Build Process

Set up compiler or IDE, configure and initiate build process, troubleshoot compiler errors

Before you can build an executable program or shared library for a model, choose and set up a compiler or IDE and configure the target environment. Several methods are available for initiating the build process. Tooling is available for reloading, rebuilding, and relocating generated code.

If your system includes referenced models, reduce build time and control whether the code generator regenerates code for the top model.

To improve the speed of code execution, consider using available profiling capabilities.
