title: Receiving SIGABRT error when launching TTPhotoviewController in iPhone
body: <p>Well I'm creating an iPhone application which contains some features like Cycle routes and a Photoviewer.</p>
  
  <p>For these Cycle routes im useing the Cloudmade api, and for the PhotoViewer im useing Three20's TTPhotoviewcontroller.</p>
  
  <p>These Cycle routes map works perfect but i think it has todo something with the errors im getting.</p>
  
  <p>I will describe 2 cases down here about what I tried and what problem I received.</p>
  
  <p><strong>Case 1:</strong>
  Compiling goes wrong and receiving following error:</p>
  
  <pre><code>duplicate symbol _aatan2 in /Users/wesleycoppens/Documents/MooiWest/libs/Proj4/Device/libProj4.a(aasincos.o) and /Users/wesleycoppens/Documents/MooiWest/libs/route-me/Device/libMapView.a(aasincos.o)
  Command /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1
  </code></pre>
  
  <p>I am getting this error when i am trying to add to the Other linker flags the flag -all_load.
  See the image below here how my Other linker flags currently look like.</p>

  <p><strong>Case 2:</strong>
  Compiling goes fine, app runs in simulator perfectly but receiving SIGABRT with device.</p>
  
  <p>In this case I removed the flag -all_load in my Other linker flags. Now I am not receiving any compiling error, but I'm receiving a SIGABRT when tapping the tablerow which links to the photoviewer app.</p>
  
  <p>I aint sure if I do link correctly to the Photoviewer to, so here is the part where I push the other photoview.</p>
  
  <pre><code>PhotoTest2Controller *photoViewController = [[PhotoTest2Controller alloc] init];
  [self.navigationController pushViewController:photoViewController animated:YES];
  [photoViewController release];
  </code></pre>
  
  <p>Also here another screenshot of the linker flags how they are defined in this case:</p>
