I also copied a compiled minivtun from other Linux distro, and tried to run on debian 9, unfortunately it also failed.
user@debian:~/minivtun$ ./minivtun -h
./minivtun: error while loading shared libraries: libcrypto.so.10: cannot open shared object file: No such file or directory

debian 9 上的 openssl 是版本 1.1 对吧？ 在 1.1 里面把结构体都隐藏了，必须改用 指针的方式。 你用 openssl 1.0 的版本重新编译下就行了
