The syntax of this file looks complicated. In fact, you typically only have to change the DE-

FINES section. The various items of the file are detailed below.

5.4.1.1 CFLAGS = -m$(MODEL) -I$(INCDIR) -c -g -Wa,-alhd=$*.lis

CFLAGS is a variable that contains the options that govern the working of the C-compiler. Re-

ferring to the option table of the compiler, it means:

5.4.1.2 LDFLAGS = -nostdlib -T$(SCRIPTFILE) -Wl,-Map,$(APPLI).map

LDFLAGS is a variable that contains the options that govern the working of the linker. The op-

tions are:

Option

Meaning

-m$(MODEL)

Defines the memory model to use.

-I$(INCDIR)

Defines user header files path.

-c

Output an object file for later linking.

-g

Include in the object file all necessary information for the debugger to allow it to use

symbolic names.

-Wa,-alhd=$*.lis

Tells the gcc9 to transmit the option string -alhd=$*.lis to the assembler. These op-

tions makes the assemble generate the most complete assembly listing file to help

finding problems more easily.

Option

Meaning

-nostdlib

Inhibits the use of standard startup files or libraries.

-T$(SCRIPTFILE)

Tells the linker to use the specified script file.

-Wl,-Map,$(APPLI).map

Tells gcc9 to transmit the -Map $(APPLI).map option string to the linker. This

option will make the linker print a link map in the map file.
