Using a third-party library with Qt is a simple process. Suppose you know of a cross-platform library that accepts audio samples of a cat's meows and translates them into English words. This library is named CatWhisperer , and has several files that it provides as part of its library. Your project, MyQtApp , stores these files in a folder named 3rdparty :. Optionally, you can also:. The information above is provided in the.

This tutorial illustrates different approaches for using a custom library in your application on Windows. The first part explains how to create a shared library and how to link against it in your application. The second part is about creating and using a static library. When creating a shared library that you would like to link against, then you need to ensure that the symbols that are going to be used outside the library are properly exported when the library is created. Subsequently imported when you are linking against the library. On Windows, MinGW will output. They are needed to link your code against the library. See also the documentation on Creating Shared Libraries. Also you need to link against the import library file. At runtime this loads the shared library. To set this up, you have to modify your application's. You need to inform qmake where to find the headers and the library. QLibrary can be used for loading shared libraries at runtime. In this case you only need access to the.

In addition to Qt libraries, you can add other libraries to your projects. The process depends on the type and location of the library:. Qt Creator supports code completion and syntax highlighting for the added libraries once your project successfully builds and links to them. The library can be located either in the build tree of the current project or in another build tree. Because system libraries do not typically change and are often found by default, you do not need to specify the path to the library or to its includes when you add it. You can use pkg-config to query system libraries during compilation. For your own libraries and 3rd party libraries, you need to specify the paths. Qt Creator tries to guess the include path for an external library, but you need to check it and modify it if necessary. Qt Creator automatically adds the include path for an internal library.
