I'm using the latest version of opencv (opencv 2.4.9) and I have to have the -ObjC flag, required by Core Plot (a plotting framework).
When I set -ObjC in the other flags, I get a lot of errors (28 actually) of type : Undefined symbols for architecture i386
as follow :
Undefined symbols for architecture i386:

... etc
It is the same problem as Bartosz Bialecki, I tried the proposed solution but problem's still here.
Does anyone have an idea ?
Here are all the framework I included :
Problem solved adding several frameworks :
CoreVideo.framework
, AssetsLibrary.framework
, CoreMedia.framework
.
Here is the complete list of the included frameworks :
