=======

|
|
|
|
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
|
1999-02-25 22:34:25 +01:00
|
|
|
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
|
1999-04-13 23:05:08 +02:00
|
|
|
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
|
1999-04-25 22:52:42 +02:00
|
|
|
tools, or gcc. Both the compiler from MSVC 5.0 and from MSVC 6.0 have
|
|
|
|
been used successfully. With gcc I mean egcs-1.1.2 (as distributed by
|
1999-05-08 10:42:47 +02:00
|
|
|
Mumit Khan), running under cygwin-b20.1. To successfully use gcc,
|
|
|
|
follow the instructions below. I use gcc -mno-cygwin, i.e. the
|
|
|
|
produced executables (.exe and .dll files) do *not* require the cygwin
|
|
|
|
runtime library.
|
1999-02-25 22:34:25 +01:00
|
|
|
|
1999-04-13 23:05:08 +02:00
|
|
|
To test the GLib functions, go to the tests subdirectory and enter
|
1999-05-06 19:33:15 +02:00
|
|
|
`nmake -f makefile.msc check` or `make -f makefile.cygwin check`.
|
1999-04-13 23:05:08 +02:00
|
|
|
|
1999-04-24 15:52:51 +02:00
|
|
|
If you would want to use the cygwin tools to generate executables that
|
1999-04-25 22:52:42 +02:00
|
|
|
*do* use the cygwin runtime, the normal Unix configuration method
|
1999-05-08 10:42:47 +02:00
|
|
|
should work as if on Unix. But it won't produce DLLs. At least I
|
|
|
|
haven't succeeded in that.
|
1999-01-19 22:13:59 +01:00
|
|
|
|
|
|
|
With a little work, it might be possible to use the ./configure
|
1999-04-24 15:52:51 +02:00
|
|
|
mechanism also with a "mingw32" configuration.
|
1999-01-19 22:13:59 +01:00
|
|
|
|
|
|
|
The following preprocessor macros are used for conditional compilation
|
|
|
|
related to Win32:
|
|
|
|
|
|
|
|
- WIN32 is defined when compiling for the Win32 platform, regardless
|
1999-02-25 22:34:25 +01:00
|
|
|
if using the X11 or Win32 windowing API (in the case of GLib, this
|
|
|
|
dimension isn't significant), regardless whether using a more or
|
|
|
|
less complete POSIX emulation runtime layer (like Cygwin) or not.
|
1999-01-19 22:13:59 +01:00
|
|
|
|
|
|
|
- NATIVE_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
|
|
|
|
1999-04-24 15:52:51 +02:00
|
|
|
The Win32 port uses the combination with both of those on.
|
1999-01-19 22:13:59 +01:00
|
|
|
|
1999-04-24 15:52:51 +02:00
|
|
|
Additionally, there are the compiler-specific macros:
|
|
|
|
- _MSC_VER is defined when using the Microsoft compiler
|
|
|
|
- __GNUC__ is defined when using GCC (i.e. egcs)
|
1999-01-19 22:13:59 +01:00
|
|
|
|
1999-04-24 15:52:51 +02:00
|
|
|
Some of the usage of these macros was 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
|
1999-05-06 19:33:15 +02:00
|
|
|
NATIVE_WIN32. NATIVE_WIN32 should maybe be renamed to USE_MSVCRT.

Pthreads library
|
|
|
|
================
|
|
|
|
|
|
|
|
Before building you must get the pthreads library for Win32 from
|
|
|
|
http://sourceware.cygnus.com/pthreads-win32/. The pthreads-win32
|
|
|
|
snapshot from 1999-04-07 is the one that should be used. Edit the
|
|
|
|
location of the pthreads library and include files in makefile.msc or
|
|
|
|
makefile.cygwin. The ptreads distribution includes the precompiled dll
|
|
|
|
and import libraries both for MSVC and gcc.
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
Building with MSVC
|
|
|
|
==================
|
|
|
|
|
|
|
|
If using the Microsoft toolchain, build with `nmake -f
|
|
|
|
makefile.msc`. Install with `nmake -f makefile.msc install`.
|

|
1999-05-08 10:42:47 +02:00
|
|
|
Building with gcc
|
|
|
|
=================
|
|
|
|
|
|
|
|
The gcc support was added quite recently, but seems to work. Debugging
|
|
|
|
with gdb works. I prefer to use the msvcrt runtime and not the default
|
|
|
|
crtdll. Especially, as the pthread library also uses msvcrt, using
|
|
|
|
crtdll would probably not be a good idea at all. Using msvcrt can be
|
|
|
|
achieved by applying the following diff to the specs file, which
|
|
|
|
typically is installed as
|
|
|
|
C:/cygnus/cygwin-b20/H-i586-cygwin32/lib/gcc-lib/i586-cygwin32/egcs-2.91.66/specs.
|
|
|
|
|
|
|
|
Sorry for the illegibility of this diff, but the specs file is like
|
1999-05-12 20:59:49 +02:00
|
|
|
that... This patch replaces -lcrtdll with -lmsvcrt, replaces crt1 with
|
|
|
|
crt2, removes -lmoldname (because that might pull in crtdll.dll), and
|
|
|
|
defines __MSVCRT__.

You should also fix the definition of _dev_t in the header
|
|
|
|
mingw32/sys/types.h to correspond to what it actually is used by
|
|
|
|
msvcrt.dll. It should be unsigned int, not short. Otherwise stat()
|
|
|
|
calls will fail.
|
|
|
|
|
|
|
|
You also will have to get the mingw32 source snapshot from
|
|
|
|
http://www.geocities.com/Tokyo/Towers/6162/mingw32_980701_tar.gz (this
|
|
|
|
is the source to the "mingw32" part of what's included with Mumit
|
|
|
|
Khan's egcs-1.1.2. Unpack it and fix the prototype and call to
|
|
|
|
__getmainargs() in init.c to include one more parameter, an int *,
|
|
|
|
which should be passed the address of a zero int. Remake dllcrt2.o
|
|
|
|
(which is the file which gets linked into dlls when using msvcrt, as
|
|
|
|
per the specs file above). Code snippets below:
|
|
|
|
|
|
|
|
...
|
|
|
|
#ifdef __MSVCRT__
|
|
|
|
extern void __getmainargs(int *, char***, char***, int, int *);
|
|
|
|
#else
|
|
|
|
...
|
|
|
|
#ifdef __MSVCRT__
|
|
|
|
int newmode = 0;
|
|
|
|
(void) __getmainargs(&_argc, &_argv, &dummy_environ, _CRT_glob, &newmode);
|
|
|
|
#else
|
|
|
|
...
|
|
|
|
|
|
|
|
Next, build using `make -f makefile.cygwin`.
