构建 skia 时出错：机器类型 x64 与 x86 冲突

Question

我正在尝试按照此处的说明构建 Skia https://skia.org/docs/user/build/。我使用 Visual Studio 安装程序为 Windows 安装 C++ clang 工具，然后按如下方式配置 skia：

bin/gn gen out/Shared --args='clang_win="C:\Program Files (x86)\Microsoft Visual Studio19\Community\VC\Tools\Llvm" is_component_build=true is_debug=false is_official_build=true skia_use_system_expat=false skia_use_system_libjpeg_turbo=false skia_use_system_libpng=false skia_use_system_libwebp=false skia_use_system_zlib=false skia_use_system_icu=false skia_use_system_harfbuzz=false target_cpu="x64"'

然后我运行 ninja -C out/Shared 但是在构建过程中我得到以下错误：

FAILED: skia.dll skia.dll.lib skia.dll.pdb

我是运行 Windows 11 的 64 位版本。有人知道问题出在哪里吗？

好的，事实证明出于某种原因（不确定是什么），Skia 使用 Visual Studio 安装程序安装的 LLVM 版本存在问题。我直接从他们官网下载了LLVM然后运行:

bin/gn gen out/Shared --args='clang_win="C:\Program Files\LLVM" is_component_build=true is_debug=false is_official_build=true skia_use_system_expat=false skia_use_system_libjpeg_turbo=false skia_use_system_libpng=false skia_use_system_libwebp=false skia_use_system_zlib=false skia_use_system_icu=false skia_use_system_harfbuzz=false target_cpu="x64"'

运行这个 Skia 构建没有任何错误。
