使用OpenCV非自由库时矢量未定义

Question

我正在使用libnonfree-dev的非自由库的opencv 2.4.8。下面是我的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

当我包含时，我得到这个错误:

我试过使用命名空间std;在此之前，包括像这个解决方案指定，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起来，但到目前为止，唯一已经消除了向量相关错误的是放入以下行:

#include <vector>
using namespace std;

直接放入include文件中。但是，这并不能消除其他include问题。

此问题是由于安装没有CUDA支持的OpenCV库导致的。要解决这个问题，使用CUDA从源代码编译OpenCV。
