I'm experimenting with a simple hello world function to see how the coder works.

disp('Hello world')

The mex version works, but when I make a standalone executable there is no output. In fact, the generated code for the function itself is completely empty ({}), like the disp() was purposely skipped over. Is this the expected behavior, or is there some setting I can change?

EDIT: I just tried fprintf(1,'Hello world'), and the converted code contains "cfprintf()". So still, purposely suppressing output? BTW, this is on Linux/2016b.

Is there a recommended workaround for the problem of wanting to generate console output from an M file that is generated to C/C++ code?

The 'disp' function is not supported to generate C/C++ code from MATLAB code. You can refer to the following documentation link for a list of functions that support code generation:
