S function does not exist

Hi,

I have just installed a new library for SIMULINK called 'Aerosim Blockset' on Windows 10. After installing succesfully, when I try to run the model, it gives me the following error: * Error in S-function 'aerosonde_trim/Aerosonde UAV (Euler-angle kinematics)/Earth/WMM-2000/S-Function': S-Function 'sfunwmm' does not exist*. I have made sure that the file sfunwmm.c exists in the directory, as well as the files with extensions .def,.dsp,.dsw. I would appreciate any help!!!

Did you follow the installation instructions?

http://www.u-dynamics.com/aerosim/aerosim_install.pdf

Also, which MATLAB version are you using with your Windows 10 system? If you are not using R2015b then you might have a fair bit of difficulty getting a compiler to work.

[OLA ELHASSAN]

Thank you for your answer Walter.

Yes, I did. I also remembered to change the path for the block which needs the wmm.cof file. I am using R2014b.

When I installed Matlab, i got the following message:

1. The following products require a supported compiler: 
MATLAB Compiler 5.2 
MATLAB Builder NE 4.2.2 
MATLAB Builder JA 2.3.2 
Simulink Coder 8.7 
Simulink Real-Time 6.1
MATLAB Coder 2.7

So now, I just installed Windows 10 SDK since I read that "For the 64-bit Windows platform, a C compiler is not supplied with MATLAB." IF that doesn't work, I will try to download R2015b.

[Walter Roberson]

Windows 10 SDK will not work with R2014b.

[OLA ELHASSAN]

Yes, it didn't work, I will let you know if everything works after i finish installing R2015b and re-installing Aerosim.

[OLA ELHASSAN]

I have finished installing R2015b and reinstalling Aerosim but I still get the same error. Could it be due to this message I recieved after installing:

Your installation may require additional configuration steps.

1. The following products require a supported compiler:

• Simulink Coder 8.9
• Simulink Real-Time 6.3
• MATLAB Coder 3.0

2. MATLAB Compiler 6.1 requires a supported compiler for creation of Excel add-ins

3. MATLAB Compiler SDK 6.1 requires the following: * .NET framework for creation of .NET assemblies and deployable archives with Excel integration

• a supported compiler for creation of COM components, C and C++ Shared libraries
• a Java JDK for creation of Java packages

I meet am error when runing a demo, such as "S-Function 'sfunwmm' does not existn". I need your help, can we have a contact, my emil is [e-mail]

[Moh Ebah]

1, install the aerosim in program file, instead of program files(x86)

2, compile the sfunction using mingw as https://www.mathworks.com/matlabcentral/answers/335824-s-function-does-not-exist

3 add src folder to matlab path using pathtool It will be solved in sha Allah I tried in 18b 64bit

Answer 1

[OLA ELHASSAN]

I finally managed to get it to work by installing a 32 bit version of R2015b and then re-installing the Aerosim blockset. Everything is working, no more errors.

[Islam Elnady]

Hi Ola, Can we contact? I'm working on Aerosim Blockset and I might need your help. Kindly!

Thank you, Islam

I have the same error but in the (S-Function 'sfunflightgear092') i have tried to compile the cpp file of this function but it does not work

i would appreciate any help

[li zengyan]

You are right, the aerosim block can only run in the 32 bit version of matlab, because of the "dll" files
