mac 上的 VLC 编译找不到 MacOSX.sdk

Question

关注 VLC macOSCompile wiki 页面。使用单个命令构建说明。我是运行 10.14.6，带有 Xcode 11.3.1 命令行工具，开发人员签名等

重要说明 -- 我的 MacOSX.sdk 文件位于此处： /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk

通过构建创建 makefile 一切顺利，完成 bootstrap 并运行 make。然后我收到以下错误信息——如何将 VLC 指向我的 MacOSX.sdk 文件所在的位置？

IOW 如何设置 vlc 的 "contrib environment"？

请注意下面的代码片段，contrib 将 MacOSX.sdk 文件指针设置为错误的位置 - 我该如何解决？

我需要在 vlc 源中编辑一些东西吗？谢谢。错误：

比照：../extras/package/macosx/build.sh -h
它说：

usage: extras/package/macosx/build.sh [options]

Build vlc in the current directory

OPTIONS:
   -h            Show some help
   -q            Be quiet
   -j            Force number of cores to be used
   -r            Rebuild everything (tools, contribs, vlc)
   -c            Recompile contribs from sources
   -p            Build packages for all artifacts
   -i <n|u>      Create an installable package (n: nightly, u: unsigned stripped release archive)
   -k <sdk>      Use the specified sdk (default: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk)
   -a <arch>     Use the specified arch (default: x86_64)
   -C            Use the specified VLC build dir
   -b <url>      Enable breakpad support and send crash reports to this URL
   -d            Disable debug mode (on by default)

您的构建命令还应包括使用 -k 选项的 SDK 的位置：

../extras/package/macosx/build.sh -c -k /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk

script 否则使用xcrun --show-sdk-path 设置SDK。 xcrun 使用环境变量 $SDKROOT.

注意：您可能想要安装和使用版本控制的 SDK，例如在您的问题中，输出显示它的目标是最低 El Capitan、/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk 版本化的 SDK 在旧 Xcode 和 github.

上可用

设置 "contrib environment" 全部由 "single command" 处理。
