ubuntu下交叉编译lftp

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)
/opt/hisi-linux/x86-arm/arm--linux/bin/../lib/gcc/arm-linux-gnueabi/4.8.3/../../../../arm-linux-gnueabi/bin/ld: warning: libhogweed.so.4, 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
