OS X dlopen can't find framework - Image Not Found

Question

I'm trying to add Google Breakpad (some external framework) support to my application. I have done all the required steps, but when I try to load my application using dlopen, I get this error:

(char *) error = 0x0000000100200175 "dlopen(/Users/user/MyApp.app/Contents/MacOS/MyApp, 1): 
Library not loaded: @executable_path/../Frameworks/Breakpad.framework/Versions/A/Breakpad\n  
Referenced from: /Users/user/MyApp.app/Contents/MacOS/MyApp\n  
Reason: image not found"

I checked and the Breakpad file does indeed exist in the relative path (to the MyApp file).

Here's the otool -L on the MyApp file (notice the @executable_path):

Users-Mac:MacOS user$ otool -L MyApp

Anyone has a clue?

How have you built MyApp and included the framework? and why and how used dlopen? — mmmmmm, Sep 07 '14 at 20:34
I included the framework. It is added to the Frameworks folder and to a Copy Files stage that copies it into Frameworks. Also, I can find it in /Contents/Frameworks/Breakpad.framework — Tsury, Sep 07 '14 at 20:40
I am using dlopen because my application has a wrapper that loads it. — Tsury, Sep 07 '14 at 20:40

Follow this steps, It may work:

go to Target then press Build Phase
left top of this page you will find + symbol, press this symbol.
press New Copy Files Build Phase
expand copy file then Drag you framework and drop in this section.
Change the Destination to frameworks

Hope it will Work

I already stated that I added a Copy Files phase to copy the framework. – Tsury Sep 08 '14 at 11:41

Well, it turns out it was a problem when using dynamic libraries and compiling for OS X 10.6. The @executable_path doesn't get updated after the dynamic load and thus the LOADED binary is looking for its dependencies relative to the LOADING binary.

I ended up recompiling my framework, Breakpad, and using @loader_path instead of @executable_path, and now everything works just fine.
