2 准备代码
$ mkdir ~/helloworld_src
放入 helloworld.c Makefile:
helloworld.c:
#include <stdio.h>
#include <unistd.h>
int main(int argc, int *argv[])
{
while(1)
{
printf("Hello world\n");
sleep(1);
}
return 0;
}
Makefile:
OBJS=helloworld.o all: helloworld helloworld: $(OBJS) $(CC) $(LDFLAGS) -o helloworld $(OBJS) $(OBJS): %.o: %.c $(CC) $(CFLAGS) -c -o $@ $<
