Question

我是一个可跟踪网络速度的小型工具的开发商。该代码位于一个使用小模块映射的小型框架中，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，因此我不得不更改它们：

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 *
}

我已经进行了一些更改，因为添加完整路径后，modulemap将不再编译。我收到以下错误：

Declaration of 'tcp_seq' must be imported from module 'Darwin.POSIX.netinet.tcp' before it is required

完整版本： /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/netinet/tcp_var.h:120:2: Declaration of 'tcp_seq' must be imported from module 'Darwin.POSIX.netinet.tcp' before it is required。

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

我该如何解决？

Answer 1

我删除了tcp.h标头导入，现在可以编译了。

切换到macOS Catalina后无法编译Modulemap-tcp_var.h
