C和C ++命名问题？ [英] C and C++ naming issues?

问题描述

http://www.gubbe.ch/code /libcfgparse...8h-source.html


该页面包含一个标题，当包含时未定义任何

的typedef或该文件中的任何值引用。对于

实例，我包含了该文件，然后尝试了这个：


switch（file.get_type（" valid_operating_systems"））

{

case CFG_ITEM_NONE：cerr<< " NONE" << ENDL; break;

case CFG_ITEM_INTEGER：cerr<< " INT" << ENDL;休息;

案例CFG_ITEM_BOOLEAN：cerr<< " BOOL" << ENDL; break;

case CFG_ITEM_FLOATINGPOINT：cerr<< " FLOAT" << ENDL;中断;

案例CFG_ITEM_STRING：cerr<< " STR" << ENDL;中断;

案例CFG_ITEM_CONTAINER：cerr<< " CONTAINER" << ENDL;休息;

默认值：cerr<< 谁知道他妈的？！ << endl;

}


使用g ++编译时，我收到一条错误消息，指出这些

标识符都不存在。但它们很明显地定义在

我包含的文件中！如果我将CfgItemType的定义复制到我的

源文件中，它编译就好了。我真的很想了解

如果有人能解决这个问题，那到底是怎么回事。


谢谢。

That page contains a header that when included does not define any of
the typedefs or any of the value references that are in that file. For
instance, I included that file and then tried this:

switch (file.get_type("valid_operating_systems"))
{
case CFG_ITEM_NONE: cerr << "NONE" << endl; break;
case CFG_ITEM_INTEGER: cerr << "INT" << endl; break;
case CFG_ITEM_BOOLEAN: cerr << "BOOL" << endl; break;
case CFG_ITEM_FLOATINGPOINT: cerr << "FLOAT" << endl; break;
case CFG_ITEM_STRING: cerr << "STR" << endl; break;
case CFG_ITEM_CONTAINER: cerr << "CONTAINER" << endl; break;
default: cerr << "WHO THE FUCK KNOWS?!" << endl;
}

When compiled with g++ I get an error saying that none of those
identifiers exist. But they are quite obviously defined right there in
the file I included! If I copy the definition for CfgItemType into my
source file it compiles just fine. I would really like to understand
what the hell is going on here if anyone can figure that out.

Thanks.

我不这么认为，聪明人。

I don''t think so, smartass.

我已经知道发生了什么。无论如何，谢谢。

I have figured out what is going on. Thanks anyway.
