[FLASH-USERS] undefined references in Simulation_init during linking

[Josef Stöckl]

Hi Ken,

Did you check your dependencies in the Makefile? This looks like you haven't
specified the module dependencies, so the FLASH setup script doesn't know
that you need the Simulation_data module for linking. Please check, if you
have something like the following two lines in the Makefile within your
simulation's directory (source/Simulation/SimulationMain/<simulation
name>/Makefile):

Simulation += Simulation_data.o 
Simulation_init.o : Simulation_data.o

I hope this helps. After modifying the Makefile you need to call the FLASH
setup script again, so that the proper build environment gets reworked.

Best regards,
Josef
