and automake.) Tor hasn't tested this in a while.
Building with MSVC
==================
If using the Microsoft toolchain, build with `nmake -f
makefile.msc`.
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.
Build with:
nmake -f makefile.msc
or
nmake -f makefile.msc DEBUG=1
[
The former will create 'release' versions of the DLLs. If you
plan to distribute you DLLs please use this command. The latter
will create DLLs with debug information _and_ link them with
msvcrtd.dll instead of msvcrt.dll.
Beware: There are known problems with mixing DLLs in one
application, which are build against different runtimes.
Especially the index-to-file mapping used by 'unix-style' file
operation - _open() _pipe() etc. - breaks sometimes in strange
ways (for example the Gimp plug-in communication).
]
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
approach.
The core of it's versioning is the file build/win32/module.defs.
It contains entries of the form MODULE_VER, e.g.:
GLIB_VER = 2.0
LIBICONV_VER = 1.3
and the placement of these modules defined as MODULE, e.g.:
GLIB = $(TOP)/glib
LIBICONV = $(TOP)/libiconv-$(LIBICONV_VER)
whereas TOP is defined as the relative path from the respective
module directory to your top build directory. Every makefile.msc
needs to define TOP before including the common make file part
make.msc, which than includes module.defs, like:
TOP = ../..
!INCLUDE $(TOP)/glib/build/win32/make.msc
(Taken from gtk+/gdk/makefile.msc)
With this provision it is possible to create almost placement
independent makefiles without requiring to 'install' the libraries and
headers into a common place (as it is done on Unix, and as Tor does
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
gets build on the Unix platform.
makefile.msc.in : @XXX_MAJOR_VERSION@ to be replaced. Save as
makefile.msc.
<module>.def : every function which should be used from the outside of
a dll needs to be marked for 'export'. It is common that one needs to change
these files after some api changes occured. If there are variables to be
exported another mechanism is needed, like :
#ifdef G_OS_WIN32
# ifdef GDK_COMPILATION
# define GDKVAR __declspec(dllexport)
# else
# define GDKVAR extern __declspec(dllimport)
# endif
#else
# define GDKVAR extern
#endif
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.
