Building Qt for Visual Studio 2010: Resolving Runtime Errors

The Challenge of Using Prebuilt Binaries

When attempting to utilize Qt with Visual Studio 2010, it's essential to note that prebuilt binaries designed for Visual Studio 2008 may not be compatible. This incompatibility often manifests as runtime errors.

The Solution: Building from Source

To overcome these issues, it's necessary to compile Qt directly from the source code. The steps involved are as follows:

1. Obtain the Qt Source Code:

   • Visit https://www.qt.io/download/ and download the "zip" file for Qt 4.8.6.
   • Extract the zip file to a location with a simple path, such as "E:Qt."

2. Open Visual Studio Command Prompt:

   • Launch the "Visual Studio Command Prompt (2010)" from the Start menu.

3. Configure Qt:

   • Navigate to the extracted Qt folder using DOS commands.

   • Run the following command to configure Qt with the appropriate flags:

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

4. Compile Qt:

   • Start the build process by typing:

     nmake

5. Set Environment Variables:

   • Set the following environment variables:

     • QTDIR: e:Qt (or the path to your Qt installation)
     • PATH: add the directory of Qtbin

6. Install Qt Visual Studio Add-in:

   • Download and install the Qt Visual Studio Add-in (qt-vs-addin-1.1.9.exe) from the Qt download page.

After following these steps, Qt and its demo applications should function correctly within Visual Studio 2010. Refer to the provided references for additional information and troubleshooting assistance.
