Question

我使用opencv 2.4.8和libnonfree-dev中的非空闲库。这是我的make VERBOSE = 1输出：

/usr/bin/c++ -DEIGEN_USE_NEW_STDVECTOR -DEIGEN_YES_I_KNOW_SPARSE_MODULE_IS_NOT_STABLE_YET -DFLANN_STATIC -DROSCONSOLE_BACKEND_LOG4CXX -DROS_BUILD_SHARED_LIBS=1 -DROS_PACKAGE_NAME=\"test_code\" -Dqh_QHpointer -Wno-deprecated -g -I/opt/ros/indigo/include -I/usr/include/opencv -I/usr/include/opencv2/nonfree -I/usr/include/vtk-5.8 -I/usr/include/pcl-1.7 -I/usr/include/eigen3 -I/usr/include/ni    -Wall -o CMakeFiles/test_code.dir/src/main.cpp.o -c /home/amai/working_workspace/src/test-code/src/main.cpp

当我加入时，我收到此错误：

我尝试过使用命名空间std;在指定包含类似this解决方案之前，但它没有帮助。我已经安装了非自由库并确保它们像许多解决方案所描述的那样被链接，但到目前为止，唯一消除了与向量相关的错误的是放置这些行：

#include <vector>
using namespace std;

直接进入包含文件。但是，这不会消除其他包含问题。

此问题是由安装没有CUDA支持的OpenCV库引起的。要解决此问题，请使用CUDA从源代码编译OpenCV。

使用OpenCV非自由库时，矢量未定义
