update: crosstool-ng 1.2.2 cross compile shadowsocks-libev 2.4.1 for 磊科q3 asus rt-n66u rt-n16

更新一下上一篇 CentOS 7下交叉编译tomato 1.2.8 v131路由器（磊科Q3）可以使用的shadowsocks 2.3.1 – 正/逆翻墙用

本文的内容已过时，请参考这篇: crosstool-ng 1.22.0 and shadowsocks 2.4.5 备忘录，有编译好的版本下载.

1. 编译crosstools-ng 1.2.2 最后lz使用的还是上一篇中的1.21

   sudo yum install -y gperf texinfo glib* libstdc++* help2man ncurses-devel makedepend
   git clone https://github.com/crosstool-ng/crosstool-ng.git
   cd crosstool-ng
   git checkout tags/crosstool-ng-1.22.0
   ./bootstrap 
   ./configure
   make && make install
   
   

2. 编译toolchain
   我的crosstools-ng 配置文件，uclibc 0.9.33配置文件

   前者是ct-ng list-samples之后找了最像的mips-unknown-linux-uclibc，选了他之后ct-ng arm-unknown-linux-gnueabi，然后手动改了一些选项ct-ng menuconfig，用的时候你得把uclibc的config文件的路径选成你自己的,lz打开了Save intermediate steps，万一你哪一步出错了你可以改下配置，从那里继续ct-ng LAST_SUCCESSFUL_STETP_NAME+；

   后者的配置文件是从buildroot里来的，make uclibc-menuconfig,

   # 可以打开配置页面，然后load lz的配置文件
   ct-ng menuconfig
   
   # build
   ct-ng build.4
   
   # 如果中间出错 又不想完全从头开始
   # 虽然配置文件里已经设了保存每步，也可以这样在命令行启用
   CT_DEBUG_CT_SAVE_STEPS=1 ct-ng build
   # 显示有哪些steps
   ct-ng list-steps
   # 从指定的step恢复
   RESTART=libc_start_files ct-ng build
   
   # 弄好以后
   export PATH=/home/oglop/x-tools/mipsel-unknown-linux-uclibc/bin:$PATH
   

   关键版本号

   GCC	Binutils	GMP	MPFR	ISL	MPC	expat	ncurses	uclibc
   5.2.0	2.25.1	6.0.0a	3.1.3	0.12.2	1.0.3	2.1.0	6.0	0.9.33.2

3. 编译zlib

   wget http://zlib.net/zlib-1.2.8.tar.gz
   cd zlib-1.2.8
   export PATH=/home/oglop/x-tools/mipsel-unknown-linux-uclibc/bin:$PATH
   tar xvf zlib-1.2.8.tar.gz 
   cd zlib-1.2.8/
   CC=mipsel-unknown-linux-uclibc-gcc CXX=mipsel-unknown-linux-uclibc-g++ AR=mipsel-unknown-linux-uclibc-ar RANLIB=mipsel-unknown-linux-uclibc-ranlib ./configure --prefix=/home/oglop/Downloads/zlib-install
   make && make install
   

4. 编译openssl

   git clone https://github.com/openssl/openssl.git
   git checkout tags/OpenSSL_1_0_2d
   CC=mipsel-linux-uclibc-gcc CXX=mipsel-linux-uclibc-g++ AR=mipsel-linux-uclibc-ar RANLIB=mipsel-linux-uclibc-ranlib ./Configure no-asm shared --prefix=/home/oglop/Downloads/openssl-install linux-mips32
   make && make install
   

5. 编译shadowsocks 2.4.1

   git clone https://github.com/shadowsocks/shadowsocks-libev.git
   cd shadowsocks-libev
   git checkout tags/v2.4.1
   CC=mipsel-unknown-linux-uclibc-gcc CXX=mipsel-unknown-linux-uclibc-g++ AR=mipsel-unknown-linux-uclibc-ar RANLIB=mipsel-unknown-linux-uclibc-ranlib ./configure --prefix=/home/oglop/Downloads/ss-install  --with-openssl=/home/oglop/Downloads/openssl-install --host=mipsel-uclibc-linux --with-zlib=/home/oglop/Downloads/zlib-install
   make V=99 && make install
   

   看看是不是dynamic的

   [oglop@t450s test]$ mipsel-unknown-linux-uclibc-ldd --root ~/x-tools/mipsel-unknown-linux-uclibc /home/oglop/Downloads/ss-install-static/bin/strip/ss-server
           libcrypto.so.1.0.0 not found
           libm.so.0 => /lib/libm.so.0 (0x8badf00d)
           libc.so.0 => /lib/libc.so.0 (0x8badf00d)
           ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x8badf00d)
           libz.so.1 not found

           libpthread.so.0 => /lib/libpthread.so.0 (0x8badf00d)
   

   瘦身一下

文件下载:
还是用上篇的ct-ng 1.21编译的
shadowsocks-libev_2.4.1_mipsel_OpenSSL_dynamic.tar.gz
mipsel-unknown-linux-uclibc-1.22.0.tar.gz
openssl-1.0.2d-dynamic-install.tar.gz

ps：lz在asus rt-n16上的tomato shibby版的v132上测试了下可用.
