Question

我想在CentOS 7上为我的路由器（netcore q3，中国制造）交叉编译shadowsocks。所以我得到了crosstools-ng，我ssh到路由器，并得到以下信息（路由器在番茄固件1.28上.0000 MIPSR2-131 K26 Max by shibby），我使用How to build a cross compiler for your Raspberry Pi作为参考

$less /proc/cpuinfo
system type             : Broadcom BCM53572 chip rev 1 pkg 8
processor               : 0

BogoMIPS                : 149.50
cpu MHz                 : 300

tlb_entries             : 32

shadow register sets    : 1
VCED exceptions         : not available
VCEI exceptions         : not available

unaligned_instructions  : 0

我还从/ lib

复制了一个.so文件

$ scp root@router:/lib/libc.so.0 .

[oglop@localhost tmp]$ readelf -h libc.so.0

路由器上的/ lib文件

root@unknown:/tmp/home/root# ls /lib
ld-uClibc.so.0                libgcc_s.so.1                 libutil.so.0
libc.so.0                     libm.so.0                     modules
libcrypt.so.0                 libnsl.so.0                   openvpn_plugin_auth_nvram.so
libdl.so.0                    libpthread.so.0

我可以从这两个获得所有信息吗？我应该选择哪个样品？所以从.so文件：

endianness : little endian
bitness: ?
abi: ?
target os: linux or bare-metal?
c library: glibc, musl or uClibc ?
...

我想我应该从mips-unknown-linux-uclibc开始并将其更改为小端？

[oglop@localhost tmp]$ ct-ng list-samples | grep mips
[G.X]   mips64el-n32-linux-uclibc
[G.X]   mips64el-n64-linux-uclibc
[G..]   mips-ar2315-linux-gnu
[G..]   mipsel-sde-elf
[G..]   mipsel-unknown-linux-gnu
[G..]   mips-malta-linux-gnu
[G..]   mips-unknown-elf
[G..]   mips-unknown-linux-uclibc

root@unknown:/tmp/home/root# cat /proc/version
Linux version 2.6.22.19 (root@tomato) (gcc version 4.2.4) #16 Tue Aug 4 00:16:31 CEST 2015

我试图弄清楚番茄使用的libc版本，但是

root@unknown:/tmp/home/root# /lib/libc.so.0 
Segmentation fault
root@unknown:/tmp/home/root# ldd --version
-sh: --version: not found

或者我可以从github上的番茄源shibby分支获得我需要的信息吗？

如何为我的路由器配置crosstools-ng样本以交叉编译工具链？
