Hello World: Error

[Jerrold Clint Balansi]

Thanks for your reply..

Here's what I got

[root at vizwall jcX Files]# ldd ./HelloX
        libX11.so.6 => /usr/lib64/libX11.so.6 (0x00000033efe00000)
        libc.so.6 => /lib64/libc.so.6 (0x00000033eda00000)
        libXau.so.6 => /usr/lib64/libXau.so.6 (0x00000033f0600000)
        libXdmcp.so.6 => /usr/lib64/libXdmcp.so.6 (0x00000033f0200000)
        libdl.so.2 => /lib64/libdl.so.2 (0x00000033ee200000)
        /lib64/ld-linux-x86-64.so.2 (0x00000033ed600000)
[root at vizwall jcX Files]#


As non-root user.. this is the output.

bash-3.2$ ./HelloX
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

./HelloX: couldn't connect to X server (null)
bash-3.2$
