我正在使用CUDA8.0在jetsonTX1上使用Ubuntu 16.04，我在opencv / samples / gpu中编译opencv示例代码时遇到了麻烦。
我可以在opencv / samples / cpp中编译样本，例如
g++ -ggdb facedetect.cpp -o facedetect `pkg-config --cflags --libs opencv`
工作，但不在gpu文件夹中的示例中。
我尝试了以下命令，
g++ -ggdb `pkg-config opencv --cflags --libs` optical_flow.cpp -o optical_flow
我收到了这个错误：

如何测试此示例代码以确认我的安装？
至少，python2.7可以导入cv2和某些功能，例如＆＃39; imread＆＃39;工作正常。
然后我试了
g++ -L/usr/lib/python2.7/dist-packages/ optical_flow.cpp -o optical_flow `pkg-config --cflags --libs opencv` -lopencv_gpu
但它来了
/usr/bin/ld: cannot find -lopencv_gpu
collect2：错误：ld返回1退出状态
