bracelet power Qt program released under windows [

[balancer02]

If you do not need the other plug-ins, it can be released program, yet many students complain jpg, gif, bmp image formats can not be displayed, because Qt native support for png, and other formats need to plug-in support (plug-in% QTDIR% / plugins imageformats directory)

this problem, in fact, the manual explained Qt has been relatively clear. Here is my understanding and according to their own experiment to write something, I hope a little easier to understand than the Qt documentation.


Mingw
myprogram.exe Microsoft.VC90.CRT *
Qt program released under the windows

Perhaps you have to ask, if you do not want to install the redistributable package how to do, such as the need to want a dll and procedures for packaging, we can do this:
Note:
qmake
mingw32-make release
the executable file and will need a dynamic library into the same folder, it normally takes
If you are using VS2008 and not mingw, published in fact basically the same procedure.
Similarly, If your program needs to gb2312, gbk encoding support, then you need to% QTDIR% plugins codecs directory,power balance, copy the appropriate plug-in directory where the executable under the codecs directory

If the user has installed on the machine redistributable package, the program will never use Microsoft.VC90.CRT under the library. When using this method, if also released plug-ins (including pictures plug-in,bracelet power, etc.), then the plug-in must be compiled:
myprogram.exe imageformats qjpeg4.dll imageformats qgif4.dll ...
msvc
CONFIG-= embed_manifest_dll
makes the generated plug-in manifest file is not embedded in, or plug-in is not recognized by the program (in fact, can also be identified, as long as a copy of the Microsoft.VC90.CRT plug into the same folder and can,power balance bands, of course, this approach is well, if the plug-in located in several directories, a lot of copies to be placed Microsoft.VC90.CRT).
the folder (if you're using VS2008 express, the folder does not exist)
VC redist Microsoft.VC90.CRT
directly copied into the executable directory
2. the best tool for a process view, such as Microsoft's Process Explorer, etc., in the end your program to see what dynamic libraries are loaded (which plug-ins are loaded)
you simply need to plug into the executable copy of the directory where the imageformats directory can be

first release patterns generated executable file
vc because it is compiled, so do not mingw's mingwm10.dll libgcc_s_dw2-1.dll, replaced with the VC2008's C C + + runtime library:
recommended: may wish to see more of Qt installation directory under the plugins directory, and familiar with these plug-ins are what it does, what you need to publish the program.
myprogram.exe qtcore4.dll qtgui4.dll imageformats * 4.dll ...
myprogram.exe mingwm10.dll libgcc_s_dw2-1.dll qtcore4.dll qtgui4.dll
If you are using Windows xp system before, then just run the library and the two executable program can be put in the same directory.
static compilation does not involve the following (static compilation can see here), contains only dynamic compilation (that is, Qt by default), the main mingw and msvc is divided into two cases:
First, we need to generate a release mode executable program (many students complain that it takes a little more than 100 M program a dynamic library, because with the debug)
some students complain dynamic library copy in the past, the program can not locate the procedure entry point error in the dynamic link library QtCore4.dll, this is generally due to the system are installed with the operation of multiple sets of Qt library, and you do not copy Qt library installation directory caused. For example, when installing the Qt SDK, it is easy to cause this problem, because it's Qt is a mingw compiler, but the inside is a msvc compiled QtCreator, so many people do not care for it QtCreator copy with the Qt runtime over the.
1. Always remember: Dependency Walker is a good helper for you, it will tell you your exe and dll What are the library, and it loads the dynamic library in which folder, etc.



but for Windows xp (included) after the system, this will not work correctly, the program will report: application configuration is incorrect because the application failed to start. This seems complicated, but solution is simple, just installed on the user's machine more than 1M VS2008 redistributable package vcredist_x86.exe can
Now, the program can be released. You can now also to create an installation package nsis.
the package will be installed to run the library window WinSxS directory under the system directory under the previous system of xp, but also will be installed to run the library path of the directory path. In fact, if the user had installed the VC2008 other people write the procedures, it should already be installed on the machine over the package.

MSVCR90.DLL MSVCP90.DLL
qmake
nmake release
then prepare the required dynamic libraries and plug-ins

myprogram.exe codecs qcncodecs4.dll ...
