Qt Application Development

We have two ways to build a Qt project: the command line mode and the gui mode. We have a description as follow:

Setup Environment in command line mode

If you want to build C, C++, Qt and other linux application, there is a magical script to use. It’s environment-setup in the $(BSP_ROOT)/cross_compiler/linux-devkit directory. To build some linux application, you just need to excute this script as follow, and then everything will be ok.

$ cd  $(BSP_ROOT)/cross_compiler/linux-devkit> 
$ source  environment-setup

After this, you can buid Qt project. For example, we have a calculator qt demo to build as follow:

$  cd  $(demo)/calculator
$  ls 
button.cpp  button.h  calculator.cpp  calculator.h  calculator.pro  main.cpp
$  qmake calculator.pro   ## Generating a makefile
$  make  	## If no error, a binary will be generated after make.
