I was able to compile with the cast:
$ cat test.cxx
#include <iostream>
#include <string>
using namespace std;
#include "salsa.h"
#include "algparam.h"
#include "argnames.h"
using namespace CryptoPP;
// g++ -Wall -I . test.cxx ./libcryptopp.a -o test.exe
int main(int argc, char* argv[])
{
byte key[32], iv[8];
Salsa20::Encryption enc;
AlgorithmParameters params = MakeParameters(Name::IV(), (const byte*)iv)
(Name::Rounds(),12);
enc.SetKey(key, 32, params);
return 0;
}
$ g++ -Wall -I . test.cxx ./libcryptopp.a -o test.exe
$ ./test.exe
$
