How to Troubleshoot Qt Integration Issues with Visual Studio 2010?

Troubleshooting Visual Studio 2010 Qt Setup

While integrating Qt with Visual Studio 2010, you may encounter issues using prebuilt binaries. This article provides a comprehensive guide to resolve such problems and build Qt from source for optimal compatibility.

Why Prebuilt Binaries Fail

Precompiled binaries designed for Visual Studio 2008 may not work with Visual Studio 2010. They often lead to runtime errors due to a dependency on the DebugCRT available only with Visual Studio 2008.

Downloading Qt

To address this, it's crucial to download the source code from Qt's website. Extract the zipped file into a convenient folder.

Building Qt

Open the Visual Studio Command Prompt to configure Qt using the appropriate flags. For a minimalist build, consider the following command:

configure.exe -release -no-webkit -no-phonon -no-phonon-backend -no-script -no-scripttools -no-qt3support -no-multimedia -no-ltcg

Once configuration is complete, execute the build process with:

nmake

Setting Environment Variables

Set environmental variables (QTDIR and PATH) to inform programs about the Qt location. Use setx or Control Panel to adjust these variables.

Qt Visual Studio Add-in

Install the Visual Studio Add-in for seamless integration after logging off and back on. Qt demo applications should now run correctly.

Appendix A: Official Instructions

Refer to Qt's official wiki for additional information, but note that it may not provide sufficient details for Visual Studio 2010 integration.
