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
Arza

You need to get one of the supported compilers and then run mex -setup: http://www.mathworks.com/support/compilers/release2008a/

Which C compiler do you have installed and configured for this use, and which Matlab version are you using?

I am using Matlab R2008a (Ver. 7.6.0.324) and I have Microsoft Visual C++ 2010 Express (Ver. 10.0.30319) installed.
I tried to set up the C compiler by running:
mex –setup
However, after letting mex to locate installed compilers, it shows None. (It does not show the installed visual C++)

You need to have appropriate mexopts files for each compiler so that mex -setup knows about it. e.g., for MSVC 2010 Express you would need msvc100freeopts.bat and msvc100freeopts.stp in the [matlabroot '\bin\win32\mexopts'] directory
