openssl-1.1.0i
1.交叉编译openssl
./config no-asm -shared --prefix=/home/yiweijiao/openssh/ssl --cross-compile-prefix=/home/yiweijiao/toolchains/gcc-linaro-5.5.0-2017.10-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-
make
make install
2.交叉编译zlib
./configure --prefix=/home/yiweijiao/openssh/armzlib
修改makefile中的编译工具
make
make install
3.交叉编译openssh
./configure --host=arm-linux --prefix=/home/yiweijiao/openssh/install --with-libs --with-zlib=/home/yiweijiao/openssh/armzlib --with-ssl-dir=/home/yiweijiao/openssh/armssl --sysconfdir=/etc/ssh CC=/home/yiweijiao/toolchains/gcc-linaro-5.5.0-2017.10-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc AR=/home/yiweijiao/toolchains/gcc-linaro-5.5.0-2017.10-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-ar
make
make install
完成
