SNMP入门教程：Windows下编译

news 2025/8/12 12:01:37

net-snmp提供的官方库太老了，需要自己编译新版本。

从net-snmp下载最新版源码。

2025.08.05 最新版是5.9.4

解压后发现源码目录没有提供Makefile或者CMakeLists.txt等文件，只有一个configure脚本，这个脚本是Linux下常用的。

在win32子目录下发现有build.bat的文件，应该是用于编译的脚本。

perl

到Strawberry Perl下载x64位，安装即可。

当前版本为5.40.2，安装完成后自动添加环境变量。

openssl

v3版本需要openssl库，这里使用vcpkg安装

vcpkg install openssl

修改源码

编译流程对Windows不友好，根据实际编译流程，修改部分文件内容。

build.pl

在/win32/build.pl中添加变量，解决总是编译32位程序问题。

my $target_arch = $ENV{TARGET_CPU} ? $ENV{TARGET_CPU} : $ENV{Platform} ?$ENV{Platform} : "x86";
my $target_arch = "x64";

一旦编译了32位库，那整个环境就被污染了，只能删除源码重来。

net-snmp-config.h

在/win32/net-snmp/net-snmp-config.h.in中找到1777行

修改将要链接的库名称。

编译

打开VS2022的x64本机命令行环境，进入win32子目录。
