to be fair, i am confused.

1. root at vizwall -> indicates that you are running as root
   you should try things always as USER

2. "X connection to :0.0 broken" should appear when the connection
   to the server (== your display) is gone. this happens when you
   have a remote login (do you ?) but :0.0 shows that is the local
   box and from the other mail i see that xclock is working ....

wild guess ...
could you please check with "ldd ./hellox" is there something missing ?

my output looks like these:
 ldd ./hellox
        linux-vdso.so.1 =>  (0x00007fffff1ff000)
        libX11.so.6 => /usr/lib64/libX11.so.6 (0x00007f01e385e000)
        libc.so.6 => /lib64/libc.so.6 (0x00007f01e3505000)
        libxcb-xlib.so.0 => /usr/lib64/libxcb-xlib.so.0 (0x00007f01e3303000)
        libxcb.so.1 => /usr/lib64/libxcb.so.1 (0x00007f01e30e7000)
        libXau.so.6 => /usr/lib64/libXau.so.6 (0x00007f01e2ee3000)
        libdl.so.2 => /lib64/libdl.so.2 (0x00007f01e2cdf000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f01e3b9b000)
