[mapserver-users] Java MapScript Win32 DLL

[Andrew Collins]

Steps taken:

1. Compiled MapServer with gcc using MinGW and MSYS.

2. Generated MapScript C and Java code with swig.

3. Produced dll with dlltool and gcc using MinGW and MSYS.

I have had absolutely no luck using the dll. This is the
first time that I've used MinGW, MSYS, dlltool, gcc and
swig to produce a dll. I'm certain that I have missed
some fundamental steps somewhere. Here is a listing of
the files I've used, the commands I've executed and the
changes to the 3.6.1 distribution that I've made to
produce the "mapscript_java.dll" file:

A batch file to download all the necessary files, makes
use of "curl", but "wget" would probably work, too...

==

1. Install MinGW
   E:\win32app\MinGW

2. Install MSYS
   E:\win32app\MinGW\1.0

3. Unzip Swig
   E:\win32app\SWIG-1.3.15

4. Unzip MapServer
   E:\win32app\MinGW\1.0\bin\%USERPROFILE%\mapserver-3.6.1

5. Unzip required libraries
   gdlib-1.8.4-lib.zip
   freetype-2.1.2-1-lib.zip
   libjpeg-6b-lib.zip
   libpng-1.2.4-1-lib.zip
   xpm-3.4k-1-lib.zip
   zlib-1.1.4-lib.zip
   regex-0.12-lib.zip

   E:\win32app\MinGW\1.0\bin\%USERPROFILE%\mapserver-3.6.1\include
   E:\win32app\MinGW\1.0\bin\%USERPROFILE%\mapserver-3.6.1\lib
   E:\win32app\MinGW\1.0\bin\%USERPROFILE%\mapserver-3.6.1\manifest

6. Run MSYS

==

$ cd
$ cd mapserver-3.6.1
$ mv lib/libgd.dll.a lib/libgd_dll.a
$ mv mapogr.cpp mapogr.c
$ vi configure

  Change two lines:

GD_CHECKLIB=c

  to:

GD_CHECKLIB=gd

$ ./configure --with-jpeg=. --with-gd=. --with-freetype=. --with-zlib=.
--with-png=. --without-pdf --without-tiff --without-eppl --without-wms
--without-php

$ vi Makefile

  Change line:

mapogr.o: mapogr.cpp
    $(CXX) -c $(CFLAGS) mapogr.cpp -o mapogr.o

  to:

#mapogr.o: mapogr.cpp
#    $(CC) -c $(CFLAGS) $< -o $@

$ make lib
$ cd mapscript
$ cd java
$ cp ../mapscript.i .

Use the following "Makefile"

The resulting "mapscript_java.dll" doesn't work.
