macOS Catalina 上缺少系统标头 (/usr/include)

Question

我刚刚安装了 macOS Catalina 10.15 GM。不幸的是，我的应用程序框架都无法编译。找不到系统头文件。在 macOS Mojave 上有一个变通方法，但它不再有效，文件不会被下载（变通方法在这里解释）

键入时xcrun --show-sdk-path,/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk会打印在终端上。此文件夹还包含所有必需的标题。我如何告诉 Xcode 使用这些文件？

这是我的 module.modulemap 的样子：

module PrivateNetwork [system]
{
    header "/usr/include/sys/socketvar.h"
    header "/usr/include/net/if_dl.h"
    header "/usr/include/net/if_types.h"
    header "/usr/include/net/if.h"
    header "/usr/include/netinet/in.h"
    header "/usr/include/netinet/tcp.h"

    header "/usr/include/netinet/tcp_var.h"
    header "/usr/include/netinet/tcpip.h"
    header "/usr/include/netinet/tcp_fsm.h"
    header "/usr/include/netinet/ip.h"
    header "/usr/include/netinet/ip6.h"

    export *
}

错误： Header '/usr/include/sys/socketvar.h' not found

Answer 1

您可以将 CPATH 设置为头目录。

export CPATH="/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/"

Answer 2

为了解决这个问题，我只是将完整路径添加到模块映射中。如果有更好的方法，请告诉我，但至少现在文件可以编译（我还必须重新排序条目）：

module PrivateNetwork [system]
{
    header "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/sys/socketvar.h"

    header "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/netinet/ip.h"
    header "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/netinet/ip6.h"

    header "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/netinet/tcp_fsm.h"
    header "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/netinet/tcp_var.h"
    header "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/netinet/tcpip.h"

    header "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/net/if_types.h"
    header "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/net/if.h"
    header "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/net/if_dl.h"

    export *
}
