  1. POQt 4.8.2 With GCC 4.7.0.1 Keeps Crashing
    text
    copied!<p>I've downloaded Qt 4.8.2 library, Qt Creator 2.5.2, and manually installed MingW with w32api version 3.13 and GCC/g++ version 4.7.0.1. My OS is Windows 7 Ultimate x64.</p> <p>I can create a sample "Plain C++ project" in Qt Creator; compile and run that console application using g++ without any issue.</p> <p>But I cannot <strong>run</strong> a Qt application. I used Qt Creator, created a dummy Qt Application using Creator's "Qt Gui Application" template. The project can be compiled successfully, without any error or warning. But the binary keeps crashing when I try to run (both from <code>Qt Creator</code> and <code>Windows Explorer</code>) it. Both debug and release builds crash. It crashes even before showing main window.</p> <p>MingW is installed in <code>C:\MingW</code> and <code>C:\MingW\bin</code> is in <code>PATH</code>. Qt is installed in <code>C:\Qt\4.8.2</code> and <code>C:\Qt\4.8.2\bin</code> is in <code>PATH</code>.</p> <p>I analyzed generated exe of the Qt Gui Application output with Dependency Walker and found that it found all required DLLs:</p> <ul> <li>c:\windows\system32\KERNEL32.DLL</li> <li>c:\windows\system32\MSVCRT.DLL</li> <li>c:\mingw\bin\LIBGCC_S_DW2-1.DLL</li> <li>c:\mingw\bin\LIBSTDC++-6.DLL</li> <li>c:\qt\4.8.2\bin\QTCORE4.DLL</li> <li>c:\qt\4.8.2\bin\QTGUI4.DLL</li> </ul> <p>So, what's causing the runtime crash?</p> <p><strong>EDIT</strong></p> <p>I also tried Qt's example projects: 2dpainting and addressbook - both crashed when they were launched.</p>
