Hello,

I have a problem by running a model (OpenLoop.mdl) with S-funtion in simulink external mode. This error appears:

gmake: * No rule to make target `SFunc.obj', needed by `../OpenLoop.rxw64'. Stop. ### Build procedure for model: 'OpenLoop' aborted due to an error. Error(s) encountered while building model "OpenLoop"

Please, has someone an idea? Thank you

Hi David,

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:

Incorrect Path: Your project path, source file path and/or include folder path contains white spaces that the "make" tool cannot handle.
Missing File: It could also mean that the indicated file is missing.
Windows Character Length Limit: A long directory path name could also violate the Windows 256-character length limit and result in this error.
Simulink Real-Time Character Length Limit: The error could be due to the third-party QNX compiler used by Speedgoat hitting the character length limit

Please refer to the following MATLAB Answer post for more detail:

I hope this helps!
