perl - 在 Windows 10 上使用草莓 perl 安装 Net::Pcap

Question

我正在尝试使用可移植草莓 Perl v5.28.1 版本安装 Net::Pcap (https://metacpan.org/pod/Net::Pcap)，以下是我的步骤:

1.我从 https://nmap.org/npcap/#download 安装了 npcap (winpcap for windows 10 )

2.我从https://nmap.org/npcap/#download下载了npcap sdk

3.我将 SDK zip 文件夹解压缩到 c:/WdpPack 并验证 Include 和 Lib 文件夹是否包含头文件和库

4.然后运行以下命令

perl Makefile.PL INC=-IC:/WpdPack/Include "LIBS=-LC:/WpdPack/Lib -lwpcap"

我收到以下错误消息:

socket.h patched... ok
looking for -lwpcap... yes
checking for pcap_lib_version() in -lwpcap... no
        - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
You appear to lack the WinPcap developer pack.

If it is installed in a non-standard location, please try setting the LIBS
and INC values on the command line.  For instance, if you have unzipped the
developer's pack in C:\WpdPack, you should execute:

    perl Makefile.PL INC=-IC:/WpdPack/Include "LIBS=-LC:/WpdPack/Lib -lwpcap"

Or get and install the WinPcap developer's pack from
  http://www.winpcap.org/install/

知道如何解决这个问题吗？

Answer 1

我可以通过从 C:\WdpPack 移动 SDK 文件夹来编译它。给我的C:\User文件夹。我对 Windows 不太熟悉，所以我不确定为什么会这样，也许与权限有关？

更新 :

运行后perl Makefile.PL , 运行 gmake编译模块失败并出现错误:

要解决此问题，请编辑文件 stubs.inc :

现在gmake编译文件，但链接器失败:

这里的问题是我们链接到了 32 位库 wpcap.lib ，见 this邮政。事实证明，在文件夹Lib/x64的SDK中有一个64位版本的库。 .所以我们必须重新运行 Makefile.PL使用正确的库路径:

perl Makefile.PL INC=-IC:/Users/Me/Libraries/npcap/Include "LIBS=-LC:/Users/Me/Libraries/npcap/Lib/x64 -lwpcap"

(更改上述命令中的路径以符合您的 SDK 安装目录)然后重新运行 gmake .
