Title: Making a WO Project dependent on a WO Framework Project
I'm having difficulty working out how to make an Xcode WO project depend upon a WO Framework project. Could anyone help?
I have a WO framework project and two application projects (a survey system and a booking system) that use the framework. Up until now, I've been developing and deploying the framework separately from the applications. The applications have the deployed framework added to their list of frameworks. This works fine. But I'm eager to make the application projects dependent upon the framework project to gain the debugging advantages of dependent projects.
In an attempt to establish this dependency, I've done the following:
1) I've placed a reference to the framework project in the application project using Xcode's Add to Project... menu option. This added an icon folder for the framework project into the Groups & Files of the application project. This icon folder contained references to the build products of the framework project.
2) I configured Xcode to use the same build location for all projects via the Building tab in the Preferences window. My understanding is that Xcode needs this to locate all of the build products during a dependent build.
3) I did the following to create the dependency (but perhaps this is where I'm going wrong). A WO application has three targets: an Application Server target, a Web Server target, and an aggregate target named after the project. The aggregate target has direct dependencies on the two other targets. I selected Get Info for the aggregate target, and in the Direct Dependencies list, add the framework projects aggregate target. I then dragged the framework's aggregate target above the the other two, so that it is the first dependency in the list.
When I build the application project, Xcode appears to build the framework without problems but produces numerous 'cannot find symbol' errors when it tries to compile the application. Examination of these errors indicates that Xcode is unable to locate the classes from the framework project.
I can make these errors go away by the following method, but I'm sure it's not the correct thing to do. In the application project, I've dragged the symbol for the framework's build products into the Compile Sources build phase of the application's Application Server target. This works fine for development - giving me the desired ability to debug both the application and framework together, but it doesn't work for deployment.
If anyone could pass on the last step to correctly wire up the dependency, that would be great.
I have ordered Chuck Hill's book - Beginning Xcode with WebObjects ... - but it won't arrive for another month (and of course, I don't know if it will address this issue).
Thanks
