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. Makefiles contain all the information needed by your compiler and linker to produce output, whether it is an executable, another library file, etc.

Add library qt

You have to add the include path, the libraries and if you are aiming to have a cross-platform project, you need to account for Windows, macOS and Linux operating systems separately. As you can see above, there are a number of additional options you can choose. In fact you can keep this snippet and simply paste it into your projects in order to add OpenCV to your library. Obviously, you can do the same for any other library. This is the second method of adding libraries to Qt projects. The second method that was just mentioned, can be further improved by copying and pasting all the lines from the snippet above into a text file with the PRI extension and including it in the project using the include function. Here is an example:. I hope it makes sense. Thank you for the info. But please, what I have to do to include a reference to this library in my source code? Your email address will not be published.

The settings depend on the library type. Qt Code: Switch view. In addition to Qt libraries, you can add other libraries to your projects.

The command is defined in the Core component of the Qt6 package, which can be loaded like so:. It supports the same set of arguments as this command. It performs the following tasks:. If none of these keywords are given, the library type created depends on how Qt was built. If Qt was built statically, a static library will be created. Otherwise, a shared library will be created. After a target is created, further processing or finalization steps may be needed.

Add library qt

The following sections list certain things that should be taken into account when creating shared libraries. Symbols - functions, variables or classes - contained in shared libraries intended to be used by clients , such as applications or other libraries, must be marked in a special way. These symbols are called public symbols that are exported or made publicly visible.

Loading Comments First post. Static linking results in a stand-alone executable. For more information about the project file settings, see qmake Manual: Declaring Other Libraries. This is the second method of adding libraries to Qt projects. Specify settings for the library. Linking Specify whether the library is statically or dynamically linked. Through external libraries, Qt Creator can support code completion and syntax highlighting as if the code were a part of the current project or the Qt library. Re: How to add a lib to a qt project Thanks for your reply. If Qt was built statically, a static library will be created.

Qt empowers productivity across the entire product development lifecycle, from UI design and software development to quality assurance and deployment. Find the solution that best suits your needs. Stay informed about our live events and webinars, whether they're online, in person, or face-to-face.

For example, on macOS, it detects the library type Library or Framework automatically and hides the option. Re: How to add a lib to a qt project. Re: How to add a lib to a qt project So it looks like you'll need to build it indeed - its quite easy, just follow the link ChrisW67 gave you in previous post there is QPSQL section. Qt Creator automatically adds the include path for an internal library. Bookmarks Bookmarks Digg del. The library can be located either in the build tree of the current project or in another build tree. Are they linker errors or compiler errors? How To Add libraries to qmake projects In addition to Qt libraries, you can add other libraries to your projects. They are needed to link your code against the library. I think I need more information, about what I have to do.
