Hi,
> g++ -lcrypto++ -o md5test md5test.cpp
It looks like the library name is incorrect. Did you change it in the
Crypto++ makefile (or is it now being named crypto++.a?) I am not a g++
expert.

Here is my test app:
#include <crypto++/md5.h>
#include <crypto++/filters.h>
#include <crypto++/files.h>
#include <crypto++/hex.h>
#include <crypto++/cryptlib.h>
#include <iostream>
using namespace CryptoPP;
using namespace std;
int main( int argc, char** argv )
{
MD5 hash;
byte buffer[2 * MD5::DIGESTSIZE]; //output size of the buffer
FileSource f(argv[1], true,
new HashFilter(hash,
new HexEncoder(new ArraySink(buffer,2 *
MD5::DIGESTSIZE))));
cout << string((const char*)buffer,2 * MD5::DIGESTSIZE) << endl;
return 0;
}
I compile it with g++ -lcrypto++ -o md5test md5test.cpp
And here are my errors:

And many many more.
Does anybody know what this means?
