这是GNU链接工具的锅，就连Botan作者都无法解决。
我给Botan作者提了个Issue：randombit/botan#3085 ，问他怎样做才能静态链接。结果得到的回答是，请用动态链接库。

反倒是FreeBSD（用clang）和Windows（用MSVC）都可以正常使用静态链接的版本。

如果需要在Linux（以及NetBSD）使用静态链接，需要按照 https://botan.randombit.net/handbook/building.html 的 The Amalgamation Build 小节的介绍，制作出巨大无比的 botan_all.h 和botan_all.cpp 直接内嵌到项目中。
根据我的使用经验，步骤是：

第一步：

git clone https://github.com/randombit/botan.git
cd botan
./configure.py --amalgamation --disable-modules=pkcs11

第二步：

把生成好的两个 botan_all 复制到 udphop/src/shares

第三步：

修改 udphop/src/shares/CMakeLists.txt，找到

add_library(${THISLIB_NAME} STATIC share_defines.cpp)

修改为

add_library(${THISLIB_NAME} STATIC "share_defines.cpp" "botan_all.cpp")

第四步：

打开 udphop/src/shares/aead.hpp，把那一大串 #include <botan_XXXX> 删掉，改成 #include "botan_all.h"

第五步：

打开 udphop/CMakeLists.txt，把Linux那一行的 include_directories("/usr/include/botan-2") 删掉

这样就可以静态编译了。只是编译出来的二进制十分巨大，比FreeBSD的和Windows的都大得多。

十分巨大 是不是可以 strip --strip-debug 或者直接strip 再加upx打包

我这边自己尝试了一下，编译好动态的加载的udphop，把动态依赖库全部复制到当前目录，然后用patchelf修改成加载为当前路径的库

./patchelf --set-interpreter ./ld-linux-x86-64.so.2 udphop 
./patchelf --add-needed libc.so.6  udphop 
./patchelf --add-needed ./libc.so.6  udphop 
./patchelf --add-needed ./libstdc++.so.6  udphop 
./patchelf --add-needed ./libbotan-2.so.19  udphop 
./patchelf --add-needed ./libm.so.6  udphop 
./patchelf --add-needed ./libpthread.so.0  udphop 
./patchelf --add-needed ./libgcc_s.so.1  udphop 
./patchelf --add-needed ./libdl.so.2  udphop 
./patchelf --add-needed ./librt.so.1  udphop

已经成功编译静态链接的udphop：

1.一定要用 botan-2x的源码
2.查找udphop源码里的CMake files 添加 -static 编译参数

grep -r 'target_link_libraries' ./

On Modern CMake (3.x+ - target_link_libraries doc), you can apply the flag to specific targets, in this way:
target_link_libraries(your_target_name -static)

#original
-rw-rw-r-- 1 bhzhu bhzhu 23M 12月 3 10:53 udphop-static

#strip
-rw-rw-r-- 1 bhzhu bhzhu 7.6M 12月 3 10:53 udphop-static

#upx
-rwxrwxr-x 1 bhzhu bhzhu 2.2M 12月 3 10:53 udphop-static
