Question

我正在尝试在Eclipse中编译一个简单的CUDA程序。

g++ -L/opt/cuda/lib64 -o "cuda_esn" ./cu_cuda_test.o ./main.o -lcuda -lstdc++

如您所见，我正在关联-lcuda并设置库路径-L/opt/cuda/lib64。但不幸的是，我不知道为什么这不是编译。

完成输出：

make: *** [cuda_esn] Error 1

这将是源代码（尚未真正令人兴奋）：

cuda_test.h

#ifndef CUDARR
#define CUDARR

#ifdef __cplusplus
  extern "C"
#endif

void foo_wrapper();

#endif

cuda_test.cu

#include "cuda_test.h"
#include "cuda.h"
#include "cuda_runtime.h"

extern "C" void foo_wrapper()
{
}

Main.cpp的

#include <iostream>
#include "cuda_test.h"

int main() {

  std::cout << "hello world" << std::endl;

  foo_wrapper();

  return 0;
}

有人能帮助我吗？

您还需要链接到cudart，cuda运行时。添加-lcudart

CUDA 6.0链接错误：未定义引用`__cudaUnregisterFatBinary'
