make: *** 没有指明目标并且找不到 makefile。 停止。

这是什么意思呢？

flex 这个没安装 ，

sudo apt-get install flex

试试

再 ./configure

我不用下载那个 flex吗？ 直接执行你发的那个命令？

加我QQ吧 1254511900

就是执行这个命令，不过看你的提示符是# 应该不用打sudo
apt-get install flex
这样应该就可吧

按照你的 代码 弄完后 又出现了 这个 configure: error: bison was not found, please install

你加我QQ吧 好吗/？ 帮帮我 拜托你啦 1254511900qq

我不是大神，反正编译的时候 找error 发现缺什么就装什么就对了
