I am trying to cross compile in eclipse using the arm gcc compiler. I go to projrct , properties and set the c/c++ compile option and set the flag to -mfloat-abi=hard. It throws the following exception while building:
**** Build of configuration Debug for project HelloWorld ****

It builds fine without that flag. But I need to set it for it to run on the beaglebone.Any ideas what I am doing wrong?
Output after using -print-multi-lib
