RSSOwl 64bit and can't run with 32bit XULRunner?

  • Anonymous - 2013-04-06

    I tried to run RSSOwl 2.1.6 64bit on Kubuntu 12.10 64bit, and I keep getting this error: "RSSOwl was unable to create a browser for reading news. Please refer to the FAQ for further help.", So I added the parameter "-Dorg.eclipse.swt.browser.XULRunnerPath=[path to rssowl]/xulrunner/", but this doesn't fix the error. I then installed RSSOwl 2.1.6 32bit, and added a parameter to run with 32bit java, and I had no troubles. When I followed the FAQ to fix the browser issue in the 64bit version, and went to download page for XULRunner, I realized that only 32bit builds of that version are available.

    Has anyone successfully ran RSSOwl 64bit with the browser? From what I can tell, the 64bit distribution of RSSOwl is effectively useless, as I think it is compatible with 32bit XULRunner.

    The newer versions of XULRunner have 64 bit builds, but I read that RSSOwl only works with the 1.9.2.x branch. Is there any plans to use a newer version of XULRunner in the future? Also, I have Chromium 25 and Firefox 20 installed, why isn't RSSOwl using those, as stated in the FAQ?

    Did you try the RSSOwl from or from ?

    RSSOwl on Linux can only run in this configurations:
    1. RSSOwl 64Bit + Java 64Bit + XULRunner 64Bit
    2. RSSOwl 32Bit + Java 32Bit + XULRunner 32Bit
    (with XULRunner 1.9.2.xx)
    There are 64Bit builds of XULRunner 1.9.2.x available, but I don't remember where. They are bundled with the x64 ZIP files available on
    I have had both configurations up and running. For recent Linux distributions you may also need to fix a libhunspell issue, see for how to do this. The path may be incorrect. On my fedora the path is /usr/lib64/libhunspell… so make sure you get the correct path.

    Chromium's engine can't really be used since it is changing much too often and is not really suitable for use as library. More recent versions of Eclipse and SWT (which RSSOwl is based on) are able to use webkit on linux. I'm hacking a bit on this right now…
