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.
|
1999-02-25 22:34:25 +01:00
|
|
|
|
1999-04-24 15:52:51 +02:00
|
|
|
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
|
1999-11-11 00:08:37 +01:00
|
|
|
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".
|
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
|
|
|
|
1999-11-11 00:08:37 +01:00

|
The following preprocessor macro are used for conditional compilation
|
|
|
|
|
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
|
|
|
|
1999-11-11 00:08:37 +01:00
|
|
|
- _WIN32 is defined by the compiler
|
|
|
|
|
|
|
|
|
|
The Win32 port uses the combination with both of those on. As
|
|
|
|
|
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:
|
|
|
|
|
- _MSC_VER is defined when using the Microsoft compiler
|
1999-07-21 21:18:03 +02:00
|
|
|
- __GNUC__ is defined when using GCC
|
1999-01-19 22:13:59 +01:00
|
|
|
|
1999-06-21 00:20:43 +02:00
|
|
|
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
|
1999-11-11 00:08:37 +01:00
|
|
|
changed to G_OS_WIN32.
|
|
|
|
|
|
|
|
|
|
G_OS_WIN32 implies using the Microsoft C runtime MSVCRT.DLL.

Building software that use GLib or GTk+
|
|
|
|
|
=======================================
|
|
|
|
|
|
|
|
|
|
Unfortunately, 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.
|
|
|
|
|
|
1999-05-08 10:42:47 +02:00
|
|
|
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
|
1999-06-21 00:20:43 +02:00
|
|
|
makefile.cygwin. The pthreads distribution includes the precompiled dll
|
1999-05-08 10:42:47 +02:00
|
|
|
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.
|
|
|
|
|
|
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
|
|
|
|
|
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.
|
|
|
|
|
|
1999-05-08 10:42:47 +02:00
|
|
|
Building with MSVC
|
|
|
|
|
==================
|
|
|
|
|
|
|
|
|
|
If using the Microsoft toolchain, build with `nmake -f
|
|
|
|
|
makefile.msc`. Install with `nmake -f makefile.msc install`.
|
1999-05-08 10:43:58 +02:00
|
|
|
|
1999-05-08 10:42:47 +02:00
|
|
|
Building with gcc
|
|
|
|
|
=================
|
|
|
|
|
|
1999-11-11 00:08:37 +01:00
|
|
|
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.
|
1999-07-21 21:18:03 +02:00
|
|
|
|
2000-02-03 00:39:32 +01:00
|
|
|
Read these instruction carefully and understand them. If you don't
|
1999-07-31 23:45:21 +02:00
|
|
|
understand or can't follow the instructions, you probably shouldn't
|
2000-02-03 00:39:32 +01:00
|
|
|
want to build GLib (or GTk+ or GIMP) yourself anyway.
|

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
|
1999-11-14 22:48:31 +01:00
|
|
|
PATH. I assume you use bash below.
|
1999-11-11 00:08:37 +01:00
|
|
|
|
|
|
|
|
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. )

|
|

it is, though, there doesn't seem to be any gprof command in cygwin.

(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
|
2000-02-23 21:09:16 +01:00
|
|
|
cp crt2.o crtdll2.o //g/gcc-2.95.2/H-i586-cygwin32/lib/mingw32
|
1999-11-11 00:08:37 +01:00
|
|
|
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.
|
|
|
|
|
|
1999-07-21 21:18:03 +02:00
|
|
|
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.
