Hi,

I think the gnu compiler 4.8 does not fully support c++11. Please try to use gnu 4.9.2 or higher. For reference: I am using version 5.4.0 on my tx2.

Please let me know if this solves the issue. Thanks!

Best,
Marko

I have install gcc and g++ version 7.1.0, but I don't know what is gnu.

Check out this: https://gcc.gnu.org/

Updating gcc is exactly what I meant. Is it still not working?

[Kn15263ss]

Yes! It is still not working

I had the same problem and i'm still using gcc 4.8. you can fix it by adding --std=c++11 to NVCC_FLAG in the CMakeLists.txt. i created a pull request about this problem

I think this has to do with the darknet architecture supports. I think the original darknet had commented out the line -gencode arch=compute_20,code=[sm_20,sm_21] of the darknet_ros/darknet_ros/CMakeLists.txt try it without that line
