¶ Linux Application Development (Calling Hardware)
This tutorial takes ubuntu-22.04.x-desktop-amd64 as an example. The basic tools used for application development are installed as follows:
#update soft list
sudo apt-get update
# install make
sudo apt install make
sudo apt -y install make-guile
#install gcc g++
sudo apt -y install gcc
sudo apt -y install g++
# install cmake
sudo snap install cmake
sudo apt -y install cmake
#install git
sudo apt -y install git build-essential dkms --force-yes
#install vim
sudo apt -y install vim
#install curl
sudo apt -y install curl
#install wget
sudo apt -y install wget
2、For Linux application development, knowledge reserves required: basics of C/C++ programming development, basics of make compilation and Makefile writing.
