调研方向

使用 MSVC 2019、LLVM 11.1.0、OIIO 2.4.8.0 和 USED_BATCHED=b8_AVX 标志复现 Windows 构建。检查 Windows 批量构建和链接器配置，以确定报告的 OSL 符号为何无法解析；构建成功完成且不再出现这些链接器错误即表示完成。

描述

Problem

Building with USE_BATCHED options on Windows fails due to unresolved external symbols.

Expected behavior:
Successful build with USE_BATCHED option.

Actual behavior:
There are quite a few unresolved symbols, here are a few representative ones when using USE_BATCHED=b8_AVX :
