皮克斯USD LNK2019：未解析的外部符号 我正在使用一个C++程序，使用Nvidia（）的Python 3预构建的库创建.USDA文件。有很多外部库，我无法确定是哪一个导致了大量编译器问题。有一些头文件（具体来说是stage.h、mesh.h）会阻止我的程序编译。我从包中使用的其他头文件不会导致这些错误

我从研究中发现，我可能缺少一个include/lib目录，或者某个文件是在另一个版本上编译的，但是我如何才能找到丢失的或编译不正确的文件呢

我正在使用Windows 10、Visual Studio 2017、Python 3.6和Boost 1.68。Nvidia库位于C:\USDP3中

包括：C:\USDP3\包括C:\Program Files\boost\u 1\u 68\u 0

库：C:\USDP3\lib C:\Program Files\boost\u 1\u 68\u 0 C:\USDP3\libs

示例代码：

#include "pch.h"
#define NOMINMAX
#define TBB_USE_ASSERT 0
#define TBB_USE_THREADING_TOOLS 0
#include "pxr/pxr.h"
#include "pxr/usd/usd/stage.h"
#include <iostream>

int main(int argc, char* argv[])
{
    //Create Stage
    UsdStage::CreateNew("Test.usda");
    std::cout << "Hello World!\n";
}

您缺少指向dll导入库的链接。这是有道理的，但我无法确定缺少哪个dll。我在包中找到的每个库都位于我包含的路径中。此处的错误消息中是否有任何内容可以帮助我找到缺少的文件？此项目中有多少.dll文件？这不是问题缺少
