Prerequisites

Debian10(buster) is highly recommended OS to develop.

Installing required packages

Please login and perform the following commands:

$ sudo apt-get install -y build-essential 
$ sudo apt-get install -y qtcreator 
$ sudo apt-get install -y qt5-default 
$ sudo apt-get install -y qt5-doc 
$ sudo apt-get install -y qt5-doc-html qtbase5-doc-html 
$ sudo apt-get install -y qtbase5-examples 
$ sudo apt-get install -y qt5-qmake 
$ sudo apt-get install -y rsync
$ sudo apt-get install -y gcc-8-arm-linux-gnueabihf g++-8-arm-linux-gnueabihf
$ sudo apt-get install -y gcc-8-aarch64-linux-gnu g++-8-aarch64-linux-gnu

Link arm-linux-gnu*-8 to arm-linux-gnu* and aarch64-linux-gnu*-8 to aarch64-linux-gnu*:

$ sudo su
$ cd /usr/bin
$ for f in $(ls arm-linux-gnu*-8);do ln -sf $f $(echo $f|sed "s/-8//");done 
$ for f in $(ls aarch64-linux-gnu*-8);do ln -sf $f $(echo $f|sed "s/-8//");done
$ exit

Installing cross toolchain

Please download RK3288(Password: gm9i) 、 RK3399(Password: 0kkn) and (Password:)cross compiler toolchain first. Then execute the following command to unzip the cross compiler tool to the /opt directory

For RK3288

$ sudo rm -rf /opt/toolchain_Qt_V5.11.3/rk3288/
$ sudo mkdir -p /opt/toolchain_Qt_V5.11.3/rk3288/
$ sudo tar -zxf rk3288_toolchain_Qt_V5.11.3_*.tar.gz -C /opt/toolchain_Qt_V5.11.3/rk3288/

For RK3399

$ sudo rm -rf /opt/toolchain_Qt_V5.11.3/rk3399/ 
$ sudo mkdir -p /opt/toolchain_Qt_V5.11.3/rk3399/ 
$ sudo tar -zxvf rk3399_toolchain_Qt_V5.11.3_*.tar.gz -C /opt/toolchain_Qt_V5.11.3/rk3399/

For RK3568

$ sudo rm -rf /opt/toolchain_Qt_V5.11.3/rk3568/
$ sudo mkdir -p /opt/toolchain_Qt_V5.11.3/rk3568/
$ sudo tar -zxf rk3568_toolchain_Qt_V5.11.3_*.tar.gz -C /opt/toolchain_Qt_V5.11.3/rk3568/
