ubuntu - 在ubuntu中用cuda编译opencv的makefile停止工作

Question

我正在尝试在我的笔记本电脑上编译一个项目，其中我需要 CUDA 和 opencv。
所以我创建了3个文件

主文件

内核.cu

内核.h

在 main.cpp 我有 opencv 代码，在 kernel.cu 我有我的内核。
我正在使用我在另一个项目中找到的这个 makefile:

CXX=g++
CUDA_INSTALL_PATH=/usr/local/cuda
CFLAGS= -I. -I$(CUDA_INSTALL_PATH)/include `pkg-config --cflags opencv`
LDFLAGS= -L$(CUDA_INSTALL_PATH)/lib64 -lcudart `pkg-config --libs opencv`

all:
    $(CXX) $(CFLAGS) -c main.cpp -o main.o
    nvcc $(CUDAFLAGS) -arch="sm_21" -c kernel.cu -o kernel.o
    $(CXX) $(LDFLAGS) main.o kernel.o -o main

我曾在另一台使用 opencv 2.4.2、CUDA 4.0 和 gcc 4.4 的计算机上尝试过相同的项目，它运行良好，但现在我在笔记本电脑上使用 opencv 2.4.2、CUDA 4.2 和 gcc 4.6 进行尝试，它不断返回错误最后一行，但它确实创建了 main.o 和 kernel.o，如果我注释掉最后一行，它不会给出错误。

我已经构建并运行了 opencv 和 cuda sdk 示例，它们分别运行良好。
你能帮助我吗？

这是它返回的内容:

Answer 1

您可以尝试将所有 -l 选项放在 kernel.o 后面吗？

此致!
