@zed1018 刚刚右键打开了下，这效果真的……
WinUI 3 的界面用着中文宋体，怎么看都觉得怪怪的

@ooxxcc

可以看看新增的附言，并没有安装 MacType

@fkdog 然而我的放大倍数是整数倍，Windows 10 和 Windows 11 都是 DPI 200%，而且更神奇的是，Windows 11 并非所有区域都有这个 Bug ，其他地方比如选项卡、标题栏都一切正常。

@superrichman 为了一目了然，附言加上了写字板的情况，因为这样可以把显示效果、字体名称、字号大小、系统版本全都在一张图列出来，结果发现写字板的显示一切正常

最简单的测试：iperf （还有 iperf3 ）

例如，路由器上面开一个 iperf3 -s -p 54321 ，然后在外面连过去试试 iperf3 -p 54321 -c IP 地址

我用软路由的其中一个原因是因为我这边的 IPv6 的前缀分配很奇怪。

我目前有两条广东电信的宽带，都是同城，只不过一个在中心城区西侧，另一个在中心城区东侧。
东侧那条宽带比较正常，哪怕我不指定前缀长度，分配给我的 IPv6 地址前缀基本上都是 /60 ，以前还出现过分配 /56 。
而西侧那条宽带就很奇怪，只要我不指定前缀长度，它就一定给我分配 /64 ，导致没办法进一步自动划分子网。于是我只好用软路由发送前缀长度提示，这样才能让该区电信给我分配 /60 的前缀（在软路由内我是设置成发送 /56 的提示，目的是让该区电信设备给我返回此线路支持的最短前缀）

@VZMZZZ
@viberconnection
除了“免费 ARP”，还有另一个没那么怪的称呼：无故 ARP

当然了，最精准的应该还是维基百科采纳的通用翻译：无回报 ARP （这个翻译也能 google 得到相关资料）

确实最好还是针对每个 arch 以及每个 libc / libstdc++ (libc++) 分别编译。

libc 不仅仅有 glibc ，还有 musl

这是大坑，尽管默认使用 musl 的发行版并不多

@Neur2n 还不至于复杂到需要文档的地步吧
目前位于 Readme 的介绍就是完整的功能介绍了，可以配置的选项都写在了表格内

@Neur2n udphop 并非一定要 VPS ，我自己就没把 udphop 放在 VPS 上，而是放在路由器（服务端模式）和自己的电脑（客户端模式）

@lly8666 前几天更新了静态链接版本，可以再试试

@pagxir
@ec0

好了，这下搞清楚原因在哪了，确实是 GCC 的锅。
我在 Debian 测试版运行了一次 apt upgrade ，把所有能够更新的都更新一遍，其中就包括 GCC 。我记得应该有两个月没更新过了。

升级完成后，原本 GCC 10 会失败的命令
c++ aes.cpp -I./include/botan-2 -lstdc++ -L:./lib/ -lbotan-2 -static
在最新版 GCC 12.2.0-9 一次性成功

至于是什么 bug 就懒得查了。我只能说，GCC 真不是省油的灯。

Debian 10 、11 、最新的测试版，试了我很多次，都是一堆 undefined reference ，心累

@pagxir 首先可以肯定的是，botan 库在编译的时候已经附带 index 的选项，这是 Botan 自己生成的 makefile 开头：
CXX = g++
LINKER = $(CXX)
AR = ar
AR_OPTIONS = crs
PYTHON_EXE = /usr/bin/python3


为了简单起见，就以我给 Botan 作者贴出的 aes.cpp 做编译。

第一次，用 Debian 自带软件包管理器安装出来的 Botan：
c++ -lbotan-2 -I/usr/include/botan-2 -lstdc++ -lpthread aes.cpp
c++ -I/usr/include/botan-2 -lbotan-2 -lstdc++ -lpthread aes.cpp
c++ -I/usr/include/botan-2 -lstdc++ -lbotan-2 -lpthread aes.cpp
c++ -I/usr/include/botan-2 -lstdc++ -lpthread -lbotan-2 aes.cpp

c++ -static -lbotan-2 -I/usr/include/botan-2 -lstdc++ -lpthread aes.cpp
c++ -static -I/usr/include/botan-2 -lbotan-2 -lstdc++ -lpthread aes.cpp
c++ -static -I/usr/include/botan-2 -lstdc++ -lbotan-2 -lpthread aes.cpp
c++ -static -I/usr/include/botan-2 -lstdc++ -lpthread -lbotan-2 aes.cpp
c++ -static -I/usr/include/botan-2 -lstdc++ -lpthread aes.cpp -lbotan-2

以上命令全部失败，undefined reference 一堆。唯一成功的就是作者给出的命令
c++ -I/usr/include/botan-2 -lstdc++ -lpthread aes.cpp -lbotan-2
这样会编译出动态库版本，而不是静态库版本。

接着用我下载 Botan 源码手动编译的版本：
c++ -L:./lib/libbotan-2.a -I./include/botan-2 -lstdc++ -lpthread aes.cpp
c++ -I./include/botan-2 -L:./lib/libbotan-2.a -lstdc++ -lpthread aes.cpp
c++ -I./include/botan-2 -lstdc++ -L:./lib/libbotan-2.a -lpthread aes.cpp
c++ -I./include/botan-2 -lstdc++ -lpthread aes.cpp -L:./lib/libbotan-2.a

c++ -static -L:./lib/libbotan-2.a -I./include/botan-2 -lstdc++ -lpthread aes.cpp
c++ -static -I./include/botan-2 -L:./lib/libbotan-2.a -lstdc++ -lpthread aes.cpp
c++ -static -I./include/botan-2 -lstdc++ -L:./lib/libbotan-2.a -lpthread aes.cpp
c++ -static -I./include/botan-2 -lstdc++ -lpthread aes.cpp -L:./lib/libbotan-2.a

以上命令依旧全部失败，仍然还是 undefined reference 一大堆。

GCC 的版本：
$ c++ --version
c++ (Debian 10.2.1-6) 10.2.1 20210110
Copyright (C) 2020 Free Software Foundation, Inc.

上面那个好像失效了，再放一个：
https://temp.sh/CAfSj/botan2.19.3.log

@lixile Log 太长，放在临时网盘了：
https://file.io/SSNkzdCvnASo

@zoumouse 就以我给 Botan 提 issue 时的测试代码为例
https://github.com/randombit/botan/issues/3085

即使加了 -static ，还是一样报错。

@changnet 十分奇怪的是，我自己编译 Botan 源码自己链接，还是不行（ Debian 11 和 Debian 最新测试版），但 alpine 用户可以。我按照 alpine 用户给出的经验操作去试，报错信息依然爆了一堆。

而同样都是 .a 静态编译，clang 工具链一下子就完成了，非常顺畅； VS 解决起来相对也是好一点，vcpkg 同样可以指定编译成动态库还是静态库，我是两种库都备好，这样就可以根据自己的设置选择正确的版本，选对了基本都能编译成功。

目前 clang 唯一不足的是对于 C++新标准的完善度相对较落后，其他方面我觉得比 GNU 好得多
