我有一個使用MPI進行簡單程序的任務。我嘗試在開發的C++一個Hello World程序後使用mpi.h頭和編譯,該makefile.win正在出現,並以下錯誤即將(錯誤)在Dev C++上未定義對MPI的引用
D:\Assignment\Project\MPI\tesmpi.o tesmpi.cpp:(.text+0x21): undefined reference to `MPI_Init'
D:\Assignment\Project\MPI\tesmpi.o tesmpi.cpp (.text$_ZN3MPI9IntracommC2Ev[__ZN3MPI9IntracommC2Ev]+0xf): undefined reference to `MPI::Comm::Comm()'
... and other 190 errors like that
D:\Assignment\Project\MPI\[Error] id returned 1 exit status
D:\Assignment\Project\MPI\recipe for target 'Project' failed
我已經輸入庫,包括在項目選項目錄也鏈接器與msmpi.lib。呃,順便說一句,我使用微軟MPI和微軟SDK的MPI。有什麼我可以做的嗎?
這是我的計劃
#include <mpi.h>
#include <stdio.h>
int main(int argc, char** argv) {
// Initialize the MPI environment
MPI_Init(NULL, NULL);
// Get the number of processes
int world_size;
MPI_Comm_size(MPI_COMM_WORLD, &world_size);
// Get the rank of the process
int world_rank;
MPI_Comm_rank(MPI_COMM_WORLD, &world_rank);
// Get the name of the processor
char processor_name[MPI_MAX_PROCESSOR_NAME];
int name_len;
MPI_Get_processor_name(processor_name, &name_len);
// Print off a hello world message
printf("Hello world from processor %s, rank %d" " out of %d processors\n",
processor_name, world_rank, world_size);
// Finalize the MPI environment.
MPI_Finalize();
}
我像往常一樣使用dev C++編譯器編譯程序,如何在dev C++編譯器中添加'mpiC++'?或者它可以用cmd完成? – newcomers
