nvr-easynvr

1. 切换到 root 权限 sudo su，提示输入密码，输入密码即可
2. 安装vim

 sudo apt install vim

3. 添加海思编译环境

tar -jxvf hisi-linux-nptl.tar.bz -C /opt
vim  /etc/profile 修改环境变量
添加到最后：
export PATH="/opt/hisi-linux-nptl/arm-hisiv100-linux/target/bin:$PATH"

4. 使环境变量生效

source /etc/profile

5. 创建目录 /home/nvr-demo/hisi

   cd  /home
   mkdir nvr-demo
   cd nvr-demo
   mkdir hisi

6. 解压nvr_target.tar.bz 到/home/nvr-demo/hisi

tar -jxvf nvr_target.tar.bz -C /home/nvr-demo/hisi

7. nvr_target 文件名改成 nvr

mv nvr_target nvr

8. 安装make 指令

sudo apt-get install make

9. 编译

/home/nvr-demo/hisi/nvr/buildStaticlibrary.sh
/home/nvr-demo/hisi/nvr/source/ProductBuilder/General/General/_8channel_nvr/mkimage.sh

mkimage.sh 执行如果报错，则

vim mking.sh

mksquashfs /home/root/share//ProductBuilder/romfs/   主要是文件路径不对

创建 nvrdev 目录：

mkdir /home/nvr-demo/hisi/nvrdev

novartek 环境搭建

如果没有权限，新进入root ```java sudo su

1.	安装依赖 参考NOVATEK_SDK_INSTALL.pptx
```java
sudo apt-get update
sudo apt-get -y dist-upgrade
sudo apt-get clean
sudo apt-get autoremove
sudo apt-get install build-essential libc6-dev lib32ncurses5-dev libncurses5-dev libncurses5:i386 libgl1-mesa-dev g++-multilib mingw-w64 tofrodos lib32z1 u-boot-tools zlib1g-dev bison libbison-dev flex mtd-utils vim squashfs-tools gawk cmake cmake-data liblz4-tool libmpc3 libstdc++6 device-tree-compiler android-sdk-libsparse-utils android-sdk-ext4-utils texinfo python3-pyelftools python3-crypto libssl-dev

2. 安装 toolchain 编辑工具 参考 NT98331_SDK_release_v3.03.108_ns_glib_A64.tar\NT98331_SDK_release_v3.03.108_ns_glib_A64\NT98331_SDK\software\board\document 3.1章节

Mkdir /opt/ivot sudo tar –jxvf aarch64-ca53-linux-gnueabihf-8.4.01.tar.bz2 -C /opt/ivot

3.	sdk 安装
sdk路径 NT98331_SDK_release_v3.03.108_ns_glib_A64.tar\NT98331_SDK_release_v3.03.108_ns_glib_A64\NT98331_SDK\software\board
 ```java
mkdir /home/dream/novatek
tar –jxvf na51103_linux_sdk.tar.bz2

4. 变更Shell 的 symbolic link ls -l /bin/sh //先查看一下連結的shell 是不是bash, 若不是就要進行切換 删除/bin/sh

  rm –rf /bin/sh
  ln -s /bin/bash /bin/sh	//將symbolic link要換成/bin/bash

5. 在sdk解压的路径（na51103_linux_sdk）下面新建build.sh 编译脚本

   cd /home/dream/na51103_linux_sdk  //进入sdk 的目录
   vim build.sh //创建build.sh 文件

build.sh 文件

#!/bin/bash
echo "set environment"
source build/envsetup.sh
echo "set mode"
lunch
echo "build start"
make all

增加build.sh 为可执行

   chmod 777 build.sh
