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

Arza

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

Answer 2

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

Answer 3

[Arza]

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++)

[James Tursa]

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
