Hi,
I'm currently working on an application which use SWT.
I've tried to switch from eclipse 3.1M5 to eclipse 3.1M6. My project uses
the eclipse's libraries:
* org.eclipse.core.runtime_3.1.0.jar
* org.eclipse.jface_3.1.0.jar
* org.eclipse.swt_3.1.0.jar
* org.eclipse.ui.forms_3.1.0.jar
When I launch it through the context menu entry "Run as SWT application",
I get the following error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no swt-pi-gtk-3128 in java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1517)
at java.lang.Runtime.loadLibrary0(Runtime.java:788)
at java.lang.System.loadLibrary(System.java:834)
at org.eclipse.swt.internal.Library.loadLibrary(Library.java:12 3)
at org.eclipse.swt.internal.gtk.OS.<clinit>(OS.java:19)
at org.eclipse.swt.internal.Converter.wcsToMbcs(Converter.java: 63)
at org.eclipse.swt.internal.Converter.wcsToMbcs(Converter.java: 54)
at org.eclipse.swt.widgets.Display.<clinit>(Display.java:122)
at com.mcafee.scmlov.App.main(App.java:57)
I have exactly the same problem when I run my application from the
command line.
In M5, there was an "external" shared library libswt-pi-gtk-3123.so but
in M6 this library has moved inside the swt jar.
Does someone know what is the right way for launching an SWT application
with M6.
Thanks in advance

No, I didn't as I'm currently developping on Linux.
The flag -Djava.library.path=path_to_my_swt_dlls_directory should avoid me
to have to put anything in the winnt/system32 directory.
In order to be sure I test my application on Windows and it works!
So the problem seems to be specific to linux/gtk2:
If I run from the command line: "java
-Djava.library.path=path_to_my_swt_dlls_directorypath_to_my_ swt_directory
-classpath=xxx myprogram.java", it works fine
But if I run it from eclipse with the option
-Djava.library.path=path_to_my_swt_dlls_directory, it doesn't work

Are you running it as a Java app and not a SWT App? The SWT app is broken.

Thanks, I've created a brand-new launch entry with the right command
line arguments and it works now!
Thanks
