宏中的编译错误 [英] compilation error in macro

问题描述

我已经下载了jsvm软件，并且在编译时遇到很多错误.其中很少如下.

I have downloaded jsvm software, and I am getting many errors while compiling. Few of them is as follows.

/usr/include/c++/4.3/bits/algorithmfwd.h:248:41: error: macro "max" passed 3 arguments, but takes just 2

并且文件algorithmfwd.h如下

And the file algorithmfwd.h is as follows

 template<typename _Tp>
const _Tp&
min(const _Tp&, const _Tp&);
template<typename _Tp, typename _Compare>
const _Tp&
min(const _Tp&, const _Tp&, _Compare);

//min_element

// min_element

推荐答案

在某个地方，您定义了一个宏 max ，如果您定义了该宏，则该宏是不允许的包括标准库中的所有标头(其中包含一组重载了名为 max 的函数).您必须找出这在哪里定义了宏，然后将其删除.两种直接的可能性来了要记住:

Somewhere, you have defined a macro max, which is not allowed if you include any headers from the standard library (which has a set of overloaded functions named max). You'll have to find out where this macro is defined, and get rid of it. Two immediate possibilities come to mind:

• 您已在其中一个标头中将其定义为宏.摆脱它.
• 微软同时定义(或定义—我没有检查VC10)"min"和"max"作为其标头之一中的宏.将/DNOMINMAX 添加到您的编译器选项可消除这种情况.
• 您无法控制的其他库已经定义了它.包裹这个私有标头中的库标头，其中包括库标头，然后做:

• You've defined it as a macro in one of your headers. Get rid of it.
• Microsoft defines (or defined—I've not check VC10) both `min` and `max` as macros in one of its headers. Add /DNOMINMAX to your compiler options to suppress this.
• Some other library you can't control has defined it. Wrap this libraries headers in private headers, which include the library header, then do:

    #undef min
    #undef max

使用这些包装程序，而不是给您的库头文件(以及向图书馆提供者施压以更正此问题).

Use these wrappers instead of the library headers you were given (and pressure the library provider to correct this).
