Merge in current Win32 version. Almost no Unix code touched.
* README.win32: More text.
* config.h.win32 glibconfig.h.win32: Update to match the
corresponding generated files on Unix.
* makefile.msc: Update with new source files, and gthread
library. Use the compiler flag -MD instead of using -D_DLL and
"/nodefaultlib:libc msvcrt.lib" in the link phase.
* glib.def: Include new functions, drop removed ones.
* glib.h: Add comments about main loop and polling on Win32. (In
general, it's only for the GIMP's use.) Add Win32 IO Channel
functions. Remove the obsoleted old IO Channel stuff (which was
in #if 0 already).
* giowin32.c: New file.
* gmain.c: Include config.h, conditionalize <sys/time.h>
inclusion. Add g_poll implementation for Win32 (only for the
GIMP's needs for now, it's hard or even impossible to be as clean
and generic as on Unix). Implement g_get_current_time on Win32. If
threads aren't supported, don't try to wake up main thread's
loop. On Win32, use a semaphore and not a pipe to wake up the main
loop.
* gmessages.c: On Win32, allocate a console window if the standard
output handle is invalid before writing to stdout, and reopen stdout
to that console window.
* giochannel.c: Conditionalize unistd.h inclusion. Some indentation
cleanup.
* gstrfuncs.c: Include <signal.h>.
* gutils.c: On Win32, also check the HOMEDRIVE and HOMEPATH
environment variables.
* gmodule-dl.c gmodule-dld.c: In
_g_module_build_path, don't add the "lib" prefix and
".so" or ".sl" suffix if already there.
* gmodule-win32.c: Likewise for the ".dll" suffix.
* gthread-posix.c: Conditionalize <sys/time.h> inclusion.

For more information about the port or GLib, GTk+ and the GIMP to
|
2000-12-27 21:56:15 +01:00
|
|
|
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.

|
|
|
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
|
2000-10-23 21:17:41 +02:00
|
|
|
have been used successfully.
|
|
|
|
|
2000-12-27 21:56:15 +01:00
|
|
|
But note that to just *use* GLib on Windows, there is no need to build
|
|
|
|
it, prebuilt DLLs are available from the webiste above.
|
2000-07-05 00:52:51 +02:00
|
|
|
|
2000-12-27 21:56:15 +01:00
|
|
|
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.
|
2000-07-22 13:54:19 +02:00
|
|
|
(This flag means that the struct layout is identical to that used by
|
|
|
|
MSVC.)
|

|
|
|
|
2001-03-09 22:55:06 +01:00
|
|
|
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
|
1999-11-11 00:08:37 +01:00
|
|
|
related to Win32:
|
1999-01-19 22:13:59 +01:00
|
|
|
|
1999-11-11 00:08:37 +01:00
|
|
|
- G_OS_WIN32 is defined when compiling for Win32, *and* without
|
1999-02-25 22:34:25 +01:00
|
|
|
any POSIX emulation, other that to the extent provided by the
|
1999-05-08 10:42:47 +02:00
|
|
|
bundled Microsoft C library (msvcrt.dll) and the pthreads-win32
|
|
|
|
library. For instance, pathnames are in the native Windows syntax.
|
1999-01-19 22:13:59 +01:00
|
|
|
|
2000-12-27 21:56:15 +01:00
|
|
|
- G_WITH_CYGWIN is defined if compiling for the Cygwin
|
|
|
|
environment. Note that G_OS_WIN32 is *not* defined in that case, as
|
2001-03-09 22:55:06 +01:00
|
|
|
Cygwin is supposed to behave like Unix. G_OS_UNIX *is* defined when
|
|
|
|
compiling for Cygwin.
|
|
|
|
|
|
|
|
- G_PLATFORM_WIN32 is defined when either G_OS_WIN32 or G_WITH_CYGWIN
|
|
|
|
is defined.
|
1999-11-11 00:08:37 +01:00
|
|
|
|
2000-12-27 21:56:15 +01:00
|
|
|
The Win32 port of GLib and related software uses only G_OS_WIN32. As
|
1999-11-11 00:08:37 +01:00
|
|
|
G_OS_WIN32 is defined in glibconfig.h, it is available to all source
|
|
|
|
files that use GLib (or GTk+, which uses GLib).
|
1999-01-19 22:13:59 +01:00
|
|
|
|
1999-04-24 15:52:51 +02:00
|
|
|
Additionally, there are the compiler-specific macros:
|
1999-07-21 21:18:03 +02:00
|
|
|
- __GNUC__ is defined when using GCC
|
2000-12-27 21:56:15 +01:00
|
|
|
- _MSC_VER is defined when using the Microsoft compiler
|
1999-11-11 00:08:37 +01:00
|
|
|
|
2000-10-23 21:17:41 +02:00
|
|
|
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.

Building software that use GLib or GTk+
|
|
|
|
=======================================
|
|
|
|
|
2000-12-27 21:56:15 +01:00
|
|
|
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
|
|
|
|
================
|
|
|
|
|
|
|
|
Before building you must get the pthreads library for Win32 from
|
|
|
|
http://sourceware.cygnus.com/pthreads-win32/. The pthreads-win32
|
1999-06-21 00:20:43 +02:00
|
|
|
snapshot from 1999-05-30 is the one that should be used. Edit the
|
1999-05-08 10:42:47 +02:00
|
|
|
location of the pthreads library and include files in makefile.msc or
|
makefile.mingw.in tests/makefile.mingw.in Rename makefile.cygwin(.in) to
2000-05-13 Tor Lillqvist <tml@iki.fi>
* makefile.mingw.in
* tests/makefile.mingw.in
* build-dll: Rename makefile.cygwin(.in) to
makefile.mingw(.in), which better describes what it is. Move the
build of gmodule, gthread and gobject DLLs to makefiles in those
directories. Move resource file handling and build number bump to
build-dll, where it sits much cleaner.
* README.win32
* Makefile.am (EXTRA_DIST): Update accordingly.
* glib.h: Add G_PI, G_PI_2, G_PI_4, G_E, G_LN2, G_LN10 and
G_SQRT2. M_PI etc aren't necessarily in <math.h> in strict ISO C
implementations.
* glib.def: Add g_strcanon.
* gtree.c (g_tree_node_rotate_left): Remove unused variables.
* gwin32.c (g_win32_opendir): Remove unneeded statement.
gmodule:
* makefile.mingw.in: New file, with gmodule stuff
moved from ../makefile.mingw.in.
* Makefile.am: Add to EXTRA_DIST, and add rule to make makefile.mingw.
gobject:
* makefile.mingw.in
* gobject.def
* gobject.rc.in: New files, for Win32 (mingw) build.
* Makefile.am: Add to EXTRA_DIST. Add rules to produce the
corresponding non-*.in files.
* gtype.h: (Win32:) Mark _g_type_fundamental_last for
export/import from DLL.
gthread:
* makefile.mingw.in: New file, with gthread stuff moved from
../makefile.mingw.in.
* Makefile.am: Add to EXTRA_DIST, add rule to build makefile.mingw.
2000-05-13 21:30:58 +02:00

|
|
makefile.mingw. The pthreads distribution includes the precompiled dll
|
2000-10-23 21:17:41 +02:00
|
|
|
and import libraries both for MSVC and gcc. Later versions might also
|
|
|
|
work.
|
1999-05-08 10:42:47 +02:00
|
|
|
|
|
|
|
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.
|
|
|
|
|
1999-06-21 00:20:43 +02:00
|
|
|
Where are the makefiles?
|
|
|
|
========================
|
|
|
|
|
|
|
|
If you are building from a CVS snapshot, you will not have any
|
2000-07-05 00:52:51 +02:00
|
|
|
makefile.mingw or makefile.msc file. You should copy the corresponding
|
|
|
|
makefile.mingw.in or makefile.msc.in file to that name, and edit the
|
|
|
|
line that sets GLIB_VER to the correct version number.
|
1999-06-21 00:20:43 +02:00
|
|
|
|
2000-10-23 21:17:41 +02:00
|
|
|
This is done automatically when an official GLib source distribution
|
|
|
|
package is built.

Building GLib with gcc
|
|
|
|
======================
|
1999-05-08 10:42:47 +02:00
|
|
|
|
2000-10-23 21:17:41 +02:00
|
|
|
I use the latest gcc, gcc-2.95.2. Version 2.95 will most probably also
|
|
|
|
work.
|
1999-07-21 21:18:03 +02:00
|
|
|
|
2000-03-26 22:56:07 +02:00
|
|
|
You can either use gcc running on cygwin, or the "pure" mingw
|
2000-07-05 00:52:51 +02:00
|
|
|
gcc. Using the latter is much easier.
|
|
|
|
|
|
|
|
Just fetch the latest version of gcc for mingw and the msvcrt runtime,
|
|
|
|
currently from
|
2000-03-26 22:56:07 +02:00
|
|
|
ftp://ftp.nanotech.wisc.edu/pub/khan/gnu-win32/mingw32/snapshots/gcc-2.95.2-1/
|
2000-07-05 00:52:51 +02:00
|
|
|
.
|
|
|
|
|
|
|
|
Download the three zip archives: the gcc-<version>-msvcrt,
|
2000-03-26 22:56:07 +02:00
|
|
|
mingw-msvcrt-<timestamp> and binutils-<timestamp>-msvcrt, and unpack
|
2000-07-05 00:52:51 +02:00
|
|
|
them in a suitable directory.
|
|
|
|
|
|
|
|
Set up your PATH so that the gcc from the bin directory that got
|
|
|
|
created above is the one that gets used. You can skip steps 1--5
|
|
|
|
below. Even if you run the mingw gcc, you still want to have cygwin to
|
|
|
|
run make in.
|
2000-03-26 22:56:07 +02:00
|
|
|
|
2000-10-23 21:17:41 +02:00
|
|
|
If you want to run a cygwin-based gcc, it gets a bit more
|
2000-03-26 22:56:07 +02:00
|
|
|
complicated. We still want gcc to produce code that does not use
|
2000-07-05 00:52:51 +02:00
|
|
|
cygwin, but the msvcrt runtime. The way to do this can be quite
|
|
|
|
complex, and the instructions are not included here. Contact me if you
|
|
|
|
want some possibly outdated, misleading and incomplete advice.
