Question

I’m having trouble adding a static library from another Xcode project (CloudApp API) to my Xcode project. My project has two targets — a prefpane bundle, and a console application. I want to add the static library to the console application. Here’s what I’ve done so far:

• Created a new workspace
• Added the CloudApp project to my workspace
• Added the libcloud.a file to my “Link Project Binaries” list for the target binary
• Added -ObjC to the “Other Linker Flags” setting for the target binary
• Added $(BUILD_PRODUCTS_DIR) to the “User Header Search Paths” setting for the target binary
• Copied all the relevant headers from the CloudApp project into my project (without adding them to the target) so that I don’t get errors from any #import statements
• Edited the scheme for the target binary to require compiling CloudApp first
• Added relevant frameworks to the target (Cocoa, Foundation, CoreFoundation)

Doing all this worked fine when I just had a single Cocoa target (not a console application). But now I’m getting errors in the CloudApp header files I included. Basically things like this:

In CLWebItem.h:
Unknown type name 'NSImage'

Any ideas?

Create a prefix-header.pch and #import <Cocoa/Cocoa.h> inside. Make sure to compile the prefix header in your settings.
