Configure Build Process of Generated Code
R2026bFor certain applications, you might want to control aspects of the build process
that occur after C/C++ source code generation but before compilation. To specify
additional build files and flags from inside your MATLAB® code, use the coder.updateBuildInfo function. Alternatively, create a RTW.BuildInfo object in your workspace and use the associated object
functions to specify your build options. When you are working with external code
integration or you have multiple functions that use the same build information,
customize the build process by using the coder.ExternalDependency class.
Use classes in the target
namespace to manage target hardware and build tool information. For example,
register new target hardware for code generation, set up target connectivity for
external mode and processor-in-the-loop (PIL) simulations, or create custom CMake
toolchain definitions for building generated code on your development
computer.
