Not in executable format: File format not recognized GDB

Question

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?

Could you please share the command you are using to compile your program? — Christopher Crowe

I compile the program with eclipse and I tried to run the binary file in another computer. — Elisabetta

What does uname -a output on the computer where you compile the program? — CristiFati

On the computer where gdb gives you that error, what happens if, outside of gdb, you try to run ./click ? — Mark Plotnick

@CristiFati the output of uname -a in the computer where I compile the program is: Linux elisabetta-XPS-13-9343 4.2.0-36-generic #42-Ubuntu SMP Thu May 12 22:05:35 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux — Elisabetta

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).
