The best way to set this up is by registering a custom toolchain for your build process. A toolchain is simply a collection of tools used to build the code that gets generated from one of our coder products (in this case Embedded Coder generating code from a Simulink model). Generally speaking, custom toolchain registration can be somewhat involved due to the flexibility in this method, and specifying all of the different aspects can be time-consuming. Fortunately, we already have an example that registers a toolchain for building a 32-bit DLL on a 64-bit Windows machine using Visual Studio. To access the example, execute the following command in the MATLAB command window for release-specific documentation:
>> web(fullfile(docroot, 'coder/ug/build-32-bit-dll-on-64-bit-windows(r)-platform-using-msvc-toolchain.html#responsive_offcanvas'))
The example itself is in the form of a script that registers the toolchain for use with MATLAB Coder, but all toolchains can be used across the Coder products, so it should be suitable for our purposes as well.
To start, follow the example up until the section titled "Create Code Generation Configuration Object". This means the last command you should have run should be "RTW.TargetRegistry.getInstance('reset');". We don't want to run the whole example because they remove the new toolchain in the cleanup at the end of the example. Notice that there's a 'tc' variable of class Toolchaininfo created in the base workspace.
Then we need to open the Simulink model and make a few modifications to ensure that we are set up properly to use the new toolchain. First, we modify the Hardware implementation to specify that we are targeting a 32-bit Windows computer as seen below:
Next, we need to ensure that we are using "ert_shrlib.tlc" to generate our shared library.
Save the model, close the configuration parameter pane, and reopen it. Then, all we need to do is choose our new toolchain from the list of toolchains:
And then we should be all set to generate a 32-bit DLL.
For more information about custom toolchains, you can refer to the documentation page detailing the various steps of custom toolchain creation and registration. To access this documentation, execute the following command in the MATLAB command window:
>> web(fullfile(docroot, 'coder/ug/what-is-a-custom-toolchain.html'))
Some potential troubleshooting steps: Sometimes after setting the hardware, the toolchain still does not appear under the dropdown. To resolve this, make sure that the hardware settings have been applied, and close the configuration parameters. Reopen the configuration parameters and you should see the toolchain appear as an option. Additionally, saving the model after applying the hardware change can allow the new toolchain to be found.
