交叉编译：zlib，openSSL，openSSH

1. 编译zlib

wget https://www.zlib.net/zlib-1.2.12.tar.gz
# 编译命令
export CC=arm-fullhanv3-linux-uclibcgnueabi- ./configure --prefix=/home/hxf0223/tmp/ssh/target
make -j && make install

2. 编译openSSL

wget https://github.com/openssl/openssl/archive/refs/tags/openssl-3.0.2.tar.gz
# 编译命令
./Configure linux-generic32 no-asm shared no-async --prefix=/home/hxf0223/tmp/ssh/target/ CROSS_COMPILE=arm-fullhanv3-linux-uclibcgnueabi- CC=gcc

3. 编译openSSH

wget https://mirrors.aliyun.com/pub/OpenBSD/OpenSSH/portable/openssh-9.0p1.tar.gz
# 编译命令
./configure --host=arm-fullhanv3-linux-uclibcgnueabi --enable-static LIBS="pthread" --with-libs --with-zlib=/home/hxf0223/tmp/ssh/target --with-ssl-dir=/home/hxf0223/tmp/ssh/target --disable-etc-default-login CC=arm-fullhanv3-linux-uclibcgnueabi-gcc AR=arm-fullhanv3-linux-uclibcgnueabi-ar
make -j # 不执行install

4. 打包

grep -rIL .  # 找出bin档，并复制到target/bin目录

• 移植openssh到arm-linux
• Build OpenSSH with static linked zlib and OpenSSL libraries
