Hello people,
I am trying to install and use CryptoPP library in my Macbook Air M1. I did
all the make, install step. When I tried to execute a sample program, I get
an error as Undefined symbols for architecture arm64: I give the details
below.
LCG.cpp
// sample.cpp : Defines the entry point for the console application.
//
#include "StdAfx.h"
// Runtime Library Includes
#include
#include
#include
// Crypto++ Include
#include // PRNG
int main(int argc, char* argv[])
{
// Scratch Area
// Use as seed to the LCG
const unsigned int BLOCKSIZE = 16 * 8;
byte pcbScratch[ BLOCKSIZE ];
std::cout << "Seed:" << BLOCKSIZE << std::endl << std::endl;
// 1st LCG
CryptoPP::LC_RNG lcg1( BLOCKSIZE /*32 bit word */);
lcg1.GenerateBlock( pcbScratch, BLOCKSIZE );
// Output
std::cout << "The 1st LCG produced:" << std::endl;
for( unsigned int i = 0; i < BLOCKSIZE; i++ )
{
std::cout << "0x" << std::setbase(16) << std::setw(2) << std::setfill('0');
std::cout << static_cast( pcbScratch[ i ] ) << " ";
}
std::cout << std::endl;
// @nd LCG
CryptoPP::LC_RNG lcg2( BLOCKSIZE /*32 bit word */);
lcg2.GenerateBlock( pcbScratch, BLOCKSIZE );
// Output
std::cout << "The 2nd LCG produced:" << std::endl;
for( unsigned int i = 0; i < BLOCKSIZE; i++ )
{
std::cout << "0x" << std::setbase(16) << std::setw(2) << std::setfill('0');
std::cout << static_cast( pcbScratch[ i ] ) << " ";
}
std::cout << std::endl;
return 0;
}
g++ LCG.cpp
LCG.cpp:20:5: error: unknown type name 'byte'; did you mean
'CryptoPP::byte'?
byte pcbScratch[ BLOCKSIZE ];
^~~~
CryptoPP::byte

when I add CryptoPP::byte, i get,
g++ LCG.cpp
