[news.eclipse.platform.swt] Re: SWT installallation on linux64

["Grant Gayed" <grant_gayed@xxxxxxxxxx>]

swt has a constant in its java implementation that indicates which library
version to look for, so if it's looking for swt-gtk-3347 then you're running
with the swt's java code from this version.

Running on linux shouldn't be any different than running on windows.  There
should be two swt plugin jars, one called
org.eclipse.swt_<eclipseVersion>.<swtVersion> which contains very little,
and the other called
org.eclipse.swt.<ws>.<os>.<arch>_<eclipseVersion>.<swtVersion> which
contains the platform-specific implementation.  If the swt versions on these
plugins indicate 3349 but at runtime it's looking for 3347 then you must be
running with an swt from somewhere else.  Check the Java Build Path for one
of your projects that depends on swt to see the location of the swt that
it's referencing.

If you're running your app as stand-alone (not as an eclipse plug-in) then
you can just put the swt platform-specific jar on your project's Java Build
Path and it should extract its matching libraries automatically at runtime.
