1. 交叉编译环境：
export ARCH=arm
export SUBARCH=arm
export PATH=/opt/FriendlyARM/toolschain/4.5./bin:$PATH
export CROSS_COMPILE=/opt/FriendlyARM/toolschain/4.5./bin/arm-linux-
2. 安装依赖环境：
sudo aptitude install zlib1g-dev libssl-dev
3. 编译 zlib for ARM: 版本[zlib-1.2.8.tar.gz]
./configure --prefix=/opt/FriendlyARM/zlib
make -j4 -e \
"CC=arm-linux-gcc" \
"AR=arm-linux-ar" \
"CPP=arm-linux-gcc -E" \
"LDSHARED=arm-linux-gcc -shared -Wl,-soname,libz.so.1,--version-script,zlib.map"
make install # 要求/opt目录的所有者为当前用户
4. 编译 openssl: 版本[openssl-1.0.1e.tar.gz]
unset CROSS_COMPILE #必须执行的命令！
./Configure --prefix=/opt/FriendlyARM/openssl os/compiler:arm-linux-gcc
make -j4
make install
5. 编译 openssh: openssh-6.3p1.tar.gz
./configure --prefix=/opt/FriendlyARM/openssh \
--host=arm-linux \
--with-zlib=/opt/FriendlyARM/zlib \
--with-ssl-dir=/opt/FriendlyARM/openssl \
CC=arm-linux-gcc
make -j4 # 不需要make install，安装不上的!!
>>在PC打包ssh成为一个tar包：
#!/bin/sh -
tmpdir=tmp_arm
prefix=/opt/FriendlyARM/openssh
mkdir $tmpdir
mkdir -p $tmpdir/$prefix/etc
mkdir -p $tmpdir/$prefix/bin
mkdir -p $tmpdir/$prefix/etc
mkdir -p $tmpdir/$prefix/libexec
mkdir -p $tmpdir/$prefix/sbin
ssh-keygen -t rsa -f ssh_host_rsa_key -N ""
ssh-keygen -t dsa -f ssh_host_dsa_key -N ""
ssh-keygen -t ecdsa -f ssh_host_ecdsa_key -N ""
cp ssh_host_*_key $tmpdir/$prefix/etc/
cp scp sftp ssh ssh-add ssh-agent ssh-keygen ssh-keyscan $tmpdir/$prefix/bin/
cp moduli ssh_config sshd_config $tmpdir/$prefix/etc/
cp sftp-server ssh-keysign $tmpdir/$prefix/libexec/
cp sshd $tmpdir/$prefix/sbin/
cd $tmpdir
tar zcf ssh_arm.tgz /opt/FriendlyARM/openssl /opt/FriendlyARM/zlib *
>>把tar包拷贝至ARM板后，安装过程：
#!/bin/sh -
# run on arm
tar zxf ssh_arm.tgz -C /
echo 'PATH=/opt/FriendlyARM/openssh/bin:/opt/FriendlyARM/openssh/sbin:$PATH' >> /etc/profile
echo 'sshd:x:74:74:Privilege-separated SSH:/var/empty/sshd:/sbin/nologin' >> /etc/passwd
source /etc/profile
>> 效果展示：先在ARM板上执行 /opt/FriendlyARM/openssh/sbin/sshd
这表明已经成功通过ssh连接至ARM开发板了。
