Sparrow xcodeproj Reference Linker Errors

christian-alexander

I just broke my project by deleting sparrow.xcodeproj from the file/folder structure in the left window pane in xcode.

I was trying to re-add the sparrow reference in such a way that I would be able to view the sparrow source from within my project by just clicking the arrow on the sparrow.xcodeproj to expand it.

When I left clicked and selected "add files to scaffold" it added the xcodeproj file but I now get a million linker errors. So it seems as though xcode is no longer able to find the sparrow source.

I also had the SPARROW_SRC tree variable set up according to the directions on the sparrow website.

So here are my questions:

Why does the sparrow.xcodeproj in the demo project have an arrow to expand & display all of the source files but the sparrow.xcodeproj in the scaffold project does not?
Why am I getting these linker errors when I re-add the sparrow source?
(I guess maybe I just need to understand how to properly add frameworks & dependencies in xcode)

I really liked the idea of using the source tree variable to reference sparrow but it has caused a lot of headaches for me. My project broke when I had to move to another computer then I had even more problems updating to sparrow 2.0. I am so sick of having to troubleshoot these linker errors that I am considering just incorporating all of my source code into the demo project and keeping everything contained in one project.

Any help is appreciated!

Any luck? After years of iOS development, I still run into unknown build and linker errors which could be due to various different reasons.

One of the most common problems is not linking the library to the project target. Make sure you add "Sparrow" in "Target Dependencies", and add "libSparrow.a" in "Link Binary with Libraries". You also need to make sure to link all the libraries that Sparrow depends on.

Alternatively, you can link "Sparrow.framework" instead of the Sparrow project, but I won't discuss that in this post.

Reference:

If this doesn't fix your problem, please post the error log.

You can avoid the source tree route by using "Sparrow.framework" or adding the "Sparrow.xcodeproj" root directory as a sub-directory to your actual project.
