Application was unable to start correctly (0xc000007b)

Question

I am unable to debug the application, always getting I am using the following configuration: QT 5.3.0 MSVC 2012 64bit Compilation. 我正在使用以下配置：QT 5.3.0 MSVC 2012 64位编译。 I added the following libs to my linking: Qt5Core.lib;Qt5Gui.lib;Qt5Widgets.lib; Optionally I tried to add the following as well (out of despair): qtmain.lib;libEGL.lib;libGLESv2.lib;

I have the following dlls in the path: Qt5Core.dll Qt5Gui.dll Qt5Widgets.dll Again (out of despair) added the following dlls to the path: qwindows.dll qminimal.dll libEGL.dll libGLESv2.dll

And I verified using dependancy walker that all of the dlls are 64 bit

This is the code:

void Bar(int argc, char* argv[])
{
    try {
        QApplication app(argc, argv);
    } catch (...) {
    }
}

And when I remark the main line

void Bar(int argc, char* argv[])
{
    try {
        //QApplication app(argc, argv);
    } catch (...) {
    }
}

I don't get any errors, and by errors I mean, of course, the application won't even start...

The main is:

int _tmain(int argc, _TCHAR* argv[])
{
    Bar(argc, reinterpret_cast< char ** >(argv));
}

Here is the error as displayed in the output:
'QtTest.exe' (Win32): Loaded 'C:\\workspace\\plugin\\TrdParty64\\Qt5Core.dll'. Module was built without symbols.
'QtTest.exe' (Win32): Unloaded 'C:\\workspace\\plugin\\TrdParty64\\Qt5Core.dll'

Answer 1

qwindows.dll (and qminimal.dll) need to be in platforms/ relative to your executable (or in your path)

Maybe that is the problem here?

Also make sure that all dll's are the right Qt version (for example 5.5.0 vs 5.5.1)
