qtchooser: command not found

qtchooser is a command-line tool that serves as a wrapper to select between different versions of the Qt development binary. Qt is a widely-used cross-platform development framework used to create graphical user interfaces (GUIs) and other applications.

qtchooser is particularly useful when you have multiple versions of Qt installed on your system and need to select the appropriate version for your project. By default, Qt installs its binaries with version numbers appended to the file names, which can make it difficult to maintain and switch between different versions of the framework.

qtchooser simplifies this process by providing a standardized way of selecting between different Qt versions. The tool uses a set of rules to determine which version of Qt to use based on the project requirements and the available versions of Qt on the system.

If you encounter the below error while running the command qtchooser:

Summary

qtchooser is often used in combination with other Qt tools such as qmake, qbs, and cmake. By selecting the appropriate version of Qt with qtchooser, you can ensure that your project uses the correct version of the Qt libraries and tools, regardless of which versions are installed on the system.

Overall, qtchooser is a valuable tool for managing multiple versions of the Qt development binary and simplifying the process of selecting the appropriate version for your project.
