Truncated Fat File Linker Error

Question

Although I am familiar to developing in Objective-C, I still consider myself a bit of a n00b when it comes to error interpretation. I working on an application for work that others are also working on. I believe we may have different versions of Xcode, and one developer has a PC (the others and I have a MacBook). I am using Xcode 4.5.1.

The Problem

I am getting the following Apple Mach-O Linker Error:

ld: truncated fat file. Slice from 68 to 2783300 is past end of file with length 135 for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)

The full error is as follows (paths renamed):

I have found close to no documentation on this error. What's the problem? How do I resolve an error like this?

Answer 1

I read this answer somewhere,

Symbolic links to files and folders (in your case some framework) are turned into fat files when they are moved from MAC-OS/X to Windows. So whenever we copy-paste/checkout project frameworks from your MAC to windows or vice versa it gets changed, the files are modified in terms of symlinks.

So what you can do is just checkout your project files and replace the framework alone (please note the framework you are going to replace should be downloaded fresh or copied somewhere from a MAC , NOT WINDOWS).

Hope this helps someone!
