arm-linux下 編寫Makefile

c代碼 a.c如下

int main(int argc ,char **argv)

{

        printf("hello world!/n");

        return 0;

}

方法1

Makefile 内容如下

CROSS=/usr/local/arm/3.4.1/bin/arm-linux-

CC=gcc

all:

 $(CROSS)$(CC) -o test a.c

儲存後

[[email protected] src]# make

/usr/local/arm/3.4.1/bin/arm-linux-gcc -o test a.c

檢視生成的檔案

[[email protected] src]# ls

a.c  Makefile  test

砍下檔案屬性

[[email protected] src]# file test

test: ELF 32-bit LSB executable, ARM, version 1 (ARM), for GNU/Linux 2.4.3, dynamically linked (uses shared libs), for GNU/Linux 2.4.3, not stripped

方法2 帶參數

Makefile 内容如下

CROSS=

CC=gcc

all:

 $(CROSS)$(CC) -o test a.c

儲存

生成目前系統程式

[[email protected] src]# make

gcc -o test a.c

a.c: In function ‘main’:

a.c:3: 警告：隐式聲明與内建函數 ‘printf’ 不相容

生存arm 下的程式

[[email protected] src]# make CROSS=/usr/local/arm/3.4.1/bin/arm-linux-

/usr/local/arm/3.4.1/bin/arm-linux-gcc -o test a.c
