Question

我有一个用C编写的程序，它使用XMLLib和从ANTLR生成的词法分析器/解析器。

我的包含如下：

#include    "MyParser.h"
#include    "MyLexer.h"
#include    "antlr3.h"
#include <libxml/tree.h>
#include <libxml/parser.h>

问题是我的程序拒绝编译，错误地用：

如果我不包含前两个包含的所有内容都正确编译（我用一个简单的'return 0'替换了我的main（）函数）。知道是什么原因引起的吗？：（

我的编译命令如下：

gcc *.c -c -lantlr3c -I/usr/include/libxml2

编辑：我从Ubuntu软件包管理器安装了libxml2-dev软件包，如果这有所不同

Answer 1

看起来像是一些宏观问题。 parser.h的第961行包含ID，可以在其中一个标题中定义。

Answer 2

我不确定是否可以恢复该主题，但即使我尝试使用“-I / usr / include / libxml2”，我也遇到了一个更简单程序的问题。但是，一旦我传递了链接参数，代码就能够编译。

Libxml.org（http://www.xmlsoft.org/FAQ.html）的当前常见问题解答说明了这一点：

开发者角落

使用libxml2编译或链接程序的麻烦通常是   问题来自编译器没有得到正确的事实   编译或链接标志。有一个小的shell脚本   xml2-config作为libxml2常规安装的一部分安装   提供这些标志的过程。使用

xml2-config --cflags

获取编译标志和

xml2-config --libs

获取链接器标志。通常这是直接从   Makefile为：

CFLAGS = xml2-config --cflags

LIBS = xml2-config --libs

不确定一年前是否有这个有用的提示。
