Not in executable format: File format not recognized GDB

I'm tried to debug my binary file (called click) with gdb.

When I run 

gdb ./click

I have the following error

"/home/student/Desktop/./click": not in executable format: File format not recognized

The outupt of:

uname -a

is

Linux student 4.2.0-36-lowlatency #42-Ubuntu SMP PREEMPT Thu May 12 23:39:42 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

And if I run 

file click

I get this output: 

click: ERROR: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2 error reading (Invalid argument)

Any ideas?

Your file is simply corrupt.

Possibly it is truncated (did you run out of disk space when linking it?), or you transferred it over FTP from another machine in ASCII mode (use binary mode instead).
