Embedded MATLAB C-code generation error

Hello all,

I am doing embedded C-Code generation using Embedded Matlab coder. I tried the Simulink Real-Time Workshop demo:

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

However after running:

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

I got the error:

??? Build error: Build failed for project "main_rtw". See the target build log for further details.

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

Compilation failed: Open error report.

The file main.c was generated. I am using Matlab R2008a and Visual C++ 2008 express edition. It should be mentioned that in order to configure Visual C++ 2008 express compiler with my 64 bit Matlab I used the following files:

Release 2009a is the first one that officially supports the Microsoft Visual C++ 2008 Express Edition on Windows 64bit for Embedded MATLAB: http://www.mathworks.com/support/compilers/release2009a/win64.html

So my recommendation would be use a newer MATLAB version so that the VC 2008 Express Edition is supported. In that case, please also have a look at note 6 on the page mentioned above.

Thanks Sebastian,

It should be mentioned that before configuring my Matlab using the files in following link:

http://www.mathworks.com/matlabcentral/fileexchange/22689

No installed compiler was located after running mex –setup.

However after doing what was mentioned in the readme file, the Visual C++ 2008 Express Edition was located successfully and mexopts.bat was updated.

Do you mean even if the Visual C++ 2008 Express is located by mex –setup, it does not work properly?

Thanks.

I don't know what exactly is done in the FileExchange solution that you mentioned. However, our developer have qualified and tested Embedded MATLAB only against the external C compiler listed on the page that I posted earlier. So if "mex -setup" did not show a compiler, then most likely because your compiler is not officially supported for that release of MATLAB.
