文件内容：
hello.h
void hello(char name[]);

hello.c
#include <stdio.h>
void hello(char name[])

}

main.c
#include <stdio.h>
#include "../inc/hello.h"
// The second
int main()
{
hello("GCC");
printf("Haha Linux Ubuntu!\n");
return 0;
}
  
Makefile
# String declaration
objects = main.o hello.o
# Command
app : $(objects)
cc -o app $(objects)
main.o : main.c hello.h
cc -c main.c
hello.o : hello.c stdio.h
cc -c hello.c
# Search paths
vpath %.h /usr/include ../inc
# Clean the intermediate files
.PHONY : clean
clean :
rm app $(objects)
