并行程序编译错误

我编写了一个并行代码，我可以编译它并在 win7 下运行它，但现在我必须在 linux ubuntu 11.04 下运行它，当我编译代码时，我收到此错误：

usr/bin/ld :cannot find -lcrcollect2

:ld returned 1 退出状态

我的编译器是 mpicxx，我使用 mpich2。我的代码大约有 3000 行，但我使用以下代码进行测试

#include <iostream>
#include <mpi.h>

using namespace std;

int main(int argc, char ** argv){
    int mynode, totalnodes;
    MPI_Init(&argc,&argv);
    MPI_Comm_size(MPI_COMM_WORLD, &totalnodes);
    MPI_Comm_rank(MPI_COMM_WORLD, &mynode);
    cout << "Hello world from process " << mynode;
    cout << " of " << totalnodes << endl;
    MPI_Finalize();
}

，并使用此命令进行编译 mpicxx hello.cpp

I write a parallel code that I can compile it and run it under win7 but now I have to run it under linux ubuntu 11.04 when I compile my code I get this error:

usr/bin/ld :cannot find -lcr

collect2:ld returned 1 exit status

my compiler is mpicxx and I use mpich2.
my code has about 3000 lines but I use the following code for testing

#include <iostream>
#include <mpi.h>

using namespace std;

int main(int argc, char ** argv){
    int mynode, totalnodes;
    MPI_Init(&argc,&argv);
    MPI_Comm_size(MPI_COMM_WORLD, &totalnodes);
    MPI_Comm_rank(MPI_COMM_WORLD, &mynode);
    cout << "Hello world from process " << mynode;
    cout << " of " << totalnodes << endl;
    MPI_Finalize();
}

and I use this command for compiling it mpicxx hello.cpp
