開始學(xué)linux。我練習(xí)寫的第一個(gè)帶子目錄的makefile文件。
1。建立文件夾 wulong
wulong中含 三個(gè)文件夾 include source pro 和makefile文件。
include 中包含 hai.h頭文件。
source 中包含 hello.c文件。
pro 中包含 haia.c haib.c文件。
makefile文件內(nèi)容有兩種寫法：
makefile 第一種寫法：
／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
CC=gcc ＃選擇編譯器類型為gcc
VPATH= include : pr : source #列明文件存放目錄
hello: hello.o haia.o haib.o
$(CC) -o hello hello.o haia.o haib.o
hello.o:hello.c hai.h
$(CC) -c hello.c
haia.o: haia.c hai.h
$(CC) -c haia.c
haib.o: haib.c hai.h
$(CC) -c haib.c
.PHONY: clean
clean:
rm hello $(obj)
／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
makefile第二種寫法（簡化版）：
／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
CC=gcc #選擇編譯種類
VPATH= include : pr : source #在include pr source 三目錄下查找文件
obj= hello.o haia.o haib.o ＃
hello:$(obj) ＃
$(CC) -o hello $(obj)
$(obj): hai.h
.PHONY: clean
clean:
rm hello $(obj)
／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
hai.h文件內(nèi)容為：
／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
#include "stdio.h"
extern void haiprinta();
extern void haiprintb();
／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
hello.c內(nèi)容為：
／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
#include "../include/hai.h"
int main(void)
{
haiprinta();
haiprintb();
return 0;
}
／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊
haia.c內(nèi)容為：
／／＊＊＊＊＊＊＊＊＊＊＊＊
#include "../include/hai.h"
void haiprinta()
{
printf("hai aaaaaaaaaa\n");
}
／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊
haib.c內(nèi)容為：
／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊
#include "../include/hai.h"
void haiprintb()
{
printf("haib bbbbbbbbbbbbbb\n");
}
／／＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
2。make 調(diào)用makefile生成 可執(zhí)行文件 hello
3. 運(yùn)行 hello顯示打印結(jié)果：
[HAI@localhost wulong]$ ./hello
hai aaaaaaaaaa
haib bbbbbbbbbbbbbb
[HAI@localhost wulong]$
到此結(jié)束，恭喜！
