You can use a custom toolchain when generating a static or dynamic library or an executable. You cannot use one to generate MEX functions. To specify which compiler to use for MEX-function generation, see Setting Up the C or C++ Compiler).
Before using the custom toolchain, register the custom toolchain, as described in Register the Custom Toolchain.
Use coder.config to create a configuration object.
For
example:
cfg = coder.config('exe');
Get the value of config(end).Name from the
rtwTargetInfo.m file. Then assign that value to the
cfg.Toolchain property:
cfg.Toolchain = 'mytoolchain v#.#' |
'buildartifact (platform)'
Perform other steps required to generate code, as described in Deployment. For example, specify the path and file name of the source code:
cfg.CustomSource = 'filename_main.c'; cfg.CustomInclude = pwd;
When you generate code using the codegen function, specify the configuration object that uses the custom
toolchain. For
example:
codegen -config cfg filename
You have completed the full workflow of creating and using a custom toolchain described in Custom Toolchain Registration.
