未定义参考问题antlr4 C ++目标

问题描述 投票：0回答：1

我正在一个编译器设计课程，我试图了解ANTLR4用C ++目标。

好了，这就是我经历：

  1. 我在一档名为写语法“ArrayInit.g4”
  2. 使用ANTLR4工具和命令“antlr4 -Dlanguage = .cpp的-o构建”编制，并得到一堆文件在我还添加了包含主功能int main(){return 0;}一个简单的文件中的“构建/”目录
  3. 下载的C ++运行时，并把它放在一个目录下的“运行时间/”
  4. 在这个阶段，我被困，我无法使用命令编译.cpp文件“G ++ -std = C ++ 11 -I ../runtime -o EXEC *的.cpp”和我收到以下错误信息：

我完全新的C ++，我也许跳过一个基本理念。

EDIT1：我使用的Linux

EDIT2： 当我执行COMMANDE antlr4 -Dlanguage=Cpp -o build我收到了一堆的.cpp和.h文件为：ArrayInitLexer.h，许多人包括antlr4-runtime.h。这个头文件是存在于runtime/文件夹它通过它的自我包括在同一目录许多其他的头文件（ .IE runtime/），其中包含的.h和.cpp文件（我没有看到某或.so文件）。 您可以从here下的C ++目标部分中找到运行时here或直接

c++ g++ antlr4

您编译命令看起来不完全正确。

需要注意的是G ++采用大写-L开关指定位置寻找库和小写-l指定库的文件名联系起来，不包括lib前缀和后缀的文件。因为至少在我的版本看，ANTLR提供了一个“libantlr.a”，这将是-l antlr。

此外，库应该程序源代码或目标文件（S）后给予，因为在大多数情况下，连接器决定什么库的件包括基于他们是否提供知悉它迄今已看到需要的任何符号。

所以，我不知道这是否会解决所有问题，但向前迈进了一步将是：

g++ -std=c++11 -Wall -Wextra *.cpp -L ../runtime -l antlr -o exec

我也采取了添加-W标志，使一组默认的编译器警告，这是一个必须编写新的C ++代码的时候，不管你是新来的语言与否的自由。
