'C Caller block is not recognizing the c program

Eventhough i have specified the header and c file in the c caller block the simulink gives an erreoe as follows:

''C Caller block 'clib/C Caller' has not specified a function to call, or the specified function 'input' does not exist. ''

I followed the exact steps as in Integrate C Code Using C Caller Blocks - MATLAB & Simulink - MathWorks Deutschland

But error still remains.

Can somebody help me?

Hi Besme James, from your query it can be taken that you are trying to use C caller block to call your pre-defined C program. From the statements I assume you have added the header files, source codes in the Configuration parameters -> Simulation target. Ensure that you have enabled both:

• Import custom code
• Enable global variables as function interfaces

To use the input variables from the custom code inside Simulink.

The following documentation may be helpful:

Thankyou :) I checked with all those parameters but the error stays.

It might be a stupid idea but you could get a similar behavior when you have no valid mex compiler installed

Check in Matlab that you have MinGW addon or something similar
