如何解决野牛警告`GrammarCl'的$ 1没有声明的类型

时间：2011-03-23 15:09:05

标签： bison

我在BNF中有一个语法，我使用BNF Converter将这个语法转换成带有C代码的可执行程序。但是，我有一个特定的问题，关于$ 1的`GrammarCl'在GrammarCl.y文件中没有声明的类型，我不知道如何解决这个问题。我已经看了很多论坛并搜索了这个并尝试了很多东西，但仍然不知道如何解决它。

我得到的错误是：

  

gcc -g -W -Wall -c Absyn.c
  flex -PGrammarCl -oLexer.c GrammarCl.l
  gcc -g -W -Wall -c Lexer.c
  Lexer.c：1362：警告：'yyunput'定义但未使用
  Lexer.c：1408：警告：'输入'已定义但未使用
  bison -t -pGrammarCl GrammarCl.y -o Parser.c
  GrammarCl.y：614.70-71：GrammarCl' has no declared type
GrammarCl.y:614.74-75: $2 of GrammarCl'的$ 1没有声明的类型
  make： * [Parser.c]错误1

以下是GrammarCl.y文件中的语法：

对于所有令牌，您不一定需要％type 。许多令牌（如运算符）没有与之关联的类型，但它们仍然可以在语法规则中执行操作。 但是，当你将它发送到某个地方时，你需要设置一个类型。例如， someObject.intVariable = $ 3 应该变为 someObject.intVariable = $ 3 因为你声明你的union的int类型是int _。

在我看来，您没有%type声明，表明词法分析器返回_SYMB_16和_SYMB_14的值。

答案 2 :(得分：0)

您可能必须使用$< 名称类型 >1和$< 名称类型 {{ 1}}，分别是“ name-of-type ”是您的>2成员之一。例如，%union或$<wordaction_>1，任何类型都适合上下文。
