Chapter4. Compiling Application
4.2 Writing a Makefile
In order to compile an application, Makefile should be created or modified and all compile information should be
correctly defined.
The following shows a Makefile of the sample program at /src/Eddy_APPs/.
The figure below shows part where the environment setting values needed at compiling process are configured. It
contains environment values needed when running Make command. When the user wants to compile, add the name
at “TARGET” inside red box marked below.
For example, you can add Hello_World.
First you can make Hello_World.c as follows.
CROSS = /opt/lemonix/cdt/bin/arm-linux-
LDFLAGS += -L/opt/lemonix/cdt/lib -L/opt/lemonix/cdt/bin
IFLAGS += -I/opt/lemonix/cdt/include -I./include
CFLAGS = -O2 -g -Wall -Wno-nonnull
DEST = ../../ramdisk/root/sbin
DEST_ETC = ../../ramdisk/root/etc
CC
= $(CROSS)gcc
STRIP = $(CROSS)strip
AR = $(CROSS)ar
TARGET
= Hello_World ddns_agent udp def pinetd tcp_server tcp_client
tcp_multiplex tcp_broadcast detect portview upgrade eddy loopback rt-test
