Well, for a start you have your compiler options messed up. If you've
already set #include "../../software/crypto" as a preprocessor directive
in your code their is no need to tell the compiler it's additional
include path. If you do that you'll end up with
../../software/crypto../../software/crypto !
You need to pass it a library directory though so it can find the
cryptopp lib.
Try changing your code to:
#include "aes.h"
#include "modes.h"
and run your compiler with:
g++ -Wall -O0 -I../../software/crypto -L../../software/crypto cr.cpp -o
cr -lcryptopp
And see if that works. When you run it, and if cryptopp is a shared
library, make sure the runtime loader can find the lib to. Ensure this
by setting LD_LIBRARY_PATH correctly (export
LD_LIBRARY_PATH=$PWD/../../software/crypto or something!).
