We are developing an application for iphone 4 in xcode4 where we get an error when compiling for the device:

{standard input}: unknown: Undefined local symbol LC85
{standard input}: unknown: Undefined local symbol LC86
Command / Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1

We are using the gcc 4.2 and Eigen packages such as SVD, Array, QR, LU, Core, Cholesky, etc.
However when compiling for the iPhone Simulator 4 gives no error.

As could be solved?
