Xcode linker error in iPhone application (simulator only)

Question

I get this linker error that will not allow me to compile. This only happens on the simulator.

KEY POINTS:
- It only happens in the simulator
- Similar to THIS question , but did not find FRAMEWORK_SEARCH_PATHS in my .pbxproj file
- Although my OS is 10.6.2, I had to create a goal of 1.5 to avoid other linker errors.
- libxml2.dylib IS is required and is in my Frameworks group
- Other cited libraries that I have never heard of.
- The attempt to attract other Lieb within the framework did not resolve.

CLUE:
Again, my question is very similar to THIS RESOLVED QUESTION , except that in my case I did NOT find the FRAMEWORK_SEARCH_PATHS entry in the .pbxproj file in my project package and therefore could not decide how this issue was resolved.

Answer 1

The problem is this:

 -L/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk/usr/lib 

This suggests that your Simulator (i386) is going to use files from the device (arm) / usr / lib.

Find your target where / usr / lib (just use the search bubble on the “Get Info / Settings” tab) and delete it. The compiler will use the correct usr / lib platform if it does not use the wrong one at first.

Answer 2

I have the same problem. And it turns out that my release version code is running in a debugging environment. Click "Edit Schema ..." and change the "Assembly Configuration" to solve the problem.

Answer 3

The same thing happened to you. I uninstalled and added all my frameworks and still had the same problem. To get rid of the error, I had to remove the path pointing to the intruder library from the library search paths in the build settings.
