Build Configuration

Configuration of build settings such as output file name, location, type, language

To control and configure the build process for generating binary code, there are many parameters and settings. These settings control attributes such as the output build type (MEX, lib, dll, or exe) and C versus C++ language. Other build settings enable you to customize the build output according to specific needs, such as readability, performance, and external code integration. You can modify the build options in the code generation configuration object from the app or from the command line. You can create the configuration object by using coder.config. Open the object in the editing app by using open. To specify additional build files and flags from inside your function code, use coder.updateBuildInfo.

Build Configuration Basics

Configure Build Settings

Configure build configuration parameters at the command line or in the MATLAB® Coder™ app.

Build Process Customization

Control aspects of the build process that occur after code generation but before compilation.

Paths and File Infrastructure Setup

Specify location of custom code.

Share Build Configuration Settings

Export project settings to a code generation configuration object or import the settings into a project.

Specify Configuration Parameters in Command-Line Workflow Interactively

Edit code generation configuration objects interactively.

C Compiler Considerations for Signed Integer Overflows

For accurate results from signed integer C operations, the C compiler must preserve wrap-on-overflow behavior.

Requirements for Signed Integer Representation

Compile generated code on a target that uses a two’s complement representation for signed integer values.

Build Process Support for Folder Names

Troubleshoot build process errors that occur when file system issues prevent file processing.

Specific Build Options

Preserve Variable Names in Generated Code

Improve readability of generated C/C++ code by preserving your variable names in the generated code.

How MATLAB Coder Partitions Generated Code

Select file partitioning method.

Change the Language Standard

For calls to math operations, the code generator uses the language standard that you specify in the build settings.

Specify Data Types Used in Generated Code

Generate built-in C types or MathWorks® predefined types.

Register New Hardware Devices

Extend the range of supported hardware by registering new devices.


Compiler and Linker Errors

Address common causes of errors that occur during build.
