Hey Taha,

It sounds like the problem is that, while GWT comes with a 32-bit
version of SWT, you're using a 64-bit JVM. If you switch to a 32-bit
JVM, then you'll be set! (and in future versions of GWT, once we have
the OOPHM feature, it won't be an issue)

We should probably document this better for GWT.

Hope this helps!

Hi!

I have the same problem (as anyone with modern system) and 32bit JVM
(with dependencies) is not enough.
You need (names for openSUSE):
- gtk2-32bit
- libgthread-2_0-0-32bit


Try to install libgtk2-32bit.

When 64bit GWT will be available (because having 32bit JVM with 20+
dependencies installed isn't pretty)?

Probably I'm missing something or doing something wrong but trunk
(with OOPHM) doesn't work either (at least OOB). How can I use OOPHM
instead of hosted mode?

Yes, it should be stated on the download page that it doesn't work
with 64bit JVM.

Thanks.

forgot to add, mozilla 1.7 also requires libstdc++33-32bit

OK, so I've solved it, I've looked around and found this page:
http://code.google.com/p/google-web-toolkit/wiki/UsingOOPHM

Now OOPHM works :D

Thanks
