Question

对于通用标题很抱歉，但在C ++编译时我不是专业人士，我似乎无法在这里找到错误。

我正在检查一个官方项目，所以我知道事情应该实际编译得很好。它没有。

如果有人想自己查看代码，请转到：

cvs -d :pserver:jvtuser:jvt.Amd.2@garcon.ient.rwth-aachen.de:/cvs/jvt login
cvs -d :pserver:jvtuser@garcon.ient.rwth-aachen.de:/cvs/jvt checkout jmvc
cd jmvc/JMVC/H264Extension/build/linux
make

当我致电make时，我会收到：

如果有人提出一些指示，我会非常感激......

Answer 1

C ++的标准库不使用或定义max或min作为宏。报告第一个错误的行（/usr/include/c++/4.4/bits/algorithmfwd.h:353）包含带有第三个参数的std :: max模板函数的前向声明。从我在您提供的信息中看到的内容，我认为在您的系统中包含了一些旧标头，它将max()和min()定义为宏。顺便说一下，这是一个常见问题。

您需要识别定义max / min的标头（或源文件），并尝试确定是否有办法配置源代码以在没有该标头的情况下构建。

<强>更新看起来匪徒在源文件中：

> grep -R "#define min" *
include/DownConvertTools.inl:#define min(x, y) ((x)<(y)?(x):(y))
include/H264AVCCommonLib/GlobalFunctions.h:#define min(x,y) ((x)<(y)?(x):(y))
include/H264AVCCommonIf.h:#define min(x,y) ((x)<(y)?(x):(y))
src/test/H264AVCDecoderLibTest/DecoderParameter.h:#define min(x,y) (((x) < (y)) ? (x) : (y))
src/lib/H264AVCCommonLib/CFMO.cpp://#define min(a,b) ((a)>(b))?b:a

重复的定义通常意味着代码无论如何都需要清理，因此您可以先删除宏并将max / min替换为std::max / std::min。

Answer 2

ddraw.lib实际上并未被软件使用，因此您可以安全地从所使用的库链接器列表中删除ddraw.lib，并且解决方案将成功构建。

无法编译C ++项目（宏“max”传递3个参数，但只需2个）
