C and C++ Compilers

The search path

Table 2-2 shows how the various command-line options affect the search path used by

the compiler when it searches for included header and source files. The following

conventions are used in the table:

:mem

The in-memory file system where the ARM compilers store ANSI C and

some C++ header files. See The in-memory file system on page 2-6 for

more information.

ARMINC

The list of directories specified by the

ARMINC

environment variable, if it

is set.

The current place. See The current place on page 2-6 for more

information.

Idir and jdirs

The directories specified by the

-I

and

-j

compiler options.
