请教，不知道是什么编译错误
--------------------Configuration: gotogoto - Win32 Debug--------------------Cannot start tool.
操作成功完成。
Cannot start tool.
Error spawning 'vcspawn.exe'. The build could not be performed.
gotogoto.exe - 1 error(s), 0 warning(s)
我想知道这个是什么错误呢？？
下面是我的程序：
#include<iostream>
using namespace std;
main()
{
int m,n,i,a,b,x;
while(cin>>n)
{
if(n==0) break;
else
{
if(n%4!=0) m=int(n/4+1);
else m=n/4;
x=m*4-n;
i=1;
a=1;
b=n;
cout<<"Printing order for "<<n<<" pages:"<<endl;
while(i<=m)
{
if(x==0)
{
cout<<"Sheet "<<i<<", front: "<<b--<<", "<<a++<<endl;
cout<<"Sheet "<<i++<<", back : "<<a++<<", "<<b--<<endl;
}
else
{
cout<<"Sheet "<<i<<", front: "<<"Blank"<<", "<<a++<<endl;
cout<<"Sheet "<<i++<<", back : "<<a++<<", "<<"Blank"<<endl;
x--;
}
}
}
}
return 0;
}
