C++ S-function in Real-Time Windows Target

Hello to all,

I have written a C++ S-function to be used on HIL. To test it firts, I have used the counter C++ S-function example (sfcndemo_counter_cpp).

It works and compile to Real-Time Windows Target properly, but when I want to connect to target (RT Windows target) the following erros appears:

Error occurred while executing External Mode MEX-file 'rtwinext': Error loading real-time executable: undefined symbol "_Znwy"

Does Real-Time Windows target work with C++ S-function?

I am using Matlab R2013b, Windws 7 64-bits.

Thank you in advance

Hello Ruben Marti,

I am also struggling with the same problem. Did you find any workaround for the problem??

Thanks, Vamsi.

The problem is in line 131 and 187 of sfun_counter_cpp.cpp - the new/delete commands are not supported in real-time code generation. You will need to replace those with malloc/free.
