About
$(TOOL_DIR)
The [Include Paths (-I)] column lists "
$(TOOL_DIR)/include
" that is set by default.
$(
environment variable
)
is a macro defined in the makefile that is generated when you build a project.
TOOL_DIR
is the environment variable in which the path to the gnu17 tool directory is defined. The de-
fined contents can be verified in the [Environments] tab page.
Example: If the gnu17 tools have been installed in the c:\EPSON\gnu17 directory
TOOL_DIR = c:/EPSON/gnu17
Since the macro is replaced with the contents of the environment variable described in
()
during execution
of make.exe ,
-I$(TOOL_DIR)/include
will be resolved to
-Ic:/EPSON/gnu17/include
.
The [Environments] tab page allows the user to define environment variables similar to
TOOL_DIR
. The
environment variables defined here may be used for specifying include file and library file paths in the build
options. Refer to Section 5.10.1 for details of the [Environments] page.
