一.背景:
lftp依赖于ncurses,readline和gnutls
二.准备工作
2.1交叉编译ncurses
2.1.1获取ncurses源码
wget ftp://ftp.invisible-island.net/ncurses/ncurses.tar.gz
2.1.2解压
tar xvf ncurses.tar.gz
2.1.3配置以生成Makefile
./configure CC=arm-linux-gnueabi-gcc --host=arm-linux-gnueabi --prefix=/home/jello/ncurses-5.9/__install
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install --with-shared
2.1.4 编译
make
2.1.5 安装
make install
2.2 交叉编译readline
2.2.1获取readline源码
wget ftp://ftp.cwru.edu/pub/bash/readline-6.3.tar.gz
2.2.2 解压
tar xvf readline-6.3.tar.gz
2.2.3生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install
2.2.4 编译
make
2.2.5安装
make install
2.3 交叉编译gnutls
2.3.1 获取gnutls源码
git clone https://gitlab.com/gnutls/gnutls.git
cd gnutls
git submodule update --init
git checkout master
2.3.2 生成configure
autoreconf
2.3.2.1出现以下错误提示
configure.ac: error: required file 'build-aux/ylwrap' not found
configure.ac: 'automake --add-missing' can install 'ylwrap'
autoreconf: automake failed with exit status: 1
解决方案:
automake --add-missing
2.3.2.2创建编译目录，防止污染源码
mkdir build
2.3.2.3 切换到编译目录
cd build
2.3.3 生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install
2.3.3.1 出现以下错误:
configure: error:
***
*** Libnettle 3.1 was not found.
解决方案:
安装版本号为3.1的nettle库(加密库)
2.3.3.1.1 获取nettle库源码
wget ftp.gnu.org/gnu/nettle/nettle-3.1.tar.gz
2.3.3.1.2 解压nettle库源码
tar xvf nettle-3.1.tar.gz
2.3.3.1.3 切换到源码目录下
cd nettle-3.1
2.3.3.1.4 创建编译目录
mkdir build
2.3.3.1.5 切换到编译目录
cd build
2.3.3.1.6 生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install
2.3.3.1.7 编译源码
make -j4
2.3.3.1.8 安装
make install
2.3.4 重新生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install NETTLE_CFLAGS=-I/home/jello/nettle-3.1/build/__install/include NETTLE_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lnettle"
2.3.4.1 出现以下错误:
*** Libhogweed (nettle's companion library) was not found. Note that you must compile nettle with gmp support.
解决方案:
2.3.4.1.1 在编译nettle时加上gmp库
前情提要:
nettle 是symmetric algorithms
hogweed 是public-key algorithms
nettle库和hogweed库组合起来就是Nettle low-level cryptographic library
2.3.4.1.2 重新交叉编译nettle
2.3.4.1.2.1 切换到nettle源码目录下并将之前编译的内容全部清除
cd nettle-3.1 && rm -rf build
2.3.4.1.2.2 创建编译目录
mkdir build
2.3.4.1.2.3 切换到编译目录
cd build
2.3.4.1.2.4 生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install CFLAGS=-I/home/jello/gmp-6.1.2/build/__install/include LDFLAGS=-L/home/jello/gmp-6.1.2/build/__install/lib LIBS=-lgmp (gmp库的编译方法在后面)
2.3.4.1.2.5 编译源码
make -j4
2.3.4.1.2.6 安装
make install
2.3.5 再次生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install NETTLE_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" NETTLE_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lnettle" HOGWEED_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" HOGWEED_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lhogweed"
2.3.5.1 提示以下错误:
Libtasn1 4.9 was not found. To use the included one, use --with-included-libtasn1
解决方案:
2.3.5.1.1 将--with-included-libtasn1这个选项加入
2.3.6 重新生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install NETTLE_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" NETTLE_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lnettle" HOGWEED_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" HOGWEED_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lhogweed" --with-nettle-mini --with-included-libtasn1
出现以下错误提示:
Libunistring was not found. To use the included one, use --with-included-unistring
解决方案:
2.3.6.1 将--with-included-unistring这个选项加入
2.3.7 重新生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install NETTLE_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" NETTLE_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lnettle" HOGWEED_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" HOGWEED_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lhogweed" --with-nettle-mini --with-included-libtasn1 --with-included-unistring
出现以下错误:
checking for unbound library... no
configure: WARNING:
***
*** libunbound was not found. Libdane will not be built.
***
checking for P11_KIT... no
configure: error:
***
*** p11-kit >= 0.23.1 was not found. To disable PKCS #11 support
*** use --without-p11-kit, otherwise you may get p11-kit from
*** http://p11-glue.freedesktop.org/p11-kit.html
解决方案:
2.3.7.1 加入两个选项--disable-libdane和-without-p11-kit
2.3.7.1.1 第一个选项就是不要编译libdane库，第二个选项就是不要加入p11-kit库
2.3.8 重新生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install NETTLE_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" NETTLE_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lnettle" HOGWEED_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" HOGWEED_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lhogweed" --with-included-libtasn1 --with-included-unistring --disable-libdane -without-p11-kit
出现以下错误：
checking that generated files are newer than configure... done
configure: creating ./config.status
config.status: error: cannot find input file: `src/libopts/Makefile.in'
2.3.8.1 换成release版本试试,目前使用的是开发版本
2.3.9 获取release版本
wget ftp://ftp.gnutls.org/gcrypt/gnutls/v3.5/gnutls-3.5.17.tar.xz
2.3.10 解压
tar xvf gnutls-3.5.17.tar.xz
2.3.11 切换到源码目录
cd gnutls-3.5.17
2.3.12 创建编译目录
mkdir build
2.3.13 生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install NETTLE_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" NETTLE_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lnettle" HOGWEED_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" HOGWEED_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lhogweed" --with-included-libtasn1 --with-included-unistring --disable-libdane --without-p11-kit
2.3.14 编译
make -j4
出现以下错误:
In file included from ../../../lib/nettle/pk.c:41:0:
../../../lib/nettle/int/dsa-fips.h:27:17: fatal error: gmp.h: No such file or directory
#include <gmp.h>
^
compilation terminated.
Makefile:1474: recipe for target 'pk.lo' failed
解决方案:
从以上错误可知gnutls还依赖于gmp库，所以解决方案是编译好gmp库
2.3.14.1 获取gmp库
wget https://gmplib.org/download/gmp/gmp-6.1.2.tar.lz
2.3.14.2 解压gmp-6.1.2.tar.lz
lunzip gmp-6.1.2.tar.lz (需要安装lunzip这个软件,ubuntu下的安装方法: sudo apt-get install lunzip)
tar xvf gmp-6.1.2.tar
2.3.14.3 切换到解压后的源码目录
cd gmp-6.1.2
2.3.14.4 创建编译目录build
mkdir build
2.3.14.5 切换到build目录
cd build
2.3.14.6 生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install
2.3.14.7 编译
make
2.3.14.8 安装
make install
2.3.15 重新编译gnutls,生成Makefile (需要删除之前gnutls的build目录里的内容)
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install GMP_CFLAGS="-I/home/jello/gmp-6.1.2/build/__install/include" GMP_LIBS="-L/home/jello/gmp-6.1.2/build/__install/lib -lgmp" NETTLE_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" NETTLE_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lnettle" HOGWEED_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" HOGWEED_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lhogweed" --with-included-libtasn1 --with-included-unistring --disable-libdane --without-p11-kit
2.3.16 编译
make
此时会出现以下错误
eabi/4.8.3/../../../../armlinux-gnueabi/bin/ld: warning: libnettle.so.6, needed by ../lib/.libs/libgnutls.so, not found (try using -rpath or -rpath-link)

../lib/.libs/libgnutls.so: undefined reference to `nettle_aes192_encrypt@NETTLE_6'
../lib/.libs/libgnutls.so: undefined referenc
2.3.15 安装
三.交叉编译lftp
3.1获取lftp源码
wget http://lftp.yar.ru/ftp/lftp-4.8.3.tar.gz
3.2解压
tar xvf lftp-4.8.3.tar.gz
3.3生成Makefile
3.4安装
