+GLib to be installed, but doesn't have to be.

+Please note that the ./configure mechanism should not blindly be used
+to build a GLib to be distributed to other developers because it
produces a compiler-dependent glibconfig.h (and config.h, but that
shouldn't matter, as it isn't seen by GLib-using applications). For
instance, the typedef for gint64 is long long with gcc, but __int64
Except for this and a few other minor issues, there really shouldn't
be any reason to distribute separate GLib headers and DLLs for gcc and
-MSVC users, as both compilers generate code that uses the same C
-runtime library. Thus one either has to manually edit glibconfig.h
-afterwards, or use the supplied glibconfig.h.win32. This has been
-produced by running configure twice, once using gcc and once using
-MSVC, and merging the resulting files with diff -D.
-
-There might be other hickups when using auto* and configure to build
-with gcc. Lately Tor has used auto*/configure/libtool exclusively when
-building GLib, GTK+, GIMP etc on Win32, and it seems to work well
-(with some patches applied to the current CVS libtool...).
-
-The hand-written makefile.{mingw,msc} files, and the stuff in the
-"build" subdirectory, produce DLLs and import libraries that match
-what Makefile.am and libtool produces. For GLib, the DLL is called
+MSVC users, as the compilers generate code that uses the same C
+runtime library. The DLL generated by either compiler is binary
+compatible with the other one. Thus one either has to manually edit
+glibconfig.h afterwards, or use the supplied glibconfig.h.win32 which
+has been produced by running configure twice, once using gcc and once
+using MSVC, and merging the resulting files with diff -D.
+
+For GLib, the DLL is called
libglib-2.0-0.dll, and the import libraries libglib-2.0.dll.a and
glib-2.0.lib. Note that the "2.0" is part of the "basename" of the
library, it is not something that libtool has tucked on. The -0 suffix
new libtool. (And a new libtool probably requires rather new autoconf
and automake.) Tor hasn't tested this in a while, either.
+Cross-compiling
+===============
+
+It is possible to build GLib using a cross compiler. See
+docs/reference/glib/html/glib-cross-compiling.html (part of the
+GLib reference manual) for more information.
+
Building with MSVC
==================
-All the MSVC makefiles are for the command line build with nmake.
-If you want to use the VC-UI you can simply create wrapper .dsp
-makefiles (read the VC docs how to do so).
+If you are building from a CVS snapshot, you will not have any
+makefile.msc files. You should copy the corresponding makefile.msc.in
+file to that name, and replace any @...@ strings with the correct
+value.
+
+This is done automatically when an official GLib source distribution
+package is built, so if you get GLib from a source distribution
+package, there should be makefile.msc files ready to use (after some
+editing).
+
+The hand-written makefile.msc files, and the stuff in the "build"
+subdirectory, produce DLLs and import libraries that match what the
+so-called autoconfiscated build produces.
+
+All the MSVC makefiles are for the command line build with nmake. If
+you want to use the VC-UI you can simply create wrapper .dsp makefiles
+(read the VC docs how to do so).
Some modules may require Perl to auto-generate files. The goal (at
least Hans's) is to not require any more tools.

Required libraries (not build from cvs)
-==================
+------------------
libintl (gnu-intl), libiconv
libtiff, libpng, zlib, libjpeg
are available pre-built from the website mentioned above.
Versioning
-==========
+----------
Instead of the Unix and auto* way of tracking versions and resolving
dependencies (configure; make; make install) involving autoconf,
automake, libtool and friends the MSVC build uses a different
when producing his zipfiles with prebuilt GLib, GTK+ etc).
Special Files
-=============
+-------------
config.h.win32.in : @XXX_MAJOR_VERSION@ needs to be replaced by
the current version/build number. The resulting file is to be saved
as 'config.h.win32'. This should be automatically done if a package
Directory Structure
-===================
+-------------------
all modules should be build in a common directory tree otherwise you
need to adapt the file 'module.defs'. They are listed here in increasing
dependencies order.
