Could not load SWT library FC17 and Eclipse 4.2.0

[darktemplaaa]

Hi at all,

somehow there's no swt library in my home folder in /home/timo/.swt/lib/linux/x86_64/. Anyone else has the same problem? Just do a simple "HelloWorld" Test with SWT import like:

import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;


public class HelloWorldSWT {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub

Display display = new Display();
Shell shell = new Shell(display);
shell.setText("Hello world!");
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
display.dispose();

}

}


It gives you following output:

Exception in thread "main" java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:

So why are the libraries not in ~/.swt????

Why do you expect it to be there? In order for me to compile successfully the HelloWorldSWT class in Eclipse 4.2.0, first I have to add the SWT library into the project's java build path. After that the program runs fine on my F17 x86_64 system. In my 64-bit system, the SWT library is found in "/usr/lib64/eclipse/" folder. I believe they are there because of "eclipse-swt" package. Alternatively, use the SWT standalone download as recommended here.

To run the Java class outside of Eclipse IDE, I use this command.

CLASSPATH=/usr/lib64/eclipse/swt.jar:. java HelloWorldSWT

Thank you! Yeah I forgot to add the path in the "Native library location" in the Projects tab under org.eclipse.swt.gtk.linux.x86_64 which is /usr/lib64/eclipse.
