一.背景:
lftp依賴於ncurses,readline和gnutls
二.准備工作
2.1交叉編譯ncurses
2.1.1獲取ncurses源碼
wget ftp://ftp.invisible-island.net/ncurses/ncurses.tar.gz
2.1.2解壓
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=$PWD/__install --with-shared
2.1.4 編譯
make
2.1.5 安裝
make install
2.2 交叉編譯readline
2.2.1獲取readline源碼
wget ftp://ftp.cwru.edu/pub/bash/readline-6.3.tar.gz
2.2.2 解壓
tar xvf readline-6.3.tar.gz
2.2.3生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install
2.2.4 編譯
make
2.2.5安裝
make install
2.3 交叉編譯gnutls
2.3.1 獲取gnutls源碼
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出現以下錯誤提示
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
解決方案:
automake --add-missing
2.3.2.2創建編譯目錄，防止污染源碼
mkdir build
2.3.2.3 切換到編譯目錄
cd build
2.3.3 生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install
2.3.3.1 出現以下錯誤:
configure: error:
***
*** Libnettle 3.1 was not found.
解決方案:
安裝版本號為3.1的nettle庫(加密庫)
2.3.3.1.1 獲取nettle庫源碼
wget ftp.gnu.org/gnu/nettle/nettle-3.1.tar.gz
2.3.3.1.2 解壓nettle庫源碼
tar xvf nettle-3.1.tar.gz
2.3.3.1.3 切換到源碼目錄下
cd nettle-3.1
2.3.3.1.4 創建編譯目錄
mkdir build
2.3.3.1.5 切換到編譯目錄
cd build
2.3.3.1.6 生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install
2.3.3.1.7 編譯源碼
make -j4
2.3.3.1.8 安裝
make install
2.3.4 重新生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install NETTLE_CFLAGS=-I/home/jello/nettle-3.1/build/__install/include NETTLE_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lnettle"
2.3.4.1 出現以下錯誤:
*** Libhogweed (nettle's companion library) was not found. Note that you must compile nettle with gmp support.
解決方案:
2.3.4.1.1 在編譯nettle時加上gmp庫
前情提要:
nettle 是symmetric algorithms
hogweed 是public-key algorithms
nettle庫和hogweed庫組合起來就是Nettle low-level cryptographic library
2.3.4.1.2 重新交叉編譯nettle
2.3.4.1.2.1 切換到nettle源碼目錄下並將之前編譯的內容全部清除
cd nettle-3.1 && rm -rf build
2.3.4.1.2.2 創建編譯目錄
mkdir build
2.3.4.1.2.3 切換到編譯目錄
cd build
2.3.4.1.2.4 生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$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庫的編譯方法在后面)
2.3.4.1.2.5 編譯源碼
make -j4
2.3.4.1.2.6 安裝
make install
2.3.5 再次生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install NETTLE_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" NETTLE_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lnettle" HOGWEED_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" HOGWEED_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lhogweed"
2.3.5.1 提示以下錯誤:
Libtasn1 4.9 was not found. To use the included one, use --with-included-libtasn1
解決方案:
2.3.5.1.1 將--with-included-libtasn1這個選項加入
2.3.6 重新生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$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
出現以下錯誤提示:
Libunistring was not found. To use the included one, use --with-included-unistring
解決方案:
2.3.6.1 將--with-included-unistring這個選項加入
2.3.7 重新生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install NETTLE_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" NETTLE_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lnettle" HOGWEED_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" HOGWEED_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lhogweed" --with-nettle-mini --with-included-libtasn1 --with-included-unistring
出現以下錯誤:
checking for unbound library... no
configure: WARNING:
***
*** libunbound was not found. Libdane will not be built.
***
checking for P11_KIT... no
configure: error:
***
*** p11-kit >= 0.23.1 was not found. To disable PKCS #11 support
*** use --without-p11-kit, otherwise you may get p11-kit from
*** http://p11-glue.freedesktop.org/p11-kit.html
解決方案:
2.3.7.1 加入兩個選項--disable-libdane和-without-p11-kit
2.3.7.1.1 第一個選項就是不要編譯libdane庫，第二個選項就是不要加入p11-kit庫
2.3.8 重新生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$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
出現以下錯誤：
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 換成release版本試試,目前使用的是開發版本
2.3.9 獲取release版本
wget ftp://ftp.gnutls.org/gcrypt/gnutls/v3.5/gnutls-3.5.17.tar.xz
2.3.10 解壓
tar xvf gnutls-3.5.17.tar.xz
2.3.11 切換到源碼目錄
cd gnutls-3.5.17
2.3.12 創建編譯目錄
mkdir build
2.3.13 生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install NETTLE_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" NETTLE_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lnettle" HOGWEED_CFLAGS="-I/home/jello/nettle-3.1/build/__install/include" HOGWEED_LIBS="-L/home/jello/nettle-3.1/build/__install/lib -lhogweed" --with-included-libtasn1 --with-included-unistring --disable-libdane --without-p11-kit
2.3.14 編譯
make -j4
出現以下錯誤:
In file included from ../../../lib/nettle/pk.c:41:0:
../../../lib/nettle/int/dsa-fips.h:27:17: fatal error: gmp.h: No such file or directory
#include <gmp.h>
^
compilation terminated.
Makefile:1474: recipe for target 'pk.lo' failed
解決方案:
從以上錯誤可知gnutls還依賴於gmp庫，所以解決方案是編譯好gmp庫
2.3.14.1 獲取gmp庫
wget https://gmplib.org/download/gmp/gmp-6.1.2.tar.lz
2.3.14.2 解壓gmp-6.1.2.tar.lz
lunzip gmp-6.1.2.tar.lz (需要安裝lunzip這個軟件,ubuntu下的安裝方法: sudo apt-get install lunzip)
tar xvf gmp-6.1.2.tar
2.3.14.3 切換到解壓后的源碼目錄
cd gmp-6.1.2
2.3.14.4 創建編譯目錄build
mkdir build
2.3.14.5 切換到build目錄
cd build
2.3.14.6 生成Makefile
../configure --host=arm-linux-gnueabi --prefix=$PWD/__install
2.3.14.7 編譯
make
2.3.14.8 安裝
make install
2.3.15 重新編譯gnutls,生成Makefile (需要刪除之前gnutls的build目錄里的內容)
../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 編譯
make
此時會出現以下錯誤
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 安裝
三.交叉編譯lftp
3.1獲取lftp源碼
wget http://lftp.yar.ru/ftp/lftp-4.8.3.tar.gz
3.2解壓
tar xvf lftp-4.8.3.tar.gz
3.3生成Makefile
3.4安裝
