安装联咏交叉编译链

9852x/9856x

0.创建编译链目录

sudo mkdir /usr/local/arm

1.解压编译链

tar -xjvf arm-ca9-linux-gnueabihf-6.5.tar.bz2

2.将解压后的目录放到编译链目录下

sudo cp arm-ca9-linux-gnueabihf-6.5 /usr/local/arm/ -r

3.配置环境变量

sudo vim /etc/profile

在/etc/profile底部追加交叉编译链环境变量

# Novatek NT9856X
export PATH="/usr/local/arm/arm-ca9-linux-uclibcgnueabihf-8.4.0/bin:$PATH"
export LD_LIBRARY_PATH="/usr/local/arm/arm-ca9-linux-uclibcgnueabihf-8.4.0/lib:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH="/usr/local/arm/arm-ca9-linux-uclibcgnueabihf-8.4.0/arm-ca9-linux-uclibcgnueabihf/lib:$LD_LIBRARY_PATH"

# Novatek NT9852X
export PATH="/usr/local/arm/arm-ca9-linux-gnueabihf-6.5/bin:$PATH"
export LD_LIBRARY_PATH="/usr/local/arm/arm-ca9-linux-gnueabihf-6.5/lib:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH="/usr/local/arm/arm-ca9-linux-gnueabihf-6.5/arm-ca9-linux-gnueabihf/lib:$LD_LIBRARY_PATH"

source /etc/profile

不同用户或同一用户不同的CLI窗口无法正确找到编译命令时，也需要source /etc/profile重新刷一下环境变量
