When i make the project, there's some error, as follow:

Linking CXX executable stereo_test
../../src/libsgm.so: undefined reference to nppiFilterMedianGetBufferSize_16u_C1R' ../../src/libsgm.so: undefined reference to nppiFilterMedian_16u_C1R'
collect2: error: ld returned 1 exit status

My environment is ubuntu 16.04, cuda 9.1, thank you!

Hi.
I'm sorry for missing description about CMake version.
CMake version 3.10 supports NPP of CUDA9.x. So, try with CMake 3.10 or later.
(I could build with CMake 3.10.3)

Hi, thank you for your reply!
It works when i try with cmake 3.11, The stereo_movie runs very well, but when i enable the zed demo and make , errors occurs as follow:

I have already installed the ZED sdk downloaded from web "https://www.stereolabs.com/".Looking forward to your reply, thank you!

I'm sorry for replying late.
ZED SDK was updated, but we haven't change the demo yet.
There is a PR(#12) about upgrading demo for ZED SDK 2.0. This may help you.
