Error when referencing a model

Hi,

When I am trying to run the basic model of referenced model (sldemo_mdlref_basic) I am getting below error.

>> sldemo_mdlref_basic

### Model reference SIM target (sldemo_mdlref_counter_msf.mexw64) for model sldemo_mdlref_counter is out of date because sldemo_mdlref_counter_msf.mexw64 does not exist
### Updating model reference SIM target for model: sldemo_mdlref_counter

'"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\Tools\..\..\VC\bin\vcvars64"' is not recognized as an internal or external command,

operable program or batch file.

'nmake' is not recognized as an internal or external command,
operable program or batch file.

The make command returned an error of 9009

'An_error_occurred_during_the_call_to_make' is not recognized as an internal or external command,
operable program or batch file.

### Real-Time Workshop build procedure for model: 'sldemo_mdlref_counter' aborted due to an error.

Please help me. I am using MATLAB R2010b.

Thanks

If you have not done so already, you need to install a recognized compiler. You can find the supported list at http://www.mathworks.com/support/sysreq/files/SystemRequirements-Release2010b_SupportedCompilers.pdf . It looks as if you might currently have a partial installation of VS 2010 Express; you might need to reinstall it.

Once you have installed the compiler, you need to use

mex -setup

to configure the compiler.

Once that is done, you should be able to load the model; it will need to recompile sldemo_mdlref_counter_msf for you automatically.

Hi Roberson,

Thanks for your reply.

I downloaded VS 2010 service pack 1 from Microsoft and installed it.

Then I run mex -setup which gives the below logs.

>> mex -setup

Please choose your compiler for building external interface (MEX) files:

Would you like mex to locate installed compilers [y]/n? y

Select a compiler:

[1] Microsoft Visual C++ 2010 Express in C:\Program Files (x86)\Microsoft Visual Studio 10.0

[0] None

Compiler: 1

Please verify your choices:

Compiler: Microsoft Visual C++ 2010 Express

Location: C:\Program Files (x86)\Microsoft Visual Studio 10.0

Are these correct [y]/n? y

Then after changing the current folder as "C:\Program Files\MATLAB\R2010b\toolbox\simulink\simdemos\simfeatures\", where the sldemo_mdlref_counter.mdl file is present, I run

>> mex sldemo_mdlref_counter.mdl

LINK : warning LNK4044: unrecognized option '/lkernel32'; ignored

LINK : fatal error LNK1104: cannot open file 'sldemo_mdlref_counter.mexw64'

??? Error using ==> mex at 208

Unable to complete successfully.

Therefore, I couldn't succeed yet to run the model.

Thanks Shambhu Sau

Do not mex the .mdl, just use

   sldemo_mdlref_basic

and it should build the .mexw64 for you.

Just to add with previous comment.

There is no such path or batch file as MATLAB looking for vcvars64 batch file during model reference update.

Only vcvars32.bat file is available at C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin

See http://stackoverflow.com/questions/1865069/how-to-compile-a-64-bit-application-using-visual-c-2010-express for additional steps you have to take to compile for 64 bits when you use the Visual C "Express" compilers.
