Re: [Wrapper-user] problem loading libwrapper.so

[Leif M. <le...@ta...>]

Xavier,
    That shouldn't be necessary.  The WrapperManager class will attempt 
to load
the libwrapper.so file using two names.  The first is the platform 
specific name,
in your case, libwrapper-linux-x86-32.so.  The second is the default 
libwrapper.so.
If the platform specific named file does not exist, it will fall back to 
the default name.
    This was done to make the delta-pack release possible.

    If you look at the debug output, you will see an error about the 
platform
named file not being found.  But the second libwrapper.so file should work
fine.  I can't imaging why on its won, adding the symbolic link would help
as it would still be attempting to load the original libwrapper.so file.

    What does that section of the debug wrapper.log file look like without
that symbolic link.  libwrapper-linux-x86-32.so should be failing to load.
But it should then continue on to attempt to load the libwrapper.so file.

    Cheers,
    Leif
