Linux(Ubuntu20.04) complie opencv with Qt, OpenGL, VTK，cuda

一、前言

先下载安装好Qt和vtk，默认已经安装好了cmake，g++，build-essential。
VTK的安装对cmake，qt都有版本要求，要注意一下。
cmake版本

cmake --version		//3.16.3

后面make之前查看下cpu核数

nproc  // 4
make -j4  // 这样应该会快一些

g++版本

g++ --version    //9.3.0

二、Qt下载安装

参考link
下载的版本也是5.9.0
清华镜像link
另外一个镜像link
定位到安装包文件夹，更改安装包权限，运行安装包

chmod +x  qt-opensource-linux-x64-5.9.0.run
./ qt-opensource-linux-x64-5.9.0.run	   //安装Qt

填写注册信息，安装组件没有选择sources，暂时没有影响。
通用字体配置库（不知道有啥用）

sudo apt-get install libfontconfig1

安装qtchooser并配置（也不知道有啥用）

sudo apt-get install qtchooser
qtchooser -install qt5.9.0 /home/根据自己路径填写/Qt5.9.0/5.9/gcc_64/bin/qmake
export QT_SELECT=qt5.9.0
qtchooser -l

安装OpenGL

sudo apt-get install mesa-common-dev
sudo apt-get install libglu1-mesa-dev -y

编译器配置不知道暂时有没有用，先参考链接配置吧

三、安装VTK

参考链接link
下载source，使用git下载的版本是9.1。

git clone --recursive https://gitlab.kitware.com/vtk/vtk.git

也是下载OpenGL，算是对上面的补充吧

sudo apt install mesa-common-dev mesa-utils freeglut3-dev ninja-build
// ninja is a speedy replacement for make, highly recommended.

官网用的是ccmake，直接在terminal中输入ccmake，可看到安装方式。
Build

mkdir -p vtk/build
cd vtk/build
ccmake ../path/to/vtk/source  // -GNinja may be added to use the Ninja generator

配置参考的是link

// 按照VTK tutorial要求，每设置完一项均按'c'进行一次configuration，直到所有项目设置完
// Enter键更改选项
BUILD_SHARED_LIBS = ON   
BUILD_TESTING = ON // 默认OFF，如果打开的话，编译时会由于下载测试数据所用url过旧而报错，建议OFF
CMAKE_BUILD_TYPE = Release    // 默认Debug运行会较慢
CMAKE_INSTALL_PREFIX = /usr/local   // 这里用默认就行，或者改到想要安装的位置
//以下为高级设置，需先在命令行按't'才可见，再次按't'可退出高级设置
VTK_FORBID_DOWNLOADS = ON    // 默认OFF，建议打开，否则编译会报错，理由同BUILD_TESTING

VTK_USE_CUDA=ON // 我自己改的

//此时应已经出现'g' generating 的按键选项，按 'g' 即完成配置.

安装

cmake .
make -j4
sudo make install

四、重新编译Opencv

亲测不用卸载OpenCV即可重新编译，没下载Opencv的也可以直接参考我的另外一篇安装Opencv，前面的配置都一样，只需要更改cmake选项。

 cd /...Path to OpenCV build.../build

更改cmake选项，下面是完整的。

sudo cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D WITH_TBB=ON \
-D ENABLE_FAST_MATH=1 \
-D CUDA_FAST_MATH=1 \
-D WITH_CUBLAS=1 \
-D WITH_CUDA=ON \
-D BUILD_opencv_cudacodec=OFF \
-D WITH_CUDNN=ON \
-D OPENCV_DNN_CUDA=ON \
-D CUDA_ARCH_BIN=5.0 \
-D WITH_V4L=ON \
-D WITH_QT=ON \
-D Qt5_DIR=/home/gao/Qt5.9.0/5.9/gcc_64/lib/cmake/Qt5 \
-D WITH_OPENGL=ON \
-D WITH_VTK=ON \
-D WITH_GSTREAMER=ON \
-D OPENCV_GENERATE_PKGCONFIG=ON \
-D OPENCV_PC_FILE_NAME=opencv.pc \
-D OPENCV_ENABLE_NONFREE=ON \
-D OPENCV_EXTRA_MODULES_PATH=/home/gao/opencv_contrib/modules \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D INSTALL_C_EXAMPLES=OFF \
-D BUILD_EXAMPLES=ON \
-D GLIBCXX_USE_CXX11_ABI=0 ..

更改的部分

-D WITH_QT=ON \
-D Qt5_DIR=/home/gao/Qt5.9.0/5.9/gcc_64/lib/cmake/Qt5 \
-D WITH_OPENGL=ON \
-D WITH_VTK=ON \

Qt5_DIR这个不设置的话cmake会报错，

  Could not find a package configuration file provided by "Qt5" with any of
  the following names:

    Qt5Config.cmake
    qt5-config.cmake

  Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
  to a directory containing one of the above files.  If "Qt5" provides a
  separate development package or SDK, be sure it has been installed.

也可参考link，要将Qt5_DIR设置为Qt5Config.cmake所在的路径

For find_package to be successful, CMake must find the Qt installation in one of the following ways:

Set your CMAKE_PREFIX_PATH environment variable to the Qt 5 installation prefix. This is the recommended way.
Set the Qt5_DIR in the CMake cache to the location of the Qt5Config.cmake file.

安装

make -j4
sudo make install

环境配置参考前面博客。

五、输出general configuration for opencv

mkdir OpenCV_configuration
cd OpeCV_configuration

main.cpp

vim main.cpp
// 代码如下

#include <stdlib.h>
#include <fstream>
#include <string>
#include <iostream>
using namespace std;

#include <opencv2/opencv.hpp>

int main(void) {
  ofstream fout("OpenCV_general_configuration.txt");
  fout << cv::getBuildInformation() << endl;
  fout.close();
}

CMakeLists.txt

# cmake needs this line
cmake_minimum_required(VERSION 3.1)

# Define project name
project(Configuration)

# Requires OpenCV
find_package(OpenCV 4.5.0 REQUIRED)
# Show a message with the opencv version detected
MESSAGE("OpenCV version : ${OpenCV_VERSION}")
include_directories(${OpenCV_INCLUDE_DIRS})
link_directories(${OpenCV_LIB_DIR})

# Enable C++11
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED TRUE)

# Declare the executeable target built from your sources
ADD_EXECUTABLE(${PROJECT_NAME} main.cpp)

# Link your application with OpenCV libararies
target_link_libraries(${PROJECT_NAME} ${OpenCV_LIBS})

compile

mkdir build
cd build
cmake ..
make
./Configuration

输出
