Pixar USD LNK2019：未解决的外部符号

Question

我正在开发一个 C++ 程序，该程序使用来自 Nvidia (https://developer.nvidia.com/usd) 的 Python 3 预构建库创建一个 .usda 文件。有很多外部库，我无法确定哪个导致了一堆编译器问题。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。

我从研究中得知，我可能缺少包含/lib 目录，或者某些内容是在不同版本上编译的，但我如何才能找到哪些文件丢失或编译不正确？

我使用的是 Windows 10、Visual Studio 2017、Python 3.6 和 Boost 1.68。 Nvidia 库位于 C:\USDP3

包括：C:\USDP3\include C:\Program Files\boost_1_68_0

库：C:\USDP3\lib C:\Program Files\boost_1_68_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>

PXR_NAMESPACE_USING_DIRECTIVE

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

导致这些错误：

Answer 1

您应该在编译步骤设置中正确设置以下内容： 预处理器标志：

TBB_USE_DEBUG=0
YY_NO_UNISTD_H
BOOST_ALL_DYN_LINK
BOOST_PYTHON_NO_PY_SIGNATURES
BUILD_OPTLEVEL_DEV
NDEBUG
NOMINMAX
_CRT_SECURE_NO_WARNINGS
_SCL_SECURE_NO_WARNINGS
_CRT_SECURE_NO_DEPRECATE
_CRT_NONSTDC_NO_DEPRECATE
NO_WARN_MBCS_MFC_DEPRECATION

包括目录：<usd_install>\include;<usd_install>\include\boost-1_70;<Python374>\include

要链接的库：usd_ms.lib（当 USD 编译为整体共享库时）

其他，基本的：arch.lib;pxOsd.lib;sdf.lib;usd.lib;vt.lib;tf.lib;

渲染：hd.lib;hdx.lib;

更多：gf.lib;cameraUtil.lib;trace.lib;hf.lib;（取决于您使用的是哪个。） 他们对应的 dll 应该是可发现的，或者最好应该在同一个目录中。作为您的可执行文件。

检查 USD 的 cmake 文件以更好地了解要包含的内容。
