swift - 切换到 macOS Catalina 后，Modulemap 将无法编译 - tcp_var.h

Question

我是一个跟踪网络速度的小工具的开发人员。该代码驻留在一个使用模块映射的小框架中，因此我可以在 Swift 中使用 C 代码。

这是我的(旧)模块图:

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 *
}

切换到 macOS Catalina 后，不再找到/usr/include/文件夹，因此我必须更改它们:

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.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" // > ip.h (in_addr), > tcp.h (tcp_seq)
    header "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/netinet/tcpip.h" // > ip.h (in_addr)

    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 *
}

我已经做了一些更改，因为添加完整路径后，模块映射不再编译。我收到以下错误:

在需要之前，必须从模块“Darwin.POSIX.netinet.tcp”导入“tcp_seq”声明

完整版:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/netinet/tcp_var.h:120:2:必须导入“tcp_seq”声明在需要之前从模块“Darwin.POSIX.netinet.tcp”中获取。

我不明白这一点，因为定义结构的头 tcp.h 是在 tcp_var.h 头之前导入的。

我该如何解决这个问题？

我删除了 tcp.h header 导入，现在它可以编译了。
