[omniORB] omniorb 2.8 and 3.01

[Sai-Lai Lo]

Just to give you an example. On our machines, we have all the shared
libraries of all omniORB versions living in one directory, e.g.
/project/omni/version6.0/lib/sun4_sosV_5.5.

$ export LD_LIBRARY_PATH=/project/omni/version6.0/lib/sun4_sosV_5.5

$ ldd omniORB_300/bin/eg2_clt
        libomniORB3.so.0 =>      /project/omni/version6.0/lib/sun4_sosV_5.5/libomniORB3.so.0
        libtcpwrapGK.so.2 =>     /project/omni/version6.0/lib/sun4_sosV_5.5/libtcpwrapGK.so.2
        libomnithread.so.2 =>    /project/omni/version6.0/lib/sun4_sosV_5.5/libomnithread.so.2
        libpthread.so.1 =>       /usr/lib/libpthread.so.1
        libposix4.so.1 =>        /usr/lib/libposix4.so.1
        libsocket.so.1 =>        /usr/lib/libsocket.so.1
        libnsl.so.1 =>   /usr/lib/libnsl.so.1
        libm.so.1 =>     /opt/SUNWspro/lib/libm.so.1
        libC.so.5 =>     /usr/lib/libC.so.5
        libw.so.1 =>     /usr/lib/libw.so.1
        libthread.so.1 =>        /usr/lib/libthread.so.1
        libc.so.1 =>     /usr/lib/libc.so.1
        libdl.so.1 =>    /usr/lib/libdl.so.1
        libintl.so.1 =>  /usr/lib/libintl.so.1
        libmp.so.1 =>    /usr/lib/libmp.so.1

$ ldd omniORB_280/bin/eg2_clt
        libomniORB2.so.8 =>      /project/omni/version6.0/lib/sun4_sosV_5.5/libomniORB2.so.8
        libomniDynamic2.so.8 =>  /project/omni/version6.0/lib/sun4_sosV_5.5/libomniDynamic2.so.8
        libomnithread.so.2 =>    /project/omni/version6.0/lib/sun4_sosV_5.5/libomnithread.so.2
        libpthread.so.1 =>       /usr/lib/libpthread.so.1
        libposix4.so.1 =>        /usr/lib/libposix4.so.1
        libsocket.so.1 =>        /usr/lib/libsocket.so.1
        libnsl.so.1 =>   /usr/lib/libnsl.so.1
        libtcpwrapGK.so.1 =>     /project/omni/version6.0/lib/sun4_sosV_5.5/libtcpwrapGK.so.1
        libm.so.1 =>     /opt/SUNWspro/lib/libm.so.1
        libC.so.5 =>     /usr/lib/libC.so.5
        libw.so.1 =>     /usr/lib/libw.so.1
        libthread.so.1 =>        /usr/lib/libthread.so.1
        libc.so.1 =>     /usr/lib/libc.so.1
        libdl.so.1 =>    /usr/lib/libdl.so.1
        libintl.so.1 =>  /usr/lib/libintl.so.1
        libmp.so.1 =>    /usr/lib/libmp.so.1

As you can see, the loader is able to pick the right shared library
version. This is taken from Solaris 2.5 but the applies all platforms.
