Qt5 runtime error, primary problem! !

With Qt to create a default program. Compile connections are through. An error occurred while running exe file: Failed to load platform plugin "windows". Available platforms are:



tell me how to do? Msvs2010 Qt is installed, and also installed visual add on plug-ins. Whether in Qt or vs2010 in will not work.
------ Solution ---------------------------------------- ----

IDE li is also not up and running, the program in question.
single-step debugging, to find the wrong place.

if it is double click exe, it is missing dll. Qt library dll is not in default environment variable.

plugin windows encapsulated in plugins / platforms / qwindows.dll (seems to be) in

I missing DLL, it had never been a similar error. Which always prompts missing DLL, or simply no response.

My experience is generally always somewhere in the program there is an error: then use qDebug () or cout locate which line error, and then gradually find out the real reason.

I put this program into the qt installation directory's bin folder. What dll that there should have it. But still this error!

VS to run how about?

is the same!

certainly a question of procedure.

at least to these bars, in the bin folder ~ ~ pulled the project folder

procedures should be no problem. I was directly using qt wizard to create a program, that did not turn over.

I pulled the generated exe file in the bin folder, or not.

sent me the source code, I see:

QT is the wizard to create a program. I chose Qt GUI.

someone know?

Today I have encountered this problem! Search for a long long time did not try to solve ...... if you tell me, oh resolved.
I vs2010 under confused, Ctrl + F5 perform no problem, that is, double-click the exe file error.

Is there no one knows how to do? Thank you first! !
------ For reference only -------------------------------------- -

normal operating procedures in the IDE, indicating that the program is no problem,
Double exe can not run because: Qt's dll is not in the system environment variables, exe can not find the Qt dll. The need to copy the dll to the exe directory just fine.

This is not my mistake. My mistake though, and hints about this error, but under vs2010. ide also appeared in this issue.

I use the qt files generated by the wizard, no changes. Compiler no problem. Found that a single-step debugging:
QApplication a (argc, argv);

appeared that an execution error.

has been resolved! As long as all the Replace like.

This is because of the need to load called "windows" this plugin, but did not find this plugin (that DLL libraries)
QT QT installed by default in the directory% QTDIR \ plugins automatically find and load

1. using copy library files to the system $ PATH directory can solve the problem, but it will later update the library file version when it is easy to cause problems;
2. If using VS editor, then you can modify the project properties corresponding path settings can also solve the problem;
3. The best way is through QApplication :: addLibraryPath (...) to increase library load path, such as
Code: QApplication :: addLibraryPath (QApplication :: applicationFilePath () + QDir :: separator () + "plugins");, publisher when the QT installation directory in plugins or select an entire folder of the library must be copied to the run the program the same directory

What All reload? Reload VS2010, reinstall Qt?
------ For reference only ------------------------------ ---------
main.cpp in into QApplication a (argc, argv); on OK

landlord, how back thing. Trouble that the next! All reload? Explain! Thank you!

do not have all the heavy equipment, just add a dll can be friends, is this libEGLd.dll (debug version)
