mcrypt example not working

Question

I am working on ubuntu in c++ code. I wanted to test an exmple with mcrypt from this link: http://linux.die.net/man/3/mcrypt , but whn i do:

gcc test.c -o testt -lmcrypt 

there is no result back. why?

Where am I wrong?

For both examples the result is the same. appreciate!!

Answer 1

gcc test.c -o testt -lmcrypt

gives no result, because there is no error (see UNIX culture[1]).

Try to run the resulting binary with

./testt

to see the output (if any).

Probe the file, if you will

file ./testt
ldd ./testt
objdump -Ct ./testt

If all is well, you'll get all kinds of information about your file :)
