gcc max.o les2.c报错

源自：4-2 [Linux C语言] 头文件与函数定义分离

murong@ubuntu:~/workspace/les2$ vim les2.c

murong@ubuntu:~/workspace/les2$ gcc max.o les2.c

les2.c: In function ‘main’:

les2.c:7:16: warning: implicit declaration of function ‘max’ [-Wimplicit-function-declaration]

int maxNum=max(a,b);

为什么会这样，
