交叉编译移植时makefile怎么写？

廖佳才 2016-09-10 11:52:48

现在准备移植一个程序到S32V234的板子上
之前有一个FSCW的程序，实在linux3,7内核的版本上运行的，已经有所有的工程文件，.a和.o文件都有
我需要把它改成在当前的l开发板linux4.2版本上编译生成可执行文件，怎么做？
下面是之前的makefile：
CROSS_COMPILE = arm-linux-gnueabi-
CC=$(CROSS_COMPILE)g++
LINK=$(CROSS_COMPILE)g++
TARGET = a10_mdas

OBJ = main.o \
capture.o \
draw_420p.o \
fontinfo.o \
ksc5601.o \
gxbdf.o \
g2d.o \
AdasProcess.o

INC = -I/. -W -Wall -I/home/sylee/project/a20/lichee/linux-3.4/include
CFLAGS = -O3 -c -march=armv7-a -mtune=cortex-a8 -mfpu=neon -ftree-vectorize -ffast-math -mfloat-abi=softfp
LIBS = ./libmdas.a -lpthread

all: $(TARGET)

$(TARGET): $(OBJ)
$(LINK) -o $(TARGET) $(OBJ) ${LIBS} log.o

%.o: %.c
$(CC) $(INC) $(CFLAGS) -Wall -c $^ -o $@

clean:
rm -f $(TARGET) $(OBJ)

我现在要移植的板子的makefile是这样的（这个是一个在当前的开发板上可以运行的APP的makefile）：

# nbuild packages
ODIR := $(shell basename `pwd`)

SYS := $(shell echo $$OSTYPE)
ifeq ($(SYS),)
NBUILD_PLATFORM := linux

请问大神，之前的程序移植到当前的开发板上要怎么该makefile？工程文件中涉及系统的东西还要改哪些东西？难不能把现在的makefile的各个语句解释一下？
注：之前的程序不需要现在的SDK_ROOT文件夹下的库支持
