c++ - cuda单独编译模式和cudart静态链接的链接错误
问题描述
基本上，我的目标如下：我想使用 CUDA SDK Toolkit 创建一个程序，并且我想在安装了 NVIDIA GPU 和 NVIDIA 驱动程序但不需要 CUDA Toolkit 的系统上运行该程序。我的想法是静态链接 cuda 库。好吧，即使是一个简单的案例，我也没能做到。让我给你看。我有三个文件：main.cpp、kernel.cu 和 header.h。这些文件的内容如下。
主文件
#include <stdio.h>
#include "header.h"
int main()
{
const int arraySize = 5;
const int a[arraySize] = { 1, 2, 3, 4, 5 };
const int b[arraySize] = { 10, 20, 30, 40, 50 };
int c[arraySize] = { 0 };
// Add vectors in parallel.
addWithCuda(c, a, b, arraySize);
printf("{1,2,3,4,5} + {10,20,30,40,50} = {%d,%d,%d,%d,%d}\n",
c[0], c[1], c[2], c[3], c[4]);
return 0;
}
头文件.h
#pragma once
void addWithCuda(int *c, const int *a, const int *b, unsigned int size);
内核.cu
#include "header.h"
#include "cuda_runtime.h"
#include "device_launch_parameters.h"
#include <stdio.h>
__global__ void addKernel(int *c, const int *a, const int *b)
{
int i = threadIdx.x;
c[i] = a[i] + b[i];
}
void addWithCuda(int *c, const int *a, const int *b, unsigned int size)
{
int *dev_a = 0;
int *dev_b = 0;
int *dev_c = 0;
cudaError_t cudaStatus;
// Choose which GPU to run on, change this on a multi-GPU system.
cudaStatus = cudaSetDevice(0);
if (cudaStatus != cudaSuccess) {
fprintf(stderr, "cudaSetDevice failed! Do you have a CUDA-capable GPU installed?");
goto Error;
}
// Allocate GPU buffers for three vectors (two input, one output) .
cudaStatus = cudaMalloc((void**)&dev_c, size * sizeof(int));
if (cudaStatus != cudaSuccess) {
fprintf(stderr, "cudaMalloc failed!");
goto Error;
}
cudaStatus = cudaMalloc((void**)&dev_a, size * sizeof(int));
if (cudaStatus != cudaSuccess) {
fprintf(stderr, "cudaMalloc failed!");
goto Error;
}
cudaStatus = cudaMalloc((void**)&dev_b, size * sizeof(int));
if (cudaStatus != cudaSuccess) {
fprintf(stderr, "cudaMalloc failed!");
goto Error;
}
// Copy input vectors from host memory to GPU buffers.
cudaStatus = cudaMemcpy(dev_a, a, size * sizeof(int), cudaMemcpyHostToDevice);
if (cudaStatus != cudaSuccess) {
fprintf(stderr, "cudaMemcpy failed!");
goto Error;
}
cudaStatus = cudaMemcpy(dev_b, b, size * sizeof(int), cudaMemcpyHostToDevice);
if (cudaStatus != cudaSuccess) {
fprintf(stderr, "cudaMemcpy failed!");
goto Error;
}
// Launch a kernel on the GPU with one thread for each element.
addKernel<<<1, size>>>(dev_c, dev_a, dev_b);
// Check for any errors launching the kernel
cudaStatus = cudaGetLastError();
if (cudaStatus != cudaSuccess) {
fprintf(stderr, "addKernel launch failed: %s\n", cudaGetErrorString(cudaStatus));
goto Error;
}
// cudaDeviceSynchronize waits for the kernel to finish, and returns
// any errors encountered during the launch.
cudaStatus = cudaDeviceSynchronize();
if (cudaStatus != cudaSuccess) {
fprintf(stderr, "cudaDeviceSynchronize returned error code %d after launching addKernel!\n", cudaStatus);
goto Error;
}
// Copy output vector from GPU buffer to host memory.
cudaStatus = cudaMemcpy(c, dev_c, size * sizeof(int), cudaMemcpyDeviceToHost);
if (cudaStatus != cudaSuccess) {
fprintf(stderr, "cudaMemcpy failed!");
goto Error;
}
Error:
cudaFree(dev_c);
cudaFree(dev_a);
cudaFree(dev_b);
}
虽然我并不认为代码的上下文很重要，但我还是决定展示它。
然后我有两个文件：run 和 run_static。
跑
g++ -c main.cpp;
nvcc -c kernel.cu;
g++ main.o kernel.o -o test -L/usr/local/cuda-10.2/lib64 -lcudart -lcudadevrt
run_static
g++ -c main.cpp;
nvcc -c kernel.cu;
g++ main.o kernel.o -o test_static -L/usr/local/cuda-10.2/lib64 -lcudart_static -lcudadevrt
我可以使用make但我决定简化一切。
好吧，./run创建测试可执行文件，它反过来产生正确的输出。这是动态链接的情况。但是，./run_static不会创建test_static。相反，它会引发错误：

显然，我缺少一些简单的东西。
更新。我试过了
g++ -c main.cpp;
nvcc -c kernel.cu;
g++ main.o kernel.o -o test -L/usr/local/cuda-10.2/lib64 -static -lcudadevrt -ldl -pthread -lrt -lcudart_static
和
g++ -c main.cpp;
nvcc -c kernel.cu;
g++ main.o kernel.o -o test -L/usr/local/cuda-10.2/lib64 -static -lcudart_static -lcudadevrt -ldl -lrt -pthread
在这两种情况下，我都收到以下错误：
/usr/bin/ld: cannot find -lrt
/usr/bin/ld: cannot find -lstdc++
/usr/bin/ld: cannot find -lm
/usr/bin/ld: cannot find -lpthread
/usr/bin/ld: cannot find -lc
collect2: error: ld returned 1 exit status
更新 2。
什么对我有用
-lcudadevrt -lcudart_static -lrt -pthread -ldl -lc -lpthread -Bstatic -lgcc -lstdc++ -ldf
您需要将其与 -L$(YOUR_PATH_TO_gclib)
解决方案
您缺少和libdl，将以下内容添加到您的链接行：libpthreadlibrt
-ldl -pthread -lrt
它们是在 cuda 共享对象文件上libcudart运行的依赖项，以检查其他人。ldd
根据 OP 评论编辑。
另外，请注意，使用 GCC 链接器，-Wl,--start-group -lmylib -lmyotherlib -Wl,--end-group如果您不知道顺序依赖关系（什么取决于什么），则需要使用： 包装库依赖项。
