Hello,

I am using the C/C++ code block to include some custome C code in my model. I am buiilding the code by using the "Build" button pictured below:

This works fine and produces a C source file.

My issue is when I CodeGen I have to manually include this Custom Code file in the folder each time (it gets deleted otherwise).

I am curious is there a way to control where this C/C++ codeblock builds its file and how I can have that build location to be the same as CodeGeneration ? Right now the C/C++ function always builds to the root directory of my simulink project.

Hello Piyush,

Thanks for your comment.

The C/C++ block is part of my model, I am generating code using embedded coder.

The generated code references the custom code just fine, I would just like to avoid the manual process of having the place the custom code in the CodeGen folder each time.

The requirement for my project is all the neccessarry code be placed in a specific folder, it does not work to just have include paths to the directory.

and to be clear all the custom code is already included inside the C function block.

You do not need to place the custom code in the CodeGen folder ... in fact you should not place it there, as it will get deleted when you regenerate code for your model. Place the .c and .h files in a different folder and then:

In the "Include Directories" section of the custom code, specify the path to your header file
In the "Source Files" section, specify the full/relative path to your C files ( for example c:/work/src/ABC.c )

Thanks.

Mark.
