我想在项目中包含vdb（github.com/mmp/pbrt-v2）
我尝试过vdb的例子，每个例子都可以。
但是在这个项目（pbrt）中，我遇到了错误identifier not found
这是我的代码：
#include "../vdb.h"
#include "stdafx.h"
#include "shapes/heightfieldImproved.h"
#include "shapes/trianglemesh.h"
#include "paramset.h"
// heightfieldImproved Method Definitions
HeightfieldImproved::HeightfieldImproved(const Transform *o2w, const Transform *w2o, bool ro, int x, int y, const float *zs)
: Shape(o2w, w2o, ro) {
nx = x;
ny = y;
z = new float[nx*ny];
memcpy(z, zs, nx*ny*sizeof(float));
nVoxels[0] = nx - 1;
nVoxels[1] = ny - 1;
nVoxels[2] = 1;
ComputeVertexNormal();
vdb_line(0, 0, 0, 1, 1, 1);
}
IntelliSense工作正常，它知道vdb_line()是什么，但是当我构建整个项目时，引发的错误（"vdb_line": identifier not found）
我在win10上使用visual studio 2015
谢谢！
---编辑---
我将include更改为完整路径
#include "C:\Users\ssarcandy\Documents\GitHub\pbrt-v2\src\vdb.h"
仍然得到同样的错误.... 只有一个错误：
"vdb_line": identifier not found

答案 0 :(得分：1)
包含vdb.h的正确位置是stdafx.h之后，而不是之前。默认情况下，如果您的项目设置为使用预编译头，它将忽略源文件中stdafx.h之前的所有包含。你应该在你在帖子中提到的错误之前看到一个告诉你的警告：
warning C4627: '#include "vdb.h"': skipped when looking for precompiled header use
note: Add directive to 'StdAfx.h' or rebuild precompiled header
这是后来编辑失败的方式告诉你它无法找到该功能。
现在，如果在stdafx.h之后移动include语句，则会出现很多错误，其中大部分都是关于WinSock相关名称的重复定义。
那是因为您最终同时包含winsock.h和WinSock2.h。第一个包含在windows.h中，后者又包含在以stdafx.h开头并以parallel.h结尾的长链中。第二个直接包含在vdb.h。
要解决这个问题，你可以通过两种方式解决这个问题：
<强> 1。让windows.h不自动包含winsock.h
为此，在任何其他包含语句之前，在stdafx.h的顶部定义宏WIN32_LEAN_AND_MEAN。
#define WIN32_LEAN_AND_MEAN
这会禁用除winsock.h之外的其他几个标题，因此您在执行此操作时可能会遇到一些新错误。您可以尝试通过在需要的地方直接包含相应的标题来解决这些问题。
我不熟悉PBRT项目及其源代码，我不知道它是否真的使用了WinSock，或者它只是在没有实现的情况下包含了标题，所以我无法准确地告诉你新的问题是什么可能会遇到。
<强> 2。将vdb转换为使用winsock而不是winsock2
我对这个项目不熟悉，所以我不能告诉你这将涉及多少工作。但是初看起来，如果出于某种原因第一种方法失败，它看起来是可行的。
答案 1 :(得分：0)
编译器不知道vdb_line是什么。这条线
#include＆＃34; ../ vdb.h＆＃34;
可能不正确，因为根据你的github链接，头文件确实有 cdb_line deklaration。尝试将vdb.h与显式路径进行验证。将头文件相对于您的工作目录正确放置，以将其包含在＆＃34; ../ vdb.h＆＃34;中。
Intellisense拥有机械师。默认情况下，它仅使用标准包含目录来查找头文件。但是可以添加其他文件，甚至是非项目文件，以便解析智能感知。 intellisense知道 cdb_line 声明并且编译器不知道但为什么我们不得不查看你的visual studio项目设置并不奇怪。
