Template Makefiles and Make Options

The Real-Time Workshop includes a set of built-in template makefiles that are designed to build programs for specific targets.

There are two types of template makefiles:

• Compiler-specific template makefiles are designed for use with a particular compiler or development system.

By convention, compiler-specific template makefiles are named according to the target and compiler (or development system). For example, grt_vc.tmf is the template makefile for building a generic real-time program under Visual C/C++; ert_lcc.tmf is the template makefile for building a Real-Time Workshop Embedded Coder program under the LCC compiler.

• Default template makefiles make your model designs more portable, by choosing the correct compiler-specific makefile and compiler for your installation. Choosing and Configuring Your Compiler describes the operation of default template makefiles in detail.

Default template makefiles are named target_default_tmf. For example, grt_default_tmf is the default template makefile for building a generic real-time program; ert_default_tmf is the default template makefile building a Real-Time Workshop Embedded Coder program.

You can supply options to makefiles via arguments to the Make command field of the Target configuration category of the Real-Time Workshop page. Append the arguments after make_rtw (or make_xpc or other make command), as in the following example.

make_rtw OPTS="-DMYDEFINE=1"

The syntax for make command options differs slightly for different compilers.
