CentOS7 下

CentOS 下编译过，但没使用 so 文件执行过代码

编译工具安装

yum -y install gcc automake libtool m4 autoconf dos2unix

dos2unix 主要是处理 win 下和 linux 换行不一致导致的编译报错。如果不是在 Win 下下载然后传输到 Linux 下的，不用执行

find . -type f -print0 | xargs -0 dos2unix

JDK安装
参考

yum install java-1.8.0-openjdk* -y

编译
然后按照官方流程执行即可

git clone https://github.com/OpenNMS/jicmp.git
cd jicmp
git submodule update --init --recursive
autoreconf -fvi
./configure
make

Win64下

win 的 lib 包如何在 Linux 下直接打包或者使用 MinGW，这里就不知道了，因此直接使用的是 vs 进行处理，同时，由于原仓库使用的 vs 版本较老 & 依赖上面处理得到的一个头文件（org_opennms_protocols_icmp_IcmpSocket.h），这里就使用 vs 2022 进行处理。

首先需要使用 vs 打开源码 win32 下的解决方案，因为有一些配置需要和它一样（跟着我处理就不用打开了）。

新建【动态链接库】的解决方案，解决方案与项目直接放同一目录

vs 项目配置

ws2_32.lib;%(AdditionalDependencies)

C:\Program Files\Java\jdk1.8.0_202\include\win32;C:\Program Files\Java\jdk1.8.0_202\include;%(AdditionalIncludeDirectories)

代码复制
jicmp\win32\config.h、icmp.h 复制到项目目录下
jicmp\org_opennms_protocols_icmp_IcmpSocket_Logger.h 、IcmpSocket.h 、IcmpSocket.c、byteswap.h 复制到项目目录下

再在项目中头文件和源文件添加现有项

原来的：dllmain.cpp、framework.h、pch.h、pch.cpp 不用动

代码改动

#define __WIN32__
#define HAVE_SETSOCKOPT
#define WIN32_LEAN_AND_MEAN
