Had a hard job getting this to work. But as usual the solution is quite simple:

1. Download and unzip http://google-web-toolkit.googlecode.com/svn/tools/redist/mozilla/mozilla-1.7.13.tar.gz
2. Add $INSTALLED_MOZILLA (e.g. /code/mozilla-1.7.13) to mozilla-hosted-browser.conf in the GWT
3. Add $INSTALLED_MOZILLA (e.g. /code/mozilla-1.7.13) to /etc/ld.so.conf.d/libc.conf (can be any file in that dir ending in conf)
4. run ldconfig
5. Start your app and have fun!

If you see gwt-linux-1.5.2/libgwt-ll.so: undefined symbol: JS_PropertyStub then your mozilla-hosted-browser.conf needs to be set to the downloaded mozilla from set 1. Looks like the newer Firefox and Seamonkey dont have this symbol.

Well yeah not immediately great.

I thought I`d start small by synchronizing Tomboy with a directory. Fail. Running Conduit from the command line revealed the answer – Incompatible Tomboy version. Aha thinks me I`ll upgrade Tomboy – there is bug about the version thing logged on launchpad currently. So, download the current version 0.11 the bleeding edge development one.

Building it fails everytime complaining with: Mono.Cairo.dll missing. Now I wasn’t able to fix this on purpose. I ran

sudo apt-get build-dep tomboy

Which did the right thing fixing the strange missing but installed dll.

Back to Conduit. Now running the spanking new Tomboy I fired up the sync again.

Fail.

Same error this time. So its not Tomboy thats the issue. So as I`m planning to hack around with this anyway I checkout the latest code from subversion using the following instructions: Build Instructions. As its prebuilt from subversion you can just run it without compiling. It all works a treat now. Now for playing.

Thanks John Carr for your speech at LUG Radio for pointing this cool bit of kit out.
