Installation on Windows

Install MinGW

Download MinGW-3.2.0-rc-3 or later from http://sourceforge.net/projects/mingw Install it into

C:/xxx/msys/1.0/mingw

(where /xxx/ is the top-level path you want to use, I use Nicola/GNUstep so I install it into C:/Nicola/GNUstep/msys/1.0/mingw) (earlier versions of MinGW won't work)

Install msys

Download MSYS-1.0.10 or later from the same site. Install it into C:/xxx/msys/1.0 The postinstall script should ask you for the mingw location, then detect it and be happy that it's there and all is setup properly.

Install msys developer toolkit

Download msysDTK-1.0.1 or later from the same site. Install it into

C:/xxx/msys/1.0

Now your MSYS/MinGW system should be setup! Go around and make sure you know how to use the Unix-like shell. Log into it and work in it.

Install GNUstep make

go in core/make and do

./configure --prefix=/C/xxx/GNUstep
make
make install

Setup your GNUstep environment

(you will need to do the same every time you start up your MSYS shell to do development)

. /C/xxx/GNUstep/System/Library/Makefiles/GNUstep.sh

Also, set HOMEPATH, HOMEDRIVE and HOME ... add the following lines to your ~/.profile:

export HOMEDRIVE=C:
export HOMEPATH=/home/Nicola
export HOME=/C/xxx/msys/1.0/home/Nicola
. /C/xxx/GNUstep/System/Library/Makefiles/GNUstep.sh

(obviously replacing 'Nicola' with your Login name) (not sure if this setting of HOMEDRIVE etc is really required, will investigate)

Install the ObjC runtime

Actually, recent versions of gcc (3.2+) have a working libobjc on Windows. Nevertheless this step is necessary (at least on Windows 2000) unless you want some strange errors concerning NSAutoreleasePool etc.

First make sure to delete the old libobjc files

find /C/xxx/GNUstep/ -iname "libobjc*" -exec rm -i {} \;

Then cd to dev-libs/libobjc in your cvs checkout directory and install it.

make
make install

Reinstall GNUstep make (with ObjC this time)

go in core/make and reconfigure/recompile again so that gnustep-objc is detected:

make distclean
./configure
make 
make install

gnustep-make should have detected your custom libobjc.

Install ffcall

Download ffcall from the GNUstep website, or from here: ftp://ftp.santafe.edu/pub/gnu/ffcall-1.10.tar.gz, and type:

./configure --prefix=$GNUSTEP_SYSTEM_ROOT
make
make install

Note: The configure script of ffcall-1.10 is broken for Windows 2000. You have to apply a patch: http://lists.gnu.org/archive/html/discuss-gnustep/2005-03/msg00258.html

Alternatively, a zip containing a precompiled copy of ffcall-1.9 is availabe here: ftp://ftp.gnustep.org/pub/gnustep/binaries/windows/mingw-libs/ffcall-1.9-gnustep.zip

Unzip it into $GNUSTEP_SYSTEM_ROOT/Library.

Install additional libs

Download the following packages:

Download libintl

libintl-0.11.5-2-bin.zip
libintl-0.11.5-2-lib.zip

Download libiconv

libiconv-1.8.1-bin.zip 
libiconv-1.8.1-lib.zip 

Download zlib

zlib-1.2.2-bin.zip
zlib-1.2.2-lib.zip

from http://gnuwin32.sourceforge.net, and install them. To install them, simply unzip them into

/C/xxx/msys/1.0/mingw.

Install XML support

XML support not working yet, step omitted

Install GNUstep base

go in gnustep-base, and type

./configure --disable-xml
make
make install

Install additional GUI libs

for the gui, download and install the following packages:

Download jpeg

 jpeg-6b-3-bin.zip
 jpeg-6b-3-dep.zip
 jpeg-6b-3-lib.zip

Download tiff

 tiff-3.7.1-bin.zip
 tiff-3.7.1-dep.zip
 tiff-3.7.1-lib.zip

Download libpng

 libpng-1.2.8-bin.zip
 libpng-1.2.8-dep.zip
 libpng-1.2.8-lib.zip

The process is always the same: download the zip file from the gnuwin32 website, then unzip them into

/C/xxx/msys/1.0/mingw.

Install GNUstep gui

go in the gui, and type:

 ./configure
 make
 make install

Install GNUstep back

go in back, and type:

 ./configure
 make
 make install

Check the installation

go in a simple gui application (examples/gui a very good starting point), compile and run it. :-)
