Nano上配置realsense D435相機

步驟：

• cmake

1）下載cmake-3.8.2.tar.gz : https://cmake.org/files/

or https://blog.csdn.net/qq_42393859/article/details/85251356

2) 在主文件夾下新建tools/文件夾，將cmake-3.8.2.tar.gz解壓之後放在tools/中，爲了防止出現權限不足問題，直接對文件更改權限：
解壓：sudo tar -zxvf cmake-3.8.2.tar.gz
賦權限：sudo chmod -R 777 cmake-3.8.2

3)a安裝gcc-c++:
sudo apt-get install build-essential
或者直接執行這兩條命令

sudo apt-get install gcc
sudo apt-get install g++

4)進入文件夾下執行以下命令：

 sudo ./bootstrap
 sudo make
 sudo make install

5)查看是否安裝成功以及安裝版本：

cmake --version

• 下載SDK源碼：

mkdir -p  ~/tools/
cd ~/tools/
git clone https://github.com/IntelRealSense/librealsense.git
cd librealsense

• 安裝依賴：

sudo apt-get install git libssl-dev libusb-1.0-0-dev pkg-config libgtk-3-dev
sudo apt-get install libglfw3-dev libgl1-mesa-dev libglu1-mesa-dev

• 先拔掉相機的USB線
• 執行權限設置，建立別名

./scripts/setup_udev_rules.sh

• 增加模塊

echo 'hid_sensor_custom' | sudo tee -a /etc/modules

• 添加變量到環境

export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH

• 編譯
• 增加cuda支持

mkdir build 
cd build
cmake ../ -DBUILD_EXAMPLES=true -DBUILD_WITH_CUDA=true
sudo make uninstall && make clean && make && sudo make install

一直卡在了：

打開cmakelist.txt

勾選Python選項

換成其他Python，帶有torch環境的，後續檢測+深度

勾選example

mkdir build && cd build
cmake ../ -DBUILD_EXAMPLES=true
sudo make uninstall && make clean && make -j8 && sudo make install

• 安裝完成後，相應目錄位於：

The shared object will be installed in /usr/local/lib
header files in /usr/local/include.
The binary demos, tutorials and test files will be copied into /usr/local/bin

測試：

• 測試例子：

cd ~/tools/librealsense/build/examples/capture
./rs-capture 

• 效果如下：

轉存失敗重新上傳取消

 期間遇到的問題在此記錄一下：

1、

sudo apt install libssl-dev 時報錯，報錯信息如下

The following packages have unmet dependencies:
 libssl-dev : Depends: libssl1.1 (= 1.1.0g-2ubuntu4) but 1.1.0g-2ubuntu4.3 is to be installed
              Recommends: libssl-doc but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

cmake ../ -DBUILD_EXAMPLES=true -DBUILD_WITH_CUDA=true 這一步時出現了下面的錯誤

-- GLFW 3.3 not found; using internal version
-- Could NOT find Vulkan (missing:  VULKAN_LIBRARY VULKAN_INCLUDE_DIR) 
-- 

-- Configuring incomplete, errors occurred!

然後我又下載編譯GLFW也不行，編譯時也報錯中斷，網上搜索時，看到了這個提問，非常感謝

https://.com/questions/620601/-install-libsdl2-dev-or-cmake-glfw-libxinerama-dev-problem

在命令行執行sudo apt-get install libxinerama-dev

Using X11 for window creation  CMake Error at third-party/glfw/CMakeLists.txt:235 (message):

The Xinerama headers were not found錯誤得以解決

再次配置編譯GLFW，參考此文章：https://blog.csdn.net/xyh930929/article/details/83745958

關於glfw，可觀看次文章：https://blog.csdn.net/zjz520yy/article/details/83000081

之前報的GLFW 3.3 not found; using internal version錯誤得以解決
