gcj compilation problem: 'undefined reference to org::eclipse::swt::events:...'

[Adam Papp <adampapp at yahoo dot com>]

Has anyone had any luck compiling the eclipse examples using gcj? 
I have been trying for a month to compile the java examples that came
 with Eclipse using MingW gcc 3.3 on Windows.

My directory tree looks like this:
C:\Yello\Compiler\gcc-3.3\bin\*
C:\Yello\Compiler\swt\win32\lib\*
C:\Yello\Compiler\swt\win32\swt-2133\*

So, I copied the java files for the layoutexample
(org\eclipse\swt\examples\layoutexample\) 
to the directory I'm using for compilation, C:\Yello.
I have the following files in C:\Yello 
   -swt-win32-2133.dll is in the compilation directory and also in
System32
   -Tab.java 
   -RowLayoutTab.java 
   -LayoutExample.java 
   -GridLayoutTab.java 
   -FormLayoutTab.java 
   -FillLayoutTab.java
   -compile.bat

My batch file consists of
------------------------------------
setlocal
set PROG=LayoutExample

set SWT_BASE_DIR=C:\Yello\Compiler\swt\win32
set SWT_GCJ_LIB_DIR=C:\Yello\Compiler\swt\win32\lib
set SWT_JAVA_LIB_DIR=C:\Yello\Compiler\swt\win32\swt-2133

C:\Yello\Compiler\gcc-3.3\bin\gcj --main=%PROG%
--classpath=%SWT_JAVA_LIB_DIR%\swt.jar -s -o %PROG%.exe %PROG%.java
Tab.java RowLayoutTab.java GridLayoutTab.java FormLayoutTab.java
FillLayoutTab.java %SWT_GCJ_LIB_DIR%\SWTMessages.o
%SWT_GCJ_LIB_DIR%\SWTImageLoaders.o -L%SWT_GCJ_LIB_DIR% -lswt -mwindows
endlocal
-------------------------------------

>>>I run the batch file and get this output:
-------------------------------------
C:\Yello>setlocal

C:\Yello>set PROG=LayoutExample 

C:\Yello>set SWT_BASE_DIR=C:\Yello\Compiler\swt\win32

... 800 more lines of "undefined reference"...
C:\Yello>endlocal
-------------------------------------
I have not modified the example files. All of gcc 3.3 and SWT are
downloaded 
pre-compiled, they were not compiled by me. I can compile programs that
consist of multiple java files 
but do not use SWT, and can also compile programs that use SWT but only
consist of one class, 
but can't compile multiple files that use SWT.

I have searched gcc-help mailing list archives and google but could not
find a solution. 
Any suggestions, links to websites, or to mail archives would be
helpful.

Regards,
Adam
