頭是正確的，但

我想包括在項目（github.com/mmp/pbrt-v2）vdb 頭是正確的，但

我曾嘗試VDB的例子編譯錯誤（未找到標識符），每例工作正常。

，但在這個項目（PBRT），我遇到了錯誤identifier not found

這裏是我的代碼：

#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); 
}

智能感知正常工作，它知道什麼vdb_line()是，但是當我建立整個項目，引發的錯誤（"vdb_line": identifier not found）

我使用的Visual Studio 2015年win10

謝謝！

---編輯---
我改變包括爲完整路徑

#include "C:\Users\ssarcandy\Documents\GitHub\pbrt-v2\src\vdb.h"

，仍然得到同樣的錯誤....
那裏只是只有一個錯誤：

"vdb_line": identifier not found

滿滿的日誌

vdb_line（）不是類HeightfieldImproved的成員嗎？ – Raindrop7

您是否可以在構建項目時包含完整的錯誤消息？ – Ionut

vdb_line（）是vdb.h中定義的函數。 – SSARCandy

包含vdb.h的適當位置在stdafx.h之後，而不是之前。默認情況下，如果您的項目設置爲使用預編譯頭文件，它將忽略源文件中stdafx.h之前的所有內容。你應該看到一個警告你在你的文章中提到的錯誤之前告訴你這一點：

warning C4627: '#include "vdb.h"': skipped when looking for precompiled header use 
note: Add directive to 'StdAfx.h' or rebuild precompiled header

這是方式，後來未能編譯告訴你它找不到該功能。

現在，如果在stdafx.h之後移動include語句，則會出現很多錯誤，其中大多數錯誤都與WinSock相關名稱的重複定義有關。這是因爲你最終包括winsock.h和WinSock2.h。第一個包含從windows.h包括在其中包含在從stdafx.h開始並結束於parallel.h長鏈。第二個從vdb.h直接包含。

爲了解決這個問題，你可以通過兩種方式去：

1. windows.h不包括winsock.h自動

要做到這一點，你定義宏WIN32_LEAN_AND_MEAN在stdafx.h頂部，之前的任何其他包括聲明。

#define WIN32_LEAN_AND_MEAN

這禁用了幾個頭的加入除了winsock.h，所以當你這樣做，你可能會得到一些新的錯誤。您可以嘗試通過直接在需要的地方添加適當的標題來解決這些問題。

我不熟悉PBRT項目和它的源代碼，我不知道它是否實際使用WinSock，或者它只是在沒有意識到的情況下包含頭文件，所以我不能確切地告訴你什麼新問題你可能會遇到。

2.轉換到vdb用winsock代替Winsock2的

我不熟悉這個項目無論所以我不能告訴你多少工作，這將涉及。但是，如果由於某種原因第一種方法失敗，首先看起來可行。

GREAT THANKS !!!感謝您對'stdafx.h'的明確解釋，嘗試方法2後，一切正常！ – SSARCandy

編譯器不知道vdb_line是什麼。該生產線

的#include 「../vdb.h」

可能不是因爲頭文件正確，根據你的github上的鏈接，確實有cdb_line deklaration。嘗試使用顯式路徑來驗證vdb.h。將頭文件相對於您的工作目錄正確放置，使其包含「../vdb.h」。

智能感知擁有它的力學。默認情況下，它僅使用標準包含目錄來查找頭文件。但是可以添加其他文件，甚至非項目文件，以便智能感知解析。 intellisense知道聲明並且編譯器不知道爲什麼，我們將不得不考慮您的visual studio項目設置，這並不奇怪。

它肯定有一個https://github.com/zdevito/vdb/blob/master/vdb.h#L160。 –

感謝您的回答，我更新了問題。我包含使用絕對路徑的頭仍然得到相同的結果，智能感知工作正常，但編譯器無法找到它。 – SSARCandy

頭是正確的，但
