build model for stm32f4 discovery get error

 hi ! thank for hearing to me 
 this is my issue , i am try to use stm32f4 discovery package to generate and build code ... i started from tourial of matlab here <http://www.mathworks.com/help/supportpkg/stmicroelectronicsstm32f4discovery/examples/getting-started-with-embedded-coder-support-package-for-stmicroelectronics-stm32f4-discovery-board.html my tutortial> , after install this package with successfuly  , i open led model example and setup step by step like following  guide .... and the erro occur when i buld code ..
here is my diagnostic viewer
