I have followed the instructions from the Wiki for building SWT from CVS and followed mostly the FAQ, and yet I get the exception when below I try to run Eclipse, a snippet, or an SWT example.
Here is what I did:
(in a workspace having platform-ui and p2 checked out)
1) check out oe.swt, swt.x86_64, swt.examples
2) Copy the classpath per instructions in swt
3) Execute the build.jars target in the build.xml in the swt.x86_64 plugin
4) Refresh that plugin, clean build
I also tried to change the this line in the .classpath file:
<attribute name="org.eclipse.jdt.launching.CLASSPATH_ATTR_LIBRARY_PATH_ENTRY " value="org.eclipse.swt.gtk.linux.x86_64"/>
(adding the _64), both ways produce the same result.
I tried to delete the swt.jar file from the x86_64 plugin and it still gets the same error, so it looks like it's getting a 32 bit swt.jar from somewhere, but I can't figure out where.
I'm running on Unbuntu x86_64 machine with an X86_64 version of Eclipse (Build id: I20100225-1936)
I'm sure I'm doing something stupid, but can't figure it out. Also the FAQ for the gtk.x86_64 seems a little out of date when it talks about the build.xml file (the specified targets in the FAW don't exist).

Hi Francis,
Yes the FAQ does look out of date, it should be updated. The following
steps worked for me:
- retrieve the projects from CVS
- rename .classpath_gtk to .classpath
- execute the jar.plugin target in the build.xml in the swt.x86_64 plugin
(FAQ: http://www.eclipse.org/swt/faq.php#howbuildplugin )
If this doesn't work for you then please follow up.
