找不到-ly错误 [英] Cannot find -ly error

问题描述

我正在尝试运行lexx和yacc程序，但出现以下错误:

I am trying to run a lexx and yacc program and I got the following error:

/usr/bin/ld: cannot find -ly
collect2: error: ld returned 1 exit status

请告诉我应该添加哪些库?

Plz tell me which libraries am I supposed to add?

推荐答案

我猜问题是，您使用的是yacc版本，而不是旧的AT& T yacc版本，该版本不带有liby(-ly您有).因此，您需要从命令行中删除-ly选项，并提供自己的main和yyerror实现.

I would guess the problem is that you're using a version of yacc other than the old AT&T yacc which doesn't come with liby (the -ly you have). So you need to remove the -ly option from your command line, and provide your own implementations of main and yyerror.
