Linking frameworks might be easier when it comes to an update (as there's no need to track the version of the library, if it needs to change). Build system and integration libraries allows automatic building of GTK+-2 & 3 applications on OSX using the native Quartz display system, the Mac menubar, and familiar key bindings. The choice should be driven by the code maintenance tasks. There's no restriction so far NOT to use dynamic libraries. In many cases it's possible to load a dynamic library that resides within a framework structure at run-time, without needing to link the framework. The same approach as application bundles. If you see no LC_RPATH then none was specified.įrameworks themselves are simply special directory structures that contain a dynamic library, and possibly headers and other associated resources. At the end of the load commands list you should see an "LC_RPATH" entry (or entries): In order to see what RPATH was specified by the linker, simply run the otool -l myapp command. File formats may be either proprietary or free and may be either.

The file extension BUNDLE Apple Mac OS X Package File format specifies how bits are used to encode information in a digital storage medium. myappĭyld: Library not loaded: from: /Applications/MyApp.app/Contents/MacOS/./myapp A file extension format like BUNDLE Apple Mac OS X Package File is a standard way that information is encoded for storage in a computer file. The error log (or running from the command line) might reveal an error like MacOS %. If "rpath" was not specified, the application might fail to start. As a result will actually point to "Frameworks" folder of the bundle. For the macOS application bundle it would be the "MacOS" directory. rpath - is a special value that is recognized by the dynamic loader (see "man dyld") during the application load. This is done by specifying additional linker command: Thus the linker MUST BE given an instruction to specify the "Frameworks" folder as a runtime framework load path. However, such framework will need to be loaded in runtime. (for iOS the placement is similar, but different) The typical placement of a framework in macOS bundle is under "Frameworks" directory of "Contents": (NEVER distribute system frameworks with your application!)

Resources include library dependencies, such as third-party frameworks, which remove the need for the end user to have to install separately any needed third-party framework in their macOS system.
One of the beauties of the bundles system in macOS is that the application hides all of its necessary resources within a bundle. Many third-party libraries also come in the form of Frameworks for macOS (eg SDL) while providing an option to be loaded as a regular dynamic library.Ĭonfiguring search and rpath for frameworks in Lazarus All macOS system APIs come in the form of a framework. A special kind of Framework is a system Plugin (or driver).ĭistributing dynamic libraries as Frameworks is unique to macOS. The system loads the code and resources of a framework into memory, as needed, and shares the one copy of a resource among all applications. Because the library is dynamically shared, multiple applications can access the framework code and resources simultaneously. Your code accesses the capabilities of a framework through the application programming interface (API), which is published by the framework through its header files. When you develop an application, your project links to one or more frameworks.

After some reading, and digging into the Professional CMake book (thanks I now know how to get my Resources into the Bundle, and I think I linked my Framework correctly as well, but I cannot get it to be copied fully into the Framework folder, and I still have some issues with the executables.įor the resources, if anyone wonder, I’m using this snippet to keep the folder structure.See also: Multiplatform Programming GuideĪ framework is a bundle (a structured directory) that contains a dynamic shared library along with its associated resources, such as image files and header files.
