In case you encounter an error like the following:
symbol lookup error: <path-to-xulrunner>/libxul.so: undefined symbol: gdk_screen_get_resolution
you should check that the version of xulrunner installed in <path-to-xulrunner> is 1.8.x. Xulrunner is a library developed by Mozilla and used by the Eclipse platform to display web content. Unfortunately, the 1.9.x versions are known to have problems integrating with SWT.
After installing xulrunner-1.8.x, there are two ways to tell eclipse where to find it:
1. In the console where you launch eclipse:
2. Add the following line:
in the "dvt_eclipse_directory/eclipse/eclipse.ini" file after "-vmargs" line
where <NEW-XULRunner-directory-path> denotes the location of the newly installed xulrunner.
