ubuntu14.04 + gtx980ti + Cuda 8.0---Opencv3.1.0 configuration

The head hurts with the pit.

Process:

1. Browse Web download OpenCV source Opencv3.1.0 zip

2.unzip Decompression

3. Install a stack of pre-requisite environments:

sudo apt-get install xx xx xx

sudo apt-get install build-essentialsudo apt-get install CMake git libgtk2. 0-dev pkg-config libavcodec-dev libavformat-dev libswscale-devsudo apt-get Install Python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-

During the installation of the Libgtk2.0-dev, there was a dependency problem, and finally by switching the Apt-get source server as the ' primary server ' (because our lab's network can be automatically over the wall) resolved the problem (in the software update set)

It is said to choose another site to choose Ali or 163 mirror server speed is good!

4.CD Opencv3.1.0

mkdir Build

5.cmake There was always a problem with this, and finally the command option was used:

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
cmake -D CMAKE_BUILD_TYPE=Release -DINSTALL_CREATE_DISTRIB=ON -D CMAKE_INSTALL_PREFIX=/usr/local ..

Make-j16 here is a parallel acceleration when cmake based on the number of CPU cores you have

The error that occurred:

Error: ' Nppigraphcutstate ' have not been declared

By modifying:

Vim ~/envoriment/opencv-3.1.0/modules/cudalegacy/src/graphcuts.cpp

Solve.

6.sudo make Install
