So you're logged into a remote machine running Centos 7, from a machine running an X server, and, on the command line on the remote machine, you run ./wireshark?
If so, then you need to make sure that the DISPLAY environment variable is set to refer to the machine with the X server; the message
I/O error (code 1) XIO: fatal IO error 2 (No such file or directory) on X server "localhost:16.0" after 363 requests (363 known processed) with 0 events remaining.
means that it's trying to connect to "localhost" - i.e., it's trying to connect to an X server running on the remote machine.
But still I suggest better diagnostic when GUI starting
Please send your suggestion to the developers of the X11 client library - we don't print that message, the X11 client library does. Wireshark calls Qt routines to display the GUI, and versions of Qt that use X11 as the window system call the X11 client library to do display operations.
