Defines
Macro definitions to appear on compile line as -D directives
Model Configuration Pane: Simulation Target
Description
The Defines parameter specifies preprocessor macro definitions to be added to the compiler command line.
Settings
Enter a list of macro definitions for the compiler command line. Specify the parameters with a space-separated list of macro definitions. If a makefile is generated, these macro definitions are added to the compiler command line in the makefile. The list can include simple definitions (for example, -DDEF1), definitions with a value (for example, -DDEF2=1), and definitions with a space in the value (for example, -DDEF3="my value"). Definitions can omit the -D (for example, -DFOO=1 and FOO=1 are equivalent). If the toolchain uses a different flag for definitions, the code generator overrides the -D and uses the appropriate flag for the toolchain.
