MPIRライブラリをインストールしただけです。次のように、プログラムが空のコードでヘッダー ファイルを認識できることをテストしました。
#include <iostream>
#include <conio.h>
using namespace std;
#pragma warning(disable: 4800)
#include <mpirxx.h>
#pragma warning(default: 4800)
int main (int argc, char *argv[])
{
mpz_class aBigPO2;
aBigPO2 = 1073741824; //2^30
aBigPO2*=aBigPO2; //2^60
aBigPO2*=aBigPO2; //2^120
aBigPO2*=aBigPO2; //2^240
aBigPO2*=aBigPO2; //2^480
aBigPO2*=aBigPO2; //2^960
aBigPO2*=aBigPO2; //2^1920
// cout << aBigPO2 << endl;
cout<<"Hello World";
getch();
}
上記のコードをコンパイルしてデバッグしようとしたところ、問題なく動作し、Hello World ステートメントを確認できました。しかし、cout << aBigPO2 << endl;ステートメントのコメントを削除すると、デバッグ時にのみ次のエラーが発生します (コンパイル時にエラーは表示されません)。
