纯净版Ubuntu18.04安装cuda10.2 OpenCV4.1.0 PCL1.8.0 QT5
注：以下操作都在重装后的ubuntu进行
一.cmake 自定义版本安装
！！！！！！！！！！！！！！！！！！！！！！！！！！！！1
千万不要 apt-get autoremove cmake 否则重装系统吧
autoremove删除很多依赖，后续编译安装其他软件出现奇怪错误
！！！！！！！！！！！！！！！！！！！！！！！！！！！！！
1.下载
wget https://cmake.org/files/v3.9/cmake-3.9.1-Linux-x86_64.tar.gz
tar zxvf cmake-3.9.1-Linux-x86_64.tar.gz
2.创建软链接
mv cmake-3.9.1-Linux-x86_64 /opt/cmake-3.9.1
ln -sf /opt/cmake-3.9.1/bin/* /usr/bin/
二nvidia驱动–cuda10.2
1.nvidia驱动

2.cuda10.2*.run安装

3.测试:
nvidia-smi
nvcc -V
三.ubuntu 18.04 安装 opencv
1.依赖安装
https://blog.csdn.net/ColorKin/article/details/83781197?utm_medium=distribute.pc_relevant.none-task-blog-BlogCommendFromMachineLearnPai2-1.add_param_isCf&depth_1-utm_source=distribute.pc_relevant.none-task-blog-BlogCommendFromMachineLearnPai2-1.add_param_isCf
1.1其他依赖安装：
sudo apt-get install libgoogle-glog-dev ccache libgtk-3-dev libgoogle-glog-dev

1） 安装依赖包
sudo apt-get install libpng-dev libjpeg-dev libtiff-dev zlib1g-dev
sudo apt-get install gcc g++
sudo apt-get install autoconf automake libtool checkinstall
cd ~
wget http://www.leptonica.org/source/leptonica-1.73.tar.gz
tar -zxvf leptonica-1.73.tar.gz
cd leptonica-1.73
./configure
make sudo checkinstall
sudo ldconfig
2）下载tessearct
cd ~
git clone https://github.com/tesseract-ocr/tesseract.git
cd tesseract
./autogen.sh

#install tesseract latest
2.cmake添加
cmake -D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-10.2 \
-D WITH_PYTHON=OFF \
-D BUILD_TIFF=ON \
-D WITH_CUDA=ON \
-D BUILD_TESTS=OFF \
-D BUILD_PERF_TESTS=OFF \
-D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D BUILD_opencv_python2=OFF \
-D BUILD_opencv_python3=OFF \
-D CUDA_ARCH_BIN=7.5 \
-D OPENCV_CUDA_ARCH_PTX='' \

-D OPENCV_GENERATE_PKGCONFIG=ON \
-D OPENCV_EXTRA_MODULES_PATH=/home/zzq/opencv-4.1.0/opencv_contrib-4.1.0/modules ../
3.编译
make -j$(nproc)
4.安装
sudo make install
四.PCL安装
sudo apt-get update
sudo apt-get install git build-essential linux-libc-dev
sudo apt-get install libusb-1.0-0-dev libusb-dev libudev-dev
sudo apt-get install mpi-default-dev openmpi-bin openmpi-common
sudo apt-get install libflann1.8 libflann-dev
sudo apt-get install libeigen3-dev
sudo apt-get install libboost-all-dev

sudo apt-get install freeglut3-dev pkg-config
sudo apt-get install libxmu-dev libxi-dev
sudo apt-get install mono-complete
sudo apt-get install openjdk-8-jdk openjdk-8-jre
error1:
- sudo apt-get install libflann1.8 libflann-dev，显示无法定位包libflann1.8，使用sudo apt-get update和sudo apt-get upgrade也没有解决问题。后来在Ubuntu packages上面看到ubuntu 18.04 bionic对应的版本是libflann1.9，改用libflann1.9执行成功。
sudo apt-get install libflann1.9 libflann-dev sudo apt-get install libflann1.9 libflann-dev
cd pcl
mkdir release
cd release
cmake -DCMAKE_BUILD_TYPE=None -DCMAKE_INSTALL_PREFIX=/usr \ -DBUILD_GPU=ON-DBUILD_apps=ON -DBUILD_examples=ON \ -DCMAKE_INSTALL_PREFIX=/usr ..
make -j$(nproc)
error2:

Checking for module ‘metslib’
– No package ‘metslib’ found
安装metslib
下载链接

（文章后看能否上传资源）
解压后，在metslib-0.53打开命令终端：
执行:
sudo sh ./configure
sudo make
sudo make install。
顺利完成安装metslib.

cd ~ //先返回到根目录
sudo vim /etc/ld.so.conf //获取超级权限，并用vim编辑器打开该文件
末尾加入 /usr/local/lib即可
sudo ldconfig //退出后执行下面的语句使之生效
