How to solve the "No rule to make target `.refresh', needed by `ert_main.o.opt'. Stop." when I use Embeded Coder to build generated C code?

Hi,

When I try to use RTW demo to build the model with Embeded Coder it appears this error. Could you tell me where the fault is? Thanks!

Hi,

The error "No rule to make target" is typically thrown by the make/gmake build automation tool because it can't find the instructions on how to create a particular file or target. This can happen for several reasons.

Please refer the following MATLAB Answer to understand more about this issue and approaches adopted to resolve this issue:
