MATLAB: How to use the C code generated from Real time Workshop in Visual Studio

matlab to visual studioreal time workshop c codesimulink coder

I have created a very simple add model which takes two constants and returns their sum. Then I generated the C code using Real Time Workshop with grt.tlc as the target by referring to the following link "http://blogs.abo.fi/alexeevpetr/2011/11/18/simplified-building-simulink-generated-c-code-in-visual-studio/ ". I now want to use this code in Visual Studio 2010. But i have more than 300 errors popping up. I followed the approach specified in the link " http://blogs.abo.fi/alexeevpetr/2011/09/30/building-simulink-generated-c-code-in-visual-studio/" But the problem is that i do not have MATLAB installed in the system where the Visual Studio is present. I have however got the .h and .c files required which are mentioned in the link above.I am also new to Visual Studio. Please provide the solution in step wise procedure, so that i can follow it easily.

I think the easiest way is to select the System target file (in the Configuration Parameters window's Code Generation pane) that corresponds to "Create Visual C/C++ solution file" - this should create a Visual Studio project (solution file) that you can directly load into Visual Studio. Alternatively, see Relocate Code to Another Development Environment.

MATLAB: Do I receive unresolved external symbol errors when building the project in MSVC Development Studio after creating the code using Real-Time Workshop 5.1 (R13SP1)

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

This is a bug in Real-Time Workshop 5.1 (R13SP1) occurring due to the exclusion of particular source files. Our development staff is investigating this issue.

One possible workaround is to delete the $MATLAB\toolbox\rtw\dspblks\c\dspsqdesign directory from your R13SP1 install tree. This should prevent the files in it from being included in the [model].mak file.

Please note this workaround has not been verified yet.

MATLAB: How to set up MATLAB Visual Add-in in a Microsoft Visual C/C++ environment

The MATLAB Add-in for Visual Studio has been obsoleted as of the release of MATLAB 7.0 (R14). If you are using a previous release of MATLAB, read the following:

MathWorks provides a MATLAB Add-in for the Visual Studio development system that lets you work easily within Microsoft Visual C/C++ (MSVC). Note that MATLAB Add-in is not compatible with Microsoft Visual Studio .Net or the versions of Microsoft Visual C/C++ later than 5.0 or 6.0.

The MATLAB Add-in for Visual Studio greatly simplifies using MATLAB files in the MSVC environment. The Add-in automates the integration of MATLAB files into Visual C++ projects. It is fully integrated with the MSVC environment.

The Add-in for Visual Studio is automatically installed on your system when you run either mbuild -setup or mex -setup and select Microsoft Visual C/C++ version 5 or 6. However, there are several steps you must follow in order to use the Add-in:

1. To build MEX-files with the Add-in for Visual Studio, run the following command at the MATLAB command prompt.

       mex -setup

Follow the menus and choose either Microsoft Visual C/C++ 5.0 or 6.0. This configures Mex to use the selected Microsoft compiler and also installs the necessary Add-in files in your Microsoft Visual C/C++ directories.

2. To build stand-alone applications with the MATLAB Add-in for Visual Studio (requires the MATLAB Compiler and the MATLAB C/C++ Math Libraries), run the following command at the MATLAB command prompt.

       mbuild -setup

Follow the menus and choose either Microsoft Visual C/C++ 5.0 or 6.0. This configures mbuild to use the selected Microsoft compiler and also installs the necessary add-in files into your Microsoft Visual C/C++ directories. (It is not a problem if these overlap with the files installed by the mex -setup

command.)

3. For either Mex or stand-alone support, you should also run the following commands at the MATLAB prompt.

cd(prefdir); mccsavepath;

These commands save your current MATLAB path to a file named mccpath in your user preferences directory. (Type prefdir to see the name of your user preferences directory.)

NOTE: This step is necessary because the MATLAB Add-in for Visual Studio runs outside of the MATLAB environment, so it would have no way to determine your MATLAB path. If you add directories to your MATLAB path and want them to be visible to the MATLAB Add-in, rerun the cd and mccsavepath commands shown in this step and replace prefdir with the desired pathname.

4. To configure the MATLAB Add-in for Visual Studio to work with Microsoft Visual C/C++:

a. Select Tools -> Customize from the MSVC menu.

b. Click on the Add-ins and Macro Files tab.

c. Check MATLAB for Visual Studio on the Add-ins and Macro Files list and click Close. The floating MATLAB Add-in for Visual Studio toolbar appears. The checkmark directs MSVC to automatically load the add-in when you start MSVC again.

Note: To run the MATLAB Add-in for Visual Studio on Windows 95 or Windows 98 systems, add this line to your config.sys file.

shell=c:\command.com /e:32768 /p

Note: If you are using Windows ME, refer to the related solution listed below:

For additional information on the MATLAB Add-in for Visual Studio:

- See the MATLABAddin.hlp file in the matlabroot\bin\win32 directory where 'matlabroot' is the output of the MATLAB command prompt when 'matlabroot' is executed, or

- Click on the Help icon in the MATLAB add-in for Visual Studio toolbar
