交叉编译 kindle paperwhite dropbear

安装gcc

apt install gcc-arm-linux-gnueabi g++-arm-linux-gnueabi ccache  click
如果是ko
apt-get install gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf

下载dropbear和zlib

dropbear
zlib

编译zlib

下载解压zlib-1.2.11.tar.gz
tar xzvf zlib-1.2.11.tar.gz -C ~/download/dropbear-2018.76
cd ~/download/dropbear-2018.76/zlib-1.2.11
mdir build
./configure --prefix=~/download/dropbear-2018.76/zlib-1.2.11/build
vi Makefile
:%s/gcc/arm-linux-gnueabi-gcc/g

同理替换如下

CC=arm-linux-gnueabi-gcc
LDSHARED=arm-linux-gnueabi-gcc -shared -Wl,-soname,libz.so.1,--version-script,zlib.map
CPP=arm-linux-gnueabi-gcc -E
AR=arm-linux-gnueabi-ar
RANLIB=arm-linux-gnueabi-ranlib

然后make 就好了
~/download/dropbear-2018.76/zlib-1.2.11/build有3个文件夹。。
include  lib  share

编译dropbear

cd ~/download/dropbear-2018.76
./configure CC=arm-linux-gnueabi-gcc --build=i686-linux    --host=arm-linux --target=arm-linux --with-zlib=/root/download/dropbear-2018.76/zlib-1.2.11
make

传到kindle试试。。
