Under System Variables, scroll down and find the Path variable, then click Edit. Click New and enter the path to the MinGW bin folder (e.g., C:\MinGW\bin).

Configuring Qt Creator

Now that you have MinGW set up, it's time to configure Qt Creator:

  1. Open Qt Creator: Launch Qt Creator from your Start menu or by searching for it in the Windows search bar.
  2. Create a new project: Click on File > New File or Project, then select Application under the Projects tab.
  3. Select MinGW: In the project settings, select MinGW as your compiler.
  4. Configure the compiler: In the compiler settings, make sure the path to the MinGW bin folder is correct.

Compiling Your Library

Now that you have Qt Creator set up, it's time to compile your library:

  1. Create a new project: Click on File > New File or Project, then select Library under the Projects tab.
  2. Select MinGW: In the project settings, select MinGW as your compiler.
  3. Configure the compiler: In the compiler settings, make sure the path to the MinGW bin folder is correct.
  4. Compile your library: Click on the Build button or press F7 to compile your library.

Common Errors and Solutions

When compiling your library, you may encounter common errors. Here are some solutions to help you overcome them:
