    Problem with custom shared library

    Hi,
    I created a shared Library called libTree.so to be used with a program called Insert.
    When doing it in a Mandrake 10 machine (2.6.3-7mkd, i686) , everything works fine
    The problem occured when i copy all the files to a Fedora Core 4 machine (2.6.11-1.1369_FC4.stk16, i686) and try to run it. The error is:

    Code:
    error while loading shared libraries: libTree.so: cannot open shared object file: No such file or directory
    Have tried to add the path to LD_LIBRARY_PATH and even copy the libTree.so to /usr/local/bin; but no help.

    Does anyone know why it is ?

    Thanks in advance.
    Cheers.

    Are you running ldconfig as root after copying the library over (to some place in LD_LIBRARY_PATH)?
    If you understand what you're doing, you're not learning anything.

    You'd know whether or not you ran it or not, by whether or not you ran it or not. It sounds like you didn't.
