We have a very rare problem.
In some machines we have installed the last version of xcode4 and works fine.
We can chose in "C/C++ Compiler Version"
between GCC or LLVM, but in other machines with the same xcode4, we don't have "C/C++ Compiler Version" option, only GCC_VERSION, and obviously, we cant chose between LLVM or LLVM-GCC. The arrows don't appear.
We don't have any idea why the arrows don't appear in some machines, and it works great on other machines.
Any ideas??
Thanks.
