Qt program in cygwin

From http://blog.sina.com.cn/s/blog_49366773010008c7.html

I have done QT on windows, so I also want to try the QT program under cygwin, but it is a pity that only qt3 is used.

To run the QT program, you also need to start xwindows. (The command to start X Window in cygwin is startx.)

# Include

<Qapplication. h>

# Include <qpushbutton. h>

Int main (INT argc, char ** argv)

{

Qapplication A (argc, argv );

Qpushbutton Hello ("Hello world! ", 0 );

Hello. Resize (100, 30 );

A. setmainwidget (& Hello );

Hello. Show ();

Return a.exe C ();

}

G ++ compilation instructions:

G ++ qt2.cpp-O qt2-I/usr/include/qt3-L/lib/qt3/lib-lqt

 

Notes:

I have never been very familiar with the G ++ switch. I don't know how to reference the non-standard G ++ header file directory,

The case sensitivity of the switch in G ++ has special meanings:-I indicates an include directory, and-I indicates the specific include file name;

-L indicates the directory of Lib, and-l indicates the name of link Lib.

 

You are welcome to share your cross-platform and C ++ knowledge with me.
