New command line qt project, and compile the package

ref: https://blog.csdn.net/weixin_42837024/article/details/81945656

Platform: Ubuntu 18.04

QT version: 5.9.1 (Open Source)

g++　　　　 ： 7.3.0
arm-gcc　　 ：4.8.1

 

New Project

• New folder, as the project root directory
• Write main.cpp
  main.cpp

#include<QApplication>
#include<QWidget>
int main(int argc,char ** argv)
{
    QApplication app(argc,argv);
    QWidget* pWidget = new QWidget();
    pWidget->show();
    return app.exec();

}

 

 

 

• Into the appropriate folder input qmake -projectwill find a folder created under the platform-independent project file a XXX.pro files (and folders in front of the same name)
  • qmake -project
    

• Enter the next step qmake XXX.proyou have to enter the corresponding pro file
  • qmake XXX.pro
  • Generate some makefile file and debug and release folders ( because handwritten Makefile is more difficult and error-prone, especially the need to write Makefile to several different platforms and compilers combined use qmake, developers create a simple "project" file and run qmake generates the appropriate Makefile.qmake will pay attention to all dependent compiler and platform, developers can be freed only interested in their code )

Compile

If you are using the open-source version of Qt, with the make; if it is a commercial version of Qt, with nmake

• So I enter make, will complain, do not worry

 

Because we use QWidget so to join in the pro file QT += widgetsand then continue to repeat the previous step

•  Re-make
  • 　　make

 

Results shown in Figure

They are packaged under different platforms also not the same. But the principle is similar, the application files are dependent on library put under the same directory

• Windows
  • Enter the command windeployqt XXX.exe
  • Enigma Virtual Box can then use the files are packaged together
• Linux

 1. The resulting compiled executable program (such as: test) copied to an empty directory

 2. Use the ldd command to view and export the required libraries

Pack.sh a new file in the directory in step 1, the file follows:

#你需要发布的程序名称
bin="test_project"

# 输出路径
des="./"
deplist=$(ldd $bin | awk  '{if (match($3,"/")){ printf("%s "),$3 } }')
cp $deplist $des

即可
