    Missing shared library file for equinox lancher

    A few days ago, I upgraded to Ubuntu 11.10. Now I am having problems with my Eclipse programming application. When I try to run the app, I get the following error message:
    "The Eclipse executable launcher was unable to locate its
    companion shared library."

    I then ran Eclipse at the command line for a more detailed explanation and got this message:
    "plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.0. 200.v20090519: cannot open shared object file: No such file or directory"

    I looked for this file inside the plugins directory and discovered that the file does not exist. I reviewed the eclipse.ini and saw that the file is referenced there:
    ---------------------------------------------------------------------------------------------
    -startup
    plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v2009071 5.jar
    --launcher.library
    plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.0. 200.v20090519
    -showsplash
    org.eclipse.platform
    --launcher.XXMaxPermSize
    256m
    -vmargs
    -Xms128m
    -Xmx512m
    -Dorg.eclipse.equinox.p2.reconciler.dropins.directo ry=/usr/share/eclipse/dropins
    ---------------------------------------------------------------------------------------------

    I am using Eclipse version 3.7. How can I fix this problem? Do I need change the referenced file to a different name or do I need to somehow download this launcher from the Eclipse website?

    Also, I did a command line search (find / -name 'org.eclipse.equinox.launcher.*' 2>/dev/null) for a launcher and found these files:

    /usr/lib/eclipse/dropins/sdk/plugins/org.eclipse.equinox.launcher.source_1.2.0.dist.jar
    /usr/lib/eclipse/plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1. 100.dist


    So, I have no idea how I am suppose to fix this. Your help is greatly appreciated.

    The startup and launcher.library should be changed to the following in the ini file and you will be fine

    Code:
    -startup
    plugins/org.eclipse.equinox.launcher_1.2.0.dist.jar
    --launcher.library
    plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.100.dist

    an update to this answer:
    i had the same problem upgrading to the next version. the correct filenames for me were:

    -startup
    plugins/org.eclipse.equinox.launcher_1.3.0.dist.jar
    --launcher.library
    plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1. 200.dist

    it's a bit of a trick because the error message in the terminal is "plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1. 100.dist: cannot open shared object file: No such file or directory", but just changing that directory name doesn't fix it - the launcher doesn't exit either.
