Target Configuration Options

Figure 2-2 shows the Target configuration options of the Real-Time Workshop pane.

Figure 2-2: The Real-Time Workshop Pane: Target Configuration Options

Browse Button

The Browse button opens the System Target File Browser (See Figure 2-8). The browser lets you select a preset target configuration consisting of a system target file, template makefile, and make command.

Selecting a Target Configuration details the use of the browser and includes a complete list of available target configurations.

System Target File Field

The System target file field has these functions:

• If you have selected a target configuration using the System Target File Browser, this field displays the name of the chosen system target file (target.tlc).
• If you are using a target configuration that does not appear in the System Target File Browser, you must enter the name of the desired system target file in this field.
• After the system target filename, you can enter code generation options and variables for the Target Language Compiler. See Target Language Compiler Variables and Options for details.

Template Makefile Field

The Template makefile field has these functions:

• If you have selected a target configuration using the System Target File Browser, this field displays the name of an M-file that selects an appropriate template makefile for your development environment. For example, in Figure 2-2, the Template makefile field displays grt_default_tmf, indicating that the build process will invoke grt_default_tmf.m.

• Template Makefiles and Make Options gives a detailed description of the logic by which Real-Time Workshop selects a template makefile.

• Alternatively, you can explicitly enter the name of a specific template makefile (including the extension) in this field. You must do this if you are using a target configuration that does not appear in the System Target File Browser. This is necessary if you have written your own template makefile for a custom target environment.

• If you specify your own template makefile, be careful to include the filename extension. If a filename extension is not included in the Template makefile field, Real-Time Workshop attempts to find and execute a file with the extension .m (i.e., an M-file).

Make Command Field

A high-level M-file command, invoked when a build is initiated, controls the Real-Time Workshop build process. Each target has an associated make command. The Make command field displays this command.

Almost all targets use the default command, make_rtw. Targets Available from the System Target File Browser lists the make command associated with each target.

Third-party targets may supply another make command. See the vendor's documentation.

In addition to the name of the make command, you can supply arguments in the Make command field. These arguments include compiler-specific options, include paths, and other parameters. When the build process invokes the make utility, these arguments are passed along in the make command line.

Template Makefiles and Make Options lists the Make command arguments you can use with each supported compiler.

Generate Code Only Option

When this option is selected, the build process generates code but does not invoke the make command. The code is not compiled and an executable is not built.

When this option is selected, the caption of the Build button changes to Generate code.

Stateflow Options Button

If the model contains any Stateflow blocks, this button will launch the Stateflow Options dialog box. Refer to the Stateflow documentation for information.
