#error“must #define __STDC_LIMIT_MACROS before #includeing Support / DataTypes.h” [英] #error "Must #define __STDC_LIMIT_MACROS before #including Support/DataTypes.h"

问题描述

我一直试图按照的教程http://gnuu.org/2009/09/18/writing-your-own-toy-compiler/5/ （使用flex，bison和llvm）但输入行时

I have been trying to follow the tutorial at http://gnuu.org/2009/09/18/writing-your-own-toy-compiler/5/ (using flex, bison and llvm) but when typing the line

g ++ -o parser parser.cpp tokens.cpp main.cpp

g++ -o parser parser.cpp tokens.cpp main.cpp

我收到以下错误：

这样的帖子在互联网上，大多数的答案包括在命令行或使用gcc Makefile定义这些常量。

I have seen lots of posts like this on the internet, and most of the answers include defining these constants on the command line or by using gcc Makefile.

我不明白如何做

推荐答案

将它附加到您的命令行：

Append this to your command line:

-D__STDC_CONSTANT_MACROS -D__STDC_LIMIT_MACROS

关于 -D 命令行选项，请参阅 gcc的预处理器选项的文档。

For more information about the -D command line option, refer to gcc's documentation on preprocessor options.
