$ADI_DSP
This macro expands into the path of the VisualDSP++ installation
directory. Use this macro to control how the linker searches for
files.

User-Declared Macros

The linker supports user-declared macros for file lists. The following syn-
tax declares

ration with a semicolon. The linker processes the files in the listed order.

LDF Macros and Command-Line Interaction

The linker receives commands through a command-line interface, regard-
less of whether the linker runs automatically from the VisualDSP++
IDDE or explicitly from a command window. Many linker operations,
such as input and output, are controlled through the command-line
entries. Use LDF macros to apply command-line inputs within LDF.
Base your decision on whether to use command-line inputs in the
or to control the linker with LDF code on the following considerations.
• An .

generic LDF that can be used in multiple projects. Because the
command line can specify only one output, an .

• An .
