MATLAB: Emlc error in converting M-code to C-code

Hi,

I am going to convert an M-code to C-code.

I started with the Simulink Real-Time Workshop demo i.e.:

Demos>Simulink > Real-Time Workshop > Application Samples > Embeddable C-Code Generation Using Embedded MATLAB Coder

For compiling the M-File into an executable file I tried exactly what the demo says, i.e.:

emlc -T rtw:exe -o rtwdemo_emlcsobel rtwdemo_emlcmain.m stdio.h

It should be mentioned that the file main.c was generated, however I got this error:

??? Unknown compiler

Error in ==> main Line: 1 Column: 1

Compilation failed: Open error report.

??? Error using ==> emlc

It seems that the compiled algorithm is not generated. I have the license for real-time_workshop.

Any idea?

Many thanks
