hi everybody
I have Eclipse 3.0, gcj & gcc 3.4 on windows 2K.
I tried to compile my swt class with gcj and works, but I can't manage to
link the file so I have not an exe at the end of the compilation. I have
<classname>.o, obviously.
the fact is that I need a swt.lib file to get the linking, I suppose, but
I can't find the way to get it.
I tried to compile the swt.jar from the prompt but had no success.
any idea??

I've never used gcj, but I'll take a guess about the problem. Since SWT
has native code, you will need to link your executable with the library
that contains the native code. This is usually done by passing a .lib
file to the compiler. This file can be generated when the swt dll is
built (swt-win32-XXXX.dll). However, it is probably not distributed by
the SWT team, because normal users have no use for it.
That being said, I think you will have to try to rebuild the swt dll
yourself. The build might already generate a .lib for you. If not, you
will have to modify the linker options yourself to generate it.

After poking around the gcj site a bit, I think my comment may have been
incorrect. It looks like you can place the JNI library on the command
line for linking. You were probably asking about how to compile all of
the SWT java files. Can't help you there.
Sorry for any confusion :)

Program consists only of an EXE-File and a single DLL?!?
Nice day.

What I need - just EXE-file, without even this single DLL.
When user clicks on application via Intranet, I can not pass two
files, only one (EXE).
I know about GCJ can use it to create EXE, but it still requires SWT DLL.

Yes thats right. You need this second file. I hope you can find the
solution for your problem.
I have an other prolem: I also work with gcj and I can make an EXE file
but my aplication needs a connection to a database so i search for the
database-driver dynamically like "Class.forName(klass).newInstance();" and
in eclipse it works fine but when I make the EXE file I cannot insolve the
driver jar so I cannot make a connection?!? Do you have an idea, if yes
could you post the source code. THANKS!!

Konstantin,
Have you considered using Java Web Start to deploy your application over the
internet?

Yes, but my users don't have Java installed.
In reality this application has goal to install other applications on
user's computer. Not only Java, it will install/update any application
on our enterprise.

You can try to have direct import of this class, i.e.
import com.provider.DriverClass;
