Compile and link generated code

Since R2020b



buildResults = codebuild(buildFolder) loads data from the buildInfo.mat file in buildFolder, generates a makefile in buildFolder, and uses the specified toolchain or template makefile to compile source code that is registered in the RTW.BuildInfo object. If the object is at the top of a hierarchy, the function performs the process for each object in the hierarchy.

The function saves compilation artifacts, including object code files, in buildFolder.

The function returns an object that contains the display output. To view the output, run disp(buildResults).

codebuild(buildFolder, Name,Value) specifies additional options using one or more name-value pairs.

codebuild(buildInfo, Name,Value) compiles the code specified in buildInfo using one or more name-value pairs.


Relocate and Compile Generated Code

For an example that shows how to relocate and compile generated code in another development environment, see Compile Code in Another Development Environment.

Input Arguments

collapse all

Path to the build folder, which typically contains the generated source code. The folder must contain the buildInfo.mat file.

Example: codebuild(pathToCodeFolder, 'BuildMethod', myToolchain)

RTW.BuildInfo object that contains information for compiling and linking generated code.

Example: codebuild(myBuildInfo, 'BuildMethod','CMake')

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: codebuild(pathToCodeFolder, 'BuildMethod', myToolchain)

Use one of these build methods:

  • Toolchain — Specify the name of the toolchain, for example, 'GNU gcc/g++ | gmake (64-bit Linux)'.

  • Template makefile — Specify the path to the template makefile.

  • CMake — Specify 'cmake', which generates CMakeLists.txt configuration files for the CMake build system. The argument value is case-insensitive. For example, you can also specify 'Cmake' or 'CMake'.

Example: codebuild(pathToCodeFolder, 'BuildMethod', 'CMake')

Specify the type of build output:

  • 'STANDALONE_EXECUTABLE' –– Generates a standalone, executable file.

  • 'MODEL_REFERENCE_CODER' –– Generates a static library.

  • 'MEX_FILE' –– Generates a MEX file. Use this value only for building a simulation target, for example, model reference simulation target (ModelReferenceSimTarget) and accelerator mode.

  • 'SHARED_LIBRARY' –– Generates a dynamic library.

  • 'STATIC_LIBRARY' –– Generates a static library.

Example: codebuild(pathToCodeFolder, 'BuildVariant', 'SHARED_LIBRARY')

Output Arguments

Capture display output from build process. To view the display output, in the Command Window, run disp(buildResults).
