Undefined reference error while deploying Simulink model

Getting Undefined reference error while deploying a tgz file of Simulink Model. The tgz file is generated for ROS catkin workspace and no errors while generating the file. While deploying, the error is generated. By adding the header file which contains the missing variables in generated C++ code, error is cleared. But it is a kind of manual work whcih need to check all the missing variables in each file.

Please help in resolving the issue.

Could you elaborate the 'undefined reference' error more details? The catkin_make was not able to resolve the reference to a library?
