无法使用gdb进入printf函数

Question

我无法使用gdb进入printf函数。我每次点击＆＃34;进入＆＃34;，＆＃34;跳过＆＃34;我都在使用CLion。或者＆＃34;强制进入＆＃34;，同一行返回，最终退出程序。

我用最小的优化编译了程序：

CC=gcc
CFLAGS=-Wall -ggdb -O0 -g3
OBJECTS=main.c

permute: $(OBJECTS)
    $(CC) $(CFLAGS) $(OBJECTS) -o permute

clean:
    rm $(OBJECTS) permute

我还在控制台上使用了stepi。有什么问题？

编辑：

启动gdb时收到以下消息：
