在mac can'上编译VLC；找不到MacOSX.sdk

在VLC macOSCompile wiki页面之后。使用单个命令生成说明。我使用Xcode 11.3.1命令行工具、开发人员签名等运行10.14.6

重要提示--我的MacOSX.sdk文件位于以下位置： /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk

通过构建来创建makefile，完成引导并运行make，一切都很好。然后我得到以下错误——如何将VLC指向MacOSX.sdk文件所在的位置

如何设置vlc的“contrib环境”

请注意，在下面的代码片段中，contrib将MacOSX.sdk文件指针设置到错误的位置-如何修复

我需要在vlc源代码中编辑一些内容吗？谢谢错误：

cf:

。/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)

用法：extras/package/macosx/build.sh[选项] 在当前目录中生成vlc 选项： -给我一些帮助 -保持安静 -j要使用的芯的力数 -r重建一切（工具、工具、vlc） -从源代码重新编译contrib -p为所有工件构建包 -我创建了一个可安装的包（n:nightly，u:unsigned stripped release archive） -k使用指定的sdk（默认值：/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk） -a使用

xcrun--show sdk path

将sdk设置为其他方式

xcrun

使用环境变量$SDKROOT

注意：您可能希望安装和使用版本化的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

受版本控制的SDK在旧Xcode和上可用

“contrib环境”的设置全部由“单个命令”处理。

谢谢！我有MacOSX10.15.sdk，可以指出这一点——非常感谢。当然可以。您将能够使用该SDK以macos 10.15+为目标。
