警告C4003：宏'max'的实际参数不足 - Visual Studio 2010 C ++ [英] warning C4003: not enough actual parameters for macro 'max' - Visual Studio 2010 C++

问题描述

在Visual Studio 2010 SP1上编译openFrameworks 007项目时，我有以下警告：

I have the following warnings while compiling an openFrameworks 007 project on Visual Studio 2010 SP1:

d:\pedro\development\videoflow\openframeworks\libs\openframeworks\types\ofcolor.h(127): warning C4003: not enough actual parameters for macro 'max'
d:\pedro\development\videoflow\openframeworks\libs\openframeworks\types\ofcolor.h(128): warning C4003: not enough actual parameters for macro 'max'
d:\pedro\development\videoflow\openframeworks\libs\openframeworks\graphics\ofpixels.h(150): warning C4003: not enough actual parameters for macro 'max'
d:\pedro\development\videoflow\openframeworks\libs\openframeworks\graphics\ofpixels.h(151): warning C4003: not enough actual parameters for macro 'max'

从我可以告诉这个警告通常后面跟错误，但在我的情况下一切正常。受影响的代码如下：

From what I could tell this warnings are usually followed by errors but in my case everything works ok. The affected code is below:

const float srcMax = ( (sizeof(SrcType) == sizeof(float) ) ? 1.f : numeric_limits<SrcType>::max() );
const float dstMax = ( (sizeof(PixelType) == sizeof(float) ) ? 1.f : numeric_limits<PixelType>::max() );

我尝试在预处理器上设置NOMINMAX，但由于openFrameworks也在onConstants.h中定义了NOMINMAX。

I tried to set NOMINMAX on the preprocessor but since openFrameworks also defines NOMINMAX on ofConstants.h I get a bunch of warnings that NOMINMAX is already defined.

我试图在受影响的openFrameworks文件中定义NOMINMAX，但它会导致相同的警告（实际上，如果我分析文件包括onColor.h和Pixel.h，它们最终包含Constants.h，因此应该定义NOMINMAX）。

I have tried to define NOMINMAX on the affected openFrameworks files but it results on the same warning (in fact if I analyze the files included on ofColor.h and ofPixel.h they end up including ofConstants.h so NOMINMAX should be defined).

有关如何解决这个问题的任何想法？如果你不...最好是什么？这个警告或一系列警告已经定义了NOMINMAX？

Any idea on how to solve this? If you don't... what would be best? This warnings or a bunch of warnings that NOMINMAX is already defined?

编辑：

错误我在谈论这些：警告C4003和错误C2589和C2059 on：x = std :: numeric_limits< int> :: max（）;

如果我试图重现一个干净的C ++项目的问题。但在我的openFrameworks项目，我只是得到警告。

I get this (the warning plus 2 errors) if I try to reproduce the problem on a clean C++ project. But on my openFrameworks project I just get the warnings. That's why I get confused!!

推荐答案

添加 #undef max 相关文件的顶部。
