Converting Simulink file (.slx) to .dll for integrating with CANoe

I am trying to generate a .dll file from a simulink model to integrate with Vector CANoe.

I have chosen 'cn.tlc' in the code generation panel. I have set my environment variables to point to the mingw64 binaries.

I have used 'getenv' to check if matlab points to the same folder. But when I try to build the model, I get the following error:

C:\Users\prade\Desktop\Work\Attempts\CON_veh\Simulator\MCU_cn_rtw>call "set MINGW_ROOT_PATH=C:\MinGW\mingw64" x86 The filename, directory name, or volume label syntax is incorrect.

I am on a Windows 10 64 bit OS.

hey,

At the moment I'm writing my bachelor thesis on this topic and I have exactly the same problem. If you have solved it, I would be very happy if you tell me what you did.

many Greetings

Hi,

I have the same problem . Have you found the solution ?

[Nouran Mostafa]

I 'm trying the same generting DLL from simulink model by Configuring Microsoft Visual C++ 2015 as a C/C++ compiler.

I have chosen 'cn.tlc' in the code generation panel.I was able to compile successfully but no DLL obtained

I don't have any errors but no dll either.

@Stefanie Schwarz@Felix Bleimund

are there any other required congiuration to obtain the DLL ?

[Stefanie Schwarz]

@Nouran Mostafa Please contact Vector for support regarding cn.tlc: https://www.vector.com/int/en/support-downloads/support/

Hello, is doable by this tutorial https://cdn.vector.com/cms/content/know-how/_application-notes/AN-IND-1-007_Using_MATLAB_with_CANoe.pdf

In general, please contact Vector for questions regarding their cn.tlc target:

https://www.vector.com/int/en/support-downloads/support/

From our experience, the issue can be resolved as follows:

1) Consult the Vector CANoe User Manual to determine which compiler is supported with cn.tlc. As far as we know, MinGW is currently not supported and you need to install a specific Visual Studio C++ version.

2) Make sure to install Visual Studio with the "Desktop development with C++" workload as described here:

https://www.mathworks.com/matlabcentral/answers/443349-how-do-i-install-visual-studio-2017-or-2019-for-use-with-matlab-simulink

3) Run the command

>> mex -setup c++

in MATLAB to select the supported Visual Studio compiler after installing it.

4) Make sure that you have selected C++ as Language in the model settings under Configuration Parameters > Code Generation.

After fighting for days with inlcude directories and environment variables I stumbled over your answer.

Just configure the mex compiler for c++ and NOT c and it works! Thank you!

[Stefanie Schwarz]

Thanks for the feedback, I'm glad I could help!

[Louisa Lohn]

I stumbeld over your answer because I have a similar problem.

I tried to run the command "mex -setup c++" but it doesn't work. I only get the following feedback: "Error using mex. Supported compiler not detected. You can install the freely available MinGW-w64 C/C++ compiler; see Install MinGW-w64 Compiler. For more options, visit https://www.mathworks.com/support/compilers."

Can you help me how to get the command executed?

[Stefanie Schwarz]

Hi @Louisa Lohn, you executed the command correctly, but it appears that you either didn't install Visual Studio, or that Visual Studio is not detected by MATLAB. Please submit a help request to MathWorks and attach the output that you receive after executing: >> mex -setup -v

Update 2024: According to the video tutorial below, the CANoe target now supports MinGW as compiler:

https://www.youtube.com/watch?v=hVfaM_f_rO8

In this case, you need to make sure to select the matching template makefile (.tmf) for MinGW in the model's code generation settings. For details, please refer to the "Vector CANoe Matlab Integration Package" documentation, or Vector technical support.
