Qt4.8 three programming environments built under Windows

Qt4.8 three programming environments built under Windows

QT version is divided according to different graphics system, currently divided into four versions: Win32 version, for the Windows platform, X11 version, suitable for the use of the X system of various Linux and UNIX platforms; Mac version, suitable with Apple macosx;embedded version, Suitable for Linux platforms with framebuffer (frame buffer).

Qt-embedded and Qtopia

Qt in the first time, for Linux and UNIX systems, only built on Xlib on the X11 version. However, with the application of Linux operating system in the embedded field, QT introduced the embedded version qt-embedded (Qte). Because the embedded hardware environment is often difficult to run a large x server, QT embedded version skipped the Xlib and Xserver direct operation frame buffer, can be greatly improved in speed and volume.

Qtopia was originally an open source project on SourceForge.net, full of QT palmtop Environment, a desktop-like application built on the QTE, including PDA and mobile phones and other handheld systems such as phone book, calendar, etc. Now Qtopia has become one of Trolltech's flagship products, providing a complete graphical environment for both PDA and mobile phones based on the Linux operating system.

The relationship between Qte and Qtopia deserves special attention. Prior to version 4, QTE and Qtopia were two different sets of programs, Qte was the base Class library, and Qtopia was a series of applications built on top of QTE. But starting with version 4, Trolltech qte into Qtopia and launched a new Qtopia4. In this version, the original qte is called Qtopia Core, as the core of the embedded version, can be used in conjunction with Qtopia or standalone. The original Qtopia is divided into several layers, the core application framework and plug-in system is called Qtopia Platform, the upper layer of the application according to different target users are divided into different packages, such as Qtopai Pda,qtopia Phone.

There is a need to note that Qtopia has not been out of the 3.x version, directly from version 2.20 to the 4.x version, I think this is mainly to integrate Qte, and QT version to keep in sync.

Simply put, QTE is the underlying class library of the embedded version, and the QT application is written based on this class library. After the QTE4 version was renamed Qtopia Core, it is not the same as Qtopia, just a class library, and no desktop environment, like our usual qtopia-core-opensource-src-4.3.5.

And with Qtopia desktop environment is qtopia-opensource-src-4.x.x, directory under a few more files.

Now the common Qtopia is 1.7.0 version and 2.2.0 version, but they use the QTE is 2.x version, we use 4.3.5 version of the program can not run on it, and now about QTOPIA4 introduction is not many, with said Qtopia4 no PDA version, There is a mobile version, but the interface is not Qtopia2 good

Learn about the supported platforms, compilers, and debuggers from the QT website:

This article mainly explains QT in the Windows operating system under the three kinds of programming environment constructs.

Scheme	Programming environment	Compiler	Debugger
One	Qt Creator	MinGW GCC	Gdb
Two	Qt Creator	Microsoft Visual C + + Compiler	Debugging Tools for Widows
Three	Microsoft Visual Studio 2010	VS2010 comes with	VS2010 comes with

Note that the QT Installer and compression package mentioned in the following scenarios can be downloaded to http://download.qt.io/official_releases/on the website.

QT compiler MinGW:

QT Debugger GDB:

http://download.qt.io/development_releases/prebuilt/gdb/

Scenario One: Qt4.8.5for Windows (Qt creator+mingw)

1, install the compilation environment Qt-creator-win-opensource-3.0.0.exe first. Use the default path, C:\Qt\qtcreator-3.0.0.

2. Unzip the compiler tool Mingw-gcc440_1.zip. Please copy the inside folder MinGW to the path C:\QT\MINGW.

3. Unzip the debugger tool Gdb-7.5-i686_winxp.zip. (http://download.qt.io/development_releases/prebuilt/gdb/windows-xp/)

Please copy the inside folder Gdb-7.5-i686_winxp to the path C:\Qt\gdb-7.5-i686_WinXP.

4, the final installation library file Qt-win-opensource-4.8.5-mingw.exe.

The default installation path for QT is C:\Qt\4.8.5, which is proposed to be modified to C:\Qt\4.8.5_MinGW, which is intended to be separate from other QT repository areas. Avoid overwriting and destroying other QT versions that have been installed. (Note: The QT library that supports the Windows environment has mingw,vs2010,vs2008, etc.)

When the installation prompts find installed MinGW, the user points to the path C:\QT\MINGW.

5. After completing the steps above, perform the desktop shortcut qt Creator.

(1) Enter the software----menu, tools----Build and run manual settings,->QT version, add qmake path C:\Qt\4.8.5_MinGW\bin\qmake.exe.

(2) Build and run Build kit (KIT) with the tools---------------------------

Manager---Edit, browse, point to Debugger path C:\Qt\gdb-7.5-i686_WinXP\gdb-i686-pc-mingw32.exe.

The QT version is selected as "Qt 4.8.5 (4.8.5_MINGW)".

(3) Go to software----menu, tools----Build and run manual settings, compiler--------add MinGW, and set the appropriate path. Compiler path C:\Qt\mingw\bin\gcc.exe.

6. Accelerate QT compilation speed skills.

QT Default compilation is very slow, you can use the multi-core compilation method to improve speed.

Replace the Mingw32-make.exe with Jom.exe when you enter the software and open the project, such as build and run, projects, toolbars, and so on.

*************************

If it is qt4.8.6/qt4.8.7 for Windows (Qt Creator+mingw), the situation differs from Qt4.8.5. For example, the Qt4.8.6 environment is built as follows:

1, first install the IDE compilation environment Qt-creator-opensource-windows-x86-3.1.1.exe. Use the default path, C:\Qt\qtcreator-3.1.1.
2. Unzip the MinGW compiler tool i686-4.8.2-release-posix-dwarf-rt_v3-rev3.7z. (http://download.qt.io/development_releases/prebuilt/mingw_32/)

Please copy the inside folder MinGW to the path C:\QT\MINGW32.
3, the final installation library file Qt-opensource-windows-x86-mingw482-4.8.6-1.exe.
The default installation path for QT is C:\Qt\4.8.6, which is proposed to be modified to C:\Qt\4.8.6_MinGW, which is intended to be separate from other QT repository areas.
Avoid overwriting and destroying other QT versions that have been installed. (Note: The QT library that supports the Windows environment has mingw,vs2010,vs2008, etc.)
When the installation prompts find installed MinGW, the user points to the path C:\QT\MINGW32.
4. After completing the steps above, perform the desktop shortcut qt Creator.
(1) Enter the software----menu, tools----Build and run manual settings,->QT version, add qmake path C:\Qt\4.8.6_MinGW\bin\qmake.exe.
(2) Go to software----menu, tools----Build and run manual settings, compiler--------add MinGW, and set the appropriate path.
Compiler path C:\qt\mingw32\bin\g++.exe.
(3) Go to Software---menu---Tools----build and run the debugger, manual settings, add MinGW Debugger, and set the appropriate path.
Debugger path C:\Qt\mingw32\bin\gdb.exe.
(4) Build and run Build kit (KIT) with the tools-------------------------------
The QT version is selected as "Qt 4.8.6 (4.8.6_MINGW)".
5. Accelerate QT compilation speed skills.
QT Default compilation is very slow, you can use the multi-core compilation method to improve speed. See 5.
Replace the Mingw32-make.exe with Jom.exe when you enter the software and open the project, such as build and run, projects, toolbars, and so on.
6, modify the environment variables.
Manually or using a third-party tool rapid Environment Editor, add the Qt path C:\Qt\4.8.6_MinGW\bin to the system variable path.
