=======
For more information about the port or GLib, GTk+ and the GIMP to
-native Windows, and pre-built binary packages, see
-http://www.iki.fi/tml/gimp/win32/ . "Native" means that we use the
-Win32 API only, and not any POSIX emulation layer except that provided
-by the Microsoft runtime C library. Additionally, a pthreads emulation
-library is used.
-
-To build GLib on Win32, you can use either the Microsoft compiler and
-tools, or gcc. Both the compiler from MSVC 5.0 and from MSVC 6.0 have
-been used successfully. With gcc I mean gcc-2.95 or gcc-2.95.2 as
-distributed by Mumit Khan, running under cygwin-b20.1. To successfully
-use gcc, follow the instructions below. We want to use gcc
--mno-cygwin, i.e. produce executables (.exe and .dll files) that do
-*not* require the cygwin runtime library. This is sometimes called
-"mingw32".
-
-To test the GLib functions, go to the tests subdirectory and enter
-`nmake -f makefile.msc check` or `make -f makefile.cygwin check`.
+native Windows, and pre-built binaries (DLLs), surf to
+http://www.gimp.org/win32/ . "Native" means that we use the Win32 API
+only, and no POSIX (Unix) emulation layer except that provided by the
+Microsoft runtime C library, and a pthreads emulation library.
-If you would want to use the cygwin tools to generate executables that
-*do* use the cygwin runtime, the normal Unix configuration method
-should work as if on Unix. But it won't produce DLLs. At least I
-haven't succeeded in that.
+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
+have been used successfully.
-With a little work, it might be possible to use the ./configure
-mechanism also with a "mingw32" configuration.
+But note that to just *use* GLib on Windows, there is no need to build
+it, prebuilt DLLs are available from the webiste above.
-The following preprocessor macro are used for conditional compilation
+With gcc I mean gcc-2.95.2 as distributed by Mumit Khan, either as a
+mingw version (preferred), or running under cygwin. To successfully
+use gcc, follow the instructions below. We want to use gcc
+-mno-cygwin, i.e. produce executables (.exe and .dll files) that do
+*not* require the cygwin runtime library. This is called "mingw". I
+also use the -fnative-struct flag, which means that in order to use
+the prebuilt DLLs (especially of GTK+), you *must* also use that flag.
+(This flag means that the struct layout is identical to that used by
+MSVC.)
+
+If you would want to use the cygwin tools to generate a GLib that
+*does* use the cygwin runtime, the normal Unix configuration method
+should work as if on Unix. Note that successfully producing shared
+libraries (DLLs) most probably requires you to have a very new libtool
+(from March 2001), and to replace the libtool.m4 included in
+acinclude.m4 with the new one, and to replace ltmain.sh.
+
+It is also possible to use the ./configure mechanism when building for
+a mingw configuration. You should be running cygwin for the configure
+script to work, obviously. The same libtool issue has to be taken into
+account as when building for Cygwin: You most probably should have a
+libtool from March 2001 or so, and replace libtool.m4 (in
+acinclude.m4) and ltmain.sh.
+
+The following preprocessor macros are used for conditional compilation
related to Win32:
- G_OS_WIN32 is defined when compiling for Win32, *and* without
bundled Microsoft C library (msvcrt.dll) and the pthreads-win32
library. For instance, pathnames are in the native Windows syntax.
-- _WIN32 is defined by the compiler
+- G_WITH_CYGWIN is defined if compiling for the Cygwin
+ environment. Note that G_OS_WIN32 is *not* defined in that case, as
+ Cygwin is supposed to behave like Unix. G_OS_UNIX *is* defined when
+ compiling for Cygwin.
-The Win32 port uses the combination with both of those on. As
+- G_PLATFORM_WIN32 is defined when either G_OS_WIN32 or G_WITH_CYGWIN
+ is defined.
+
+The Win32 port of GLib and related software uses only G_OS_WIN32. As
G_OS_WIN32 is defined in glibconfig.h, it is available to all source
files that use GLib (or GTk+, which uses GLib).
Additionally, there are the compiler-specific macros:
-- _MSC_VER is defined when using the Microsoft compiler
- __GNUC__ is defined when using GCC
+- _MSC_VER is defined when using the Microsoft compiler
+
+G_OS_WIN32 implies using the Microsoft C runtime MSVCRT.DLL. GLib or
+software using it is not known to work with the older CRTDLL.DLL
+runtime.
-Some of the usage of these macros used to be a bit mixed up, and had
-to be straightened out when adding the gcc support. In particular, I
-used to check for _MSC_VER in some places where I really wanted to
-check for the Microsoft C library, and those checks has now been
-changed to G_OS_WIN32.
+Building software that use GLib or GTk+
+=======================================
-G_OS_WIN32 implies using the Microsoft C runtime MSVCRT.DLL.
+Even building software that just *use* GLib or GTk+ also require to
+have the right compiler set up the right way, so if you intend to use
+gcc, follow the relevant instructions below in that case, too.
Pthreads library
================
http://sourceware.cygnus.com/pthreads-win32/. The pthreads-win32
snapshot from 1999-05-30 is the one that should be used. Edit the
location of the pthreads library and include files in makefile.msc or
-makefile.cygwin. The pthreads distribution includes the precompiled dll
-and import libraries both for MSVC and gcc.
+makefile.mingw. The pthreads distribution includes the precompiled dll
+and import libraries both for MSVC and gcc. Later versions might also
+work.
The pthreads for Win32 package that the thread support uses supposedly
isn't quite ready yet, and thus threads stuff should not be relied
upon for anything serious.
+Libiconv
+========
+
+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.
+
Where are the makefiles?
========================
If you are building from a CVS snapshot, you will not have any
-makefile.msc or makefile.cygwin file. You should copy the
-corresponding makefile.msc.in or makefile.cygwin.in file to that name,
-and edit the line that sets GLIB_VER to the correct version number.
-
-This is done automatically when an official distribution package is
-built.
-
-Building with MSVC
-==================
-
-If using the Microsoft toolchain, build with `nmake -f
-makefile.msc`. Install with `nmake -f makefile.msc install`.
-
-Building with gcc
-=================
-
-I use the latest and greatest gcc, gcc-2.95.2. 2.95 will also work.
-Earlier version might, but you are on your own.
-
-Read and understand these instruction carefully. If you don't
-understand or can't follow the instructions, you probably shouldn't
-want to build GLib (or GTk+ or GIMP) yourself anyway. Unfortunately,
-even building software that just *use* GLib or GTk+ also require to
-have the right compiler set up the right way, so follow these
-instructions in that case, too.
-
-0) Get and install Cygwin B20.1.
-
- Move the include files and libraries included in Cygwin out of the
- way not to mix things up... (For example, rename
- /cygnus/cygwin-b20/H-i586-cygwin32/i586-cygwin32/lib to
- lib-no-thanks and rename
- /cygnus/cygwin-b20/H-i586-cygwin32/i586-cygwin32/include to
- include-no-thanks.
-
-1) Get gcc 2.95.2 built for Cygwin B20.1 from
- ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/cygwin/gcc-2.95.2/gcc-2.95.2-cygb20.tar.gz
-
- Install it somewhere, let's say G:\gcc-2.95.2 (//g/gcc-2.95.2 when
- in Cygwin). Add //g/gcc-2.95.2/H-i586-cygwin32/bin to your
- PATH. Below,I assume you use bash.
-
- Replace the specs file in
- //g/gcc-2.95.2/H-i586-cygwin32/lib/gcc-lib/i586-cygwin32/2.95.2/specs
- with the following. (The changes are: Define __MSVCRT__, replace
- the "1" versions of the crt files with the "2" ones, replace crtdll
- with msvcrt. Also, extra whitespace squished. )

+Building with MSVC
+==================
- (I haven't checked yet if other small errors I have noticed in
- previous w32api header versions have been corrected.)
-
-3) Now you should build the mingw32 and w32api runtime and import libraries.
-
- Go to //g/src/mingw-runtime-19991107/w32api. Enter:
-
- CC='gcc -mno-cygwin' ./configure i586-pc-mingw32msvc
- make
-
- That should complete in a while. It should produce a lot of .a
- libraries (both import libraries, and a couple of archive
- libraries), and some .o files. I don't trust make install to do
- what I want (especially as I didn't give any --prefix argument to
- the configure...), so I install the stuff manually:
-
- cd lib
- mkdir //g/gcc-2.95.2/H-i586-cygwin32/lib/mingw32
- cp *.a //g/gcc-2.95.2/H-i586-cygwin32/lib/mingw32
- cd ../include
- mkdir //g/gcc-2.95.2/H-i586-cygwin32/i586-cygwin32/include/mingw32
- cp *.h //g/gcc-2.95.2/H-i586-cygwin32/i586-cygwin32/include/mingw32
-
- Now go to ../../mingw, and run the same configure command, and do a
- make:
-
- CC='gcc -mno-cygwin' ./configure i586-pc-mingw32msvc
- make
-
- Then install the mingw32 libraries and headers:
- cp *.a //g/gcc-2.95.2/H-i586-cygwin32/lib/mingw32
- mkdir //g/gcc-2.95.2/H-i586-cygwin32/i586-cygwin32/include/mingw32/sys
- cp include/sys/*.h //g/gcc-2.95.2/H-i586-cygwin32/i586-cygwin32/include/mingw32/sys
- cp include/*.h //g/gcc-2.95.2/H-i586-cygwin32/i586-cygwin32/include/mingw32
-
-
-4) Get an updated set of binutils for cygwin B20.1 from
- ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/cygwin/gcc-2.95.2/binutils-2.9.4-cygb20.tar.gz
- Unpack that in your /cygnus/cygwin-b20 directory. The relevant
- difference is: dlltool now parses GCC generated export directives
- correctly for DATA items.
-
-5) Whew. That hopefully should be it.
-
-Cheers,

-
-Next, go back to the GLib directory and build using `make -f
-makefile.cygwin`. Building the dlls uses the script build-dll which
-is somewhat of a hack. But I couldn't get things working in a cleaner
-way.
+If using the Microsoft toolchain, build with `nmake -f
+makefile.msc`. Install with `nmake -f makefile.msc install`.
