Qt application deployment mac os x

We can also add plugins extending Qt, for example adding SQL drivers or image formats. We just need to follow the directory structure outlined in plugin documentation, and make sure they are included in the QCoreApplication::libraryPaths. Let's quickly do this with the image formats, following the approach from above. After constructing the QApplication , we add the following code:. First, we tell the application to only look for plugins in this directory.

In our case, this is what we want since we only want to look for the plugins that we distribute with the bundle.

Now you should be able to move the application to another Mac OS X machine and run it without Qt installed. Alternatively, you can move your frameworks that live outside of the bundle to another directory and see if the application still runs. If you store the frameworks in another location than in the bundle, the technique of linking your application is similar; you must make sure that the application and the frameworks agree where to be looking for the Qt libraries as well as the plugins.

When you are done linking your application to Qt, either statically or as frameworks, the application is ready to be distributed. Apple provides a fair bit of information about how to do this and instead of repeating it here, we recommend that you consult their software delivery documentation. Although the process of deploying an application do have some pitfalls, once you know the various issues you can easily create packages that all your Mac OS X users will enjoy.

Using Qt's Mac deployment tool

Be sure to distribute any Qt plugins that you need with your application, and note that each type of plugin should be located within a specific subdirectory such as imageformats or sqldrivers within your distribution directory, as described below. The search path for Qt plugins as well as a few other paths is hard-coded into the QtCore library. But using pre-determined paths has certain disadvantages. For example, they may not exist on the target machine. For that reason you need to examine various alternatives to make sure that the Qt plugins are found:.

The How to Create Qt Plugins document outlines the issues you need to pay attention to when building and deploying plugins for Qt applications. You can check which libraries your application is linking against by using the otool tool. To use otool , all you need to do is to run it like this:. Unlike the deployment processes on X11 and Windows , compiler specific libraries rarely have to be redistributed along with your application. But since Qt can be configured, built, and installed in several ways on Mac OS X, there are also several ways to deploy applications.

Typically your goals help determine how you are going to deploy the application. The last sections describe a couple of things to keep in mind when you are deploying your application. From Qt 4. This is achieved using weak linking.

In weak linking , Qt tests whether a function added in a newer version of Mac OS X is available on the computer it is running on. This allows Qt to use newer features, when it runs on a newer version of OS X, while remaining compatible on the older versions. You can add:.

This is accomplished by passing -universal on the configure line of the source package, and requires that you use GCC 4. For example:. This is beyond the scope of this document and is not something we have tried, but Apple documents it on their developer website. Once you have a universal Qt, qmake will generate makefiles that will build for its host architecture by default.

Deploying native apps to macOS

Besides lipo , you can also check your binaries with the file 1 command line tool or the Finder. It is designed to automate the process of creating a deployable application bundle that contains the Qt libraries as private frameworks. Note: If you want a 3rd party library to be included in your application bundle, then you must copy the library into the bundle manually, after the bundle is created. As an additional note, I wrote my application by using the Qt framework.

As a side comment, I also found a CLI utility that will setup your application bundle for you. It's called "macdeployqt" and it can be found in the "bin" folder in the path where you installed Qt.

I came up with this problem last week and I got my information from this source: You can check what other libraries your application links to using the otool: otool -L plugandpaint. I don't take credit for this answer, I'm just a pointer to the source of information.

Qt is a free and open-source widget toolkit for creating graphical user interfaces as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems with little or no change in the underlying codebase while still being a native application with native capabilities and speed. Mac OS Just run it from terminal using this command: Qt is a comprehensive application and UI framework for developing Mac applications that can also be deployed across many other desktop and embedded operating systems without rewriting the source code.

So I'm trying to deploy the plug-in onto a mac that doesn't already have the Qt framework installed, but with no success so far. Note that all those configurations are made on and for a PPC target. It has a rich history in the Linux world, is widely used in embedded devices, and has made great strides in the Mobile arena over the past few years. Write your source code once, build and watch it run on any operating system and hardware. Download Qt. This process is described in detail in the Debugging Techniques document.
