When I remove "-std=c++11" from CXX_FLAGS, I do not get the above error, but I am stuck with the following error:

VI_MEAN_ws/src/VI-MEAN/stereo_mapper/src/tic_toc.h:22:20: error: 'std::chrono' has not been declared
end = std::chrono::system_clock::now();
VI_MEAN_ws/src/VI-MEAN/stereo_mapper/src/tic_toc.h:23:14: error: 'std::chrono' has not been declared
std::chrono::duration elapsed_seconds = end - start;
VI_MEAN_ws/src/VI-MEAN/stereo_mapper/src/stereo_mapper_node.cpp:80:19: error: 'id' does not name a type
for (auto id : id_set_r)
etc.

Henceforth, it can be concluded that the code base depends heavily on c11 features. Therefore, I am back to the original problem.

I catch the problem the same as yours,how did you solve it?

@arnabsinha @tiantiandabaojian I catch the problem the same as yours,how did you solve it?

[xiaobainixi]

@cumtchenchang 没用这个，没调通，自己重写了一个

[cumtchenchang]

@重写的stereo_mapper吗？能方便加微信或者qq沟通吗？

[xiaobainixi]

@cumtchenchang 没重写这个，太复杂了 就重写了一个双目求视差并制作三维图的小程序

[cumtchenchang]

@tiantiandabaojian 抱歉这么晚还来打扰你，我根据你的思路调试一直出问题，请问能够分享下你的代码吗？或者私下沟通.

[xiaobainixi]

@cumtchenchang 代码写的很乱，就用的OPENCV的SGBM做的，代码的话去我GITHUB上吧

just remove -std=c++11 in the CUDA_NVCC_FLAGS. it conflicts with the prior setting in CMAKE_CXX_FLAGS
