安装mbedtls-devel 或 libmbedtls-devel 或 libmbedtls-deve即可

As the error said, you need mbed TLS library compiled first.

Nope.

check https://github.com/wongsyrone/lede-1/blob/master/package/libs/mbedtls/patches/999-tweak-config-for-shadowsocks.patch and apply this to your codebase

in case I change the patch later:

The root cause is some ciphers are disabled by default, just re-enable them to pass the configure stage.

Which file should i modify?

1558204459 on 6 Jun 2016

You can simply put the patch above into package/libs/mbedtls/patches or edit the patch exists via quilt yourself.

额，请教下：
我这边提示的是“MBEDTLS_CIPHER_MODE_CFB required”，但是我这里没有大神所说的目录“package/libs/mbedtls/patches ”。
我只在m4/mbedtls.m4 看到了相关语句：
“AC_MSG_CHECKING([whether mbedtls supports Cipher Feedback mode or not])
AC_COMPILE_IFELSE(
[AC_LANG_PROGRAM(
[[

include

  ]],
  [[

ifndef MBEDTLS_CIPHER_MODE_CFB

error Cipher Feedback mode a.k.a CFB not supported by your mbed TLS.

endif

  ]]
)],
[AC_MSG_RESULT([ok])],
[AC_MSG_ERROR([MBEDTLS_CIPHER_MODE_CFB required])]

)
”

那我应该怎么修改呢。。。

你需要重新编译mbedtls，默认OP的patch会关闭cfb，这样大部分加密都不可用了

wongsyrone on 25 Sep 2016

如果不会自己修改，复制 https://github.com/wongsyrone/lede-1/tree/master/package/libs/mbedtls 到 SDK的package目录里面，重新编译。那个补丁的意思是重新打开cfb, rc4, blowfish, camellia以及默认开启多线程支持，使用libpthread，musl的话是在libc里面，旧uclibc是单独的一个库。

Thanks for your detailed reply.
i just copyed https://github.com/wongsyrone/lede-1/tree/master/package/libs/mbedtls to SDK's package and typed “make V=99 package/mbedtls/compile” , and no errors.
then i re-compiled the shadowsocks-libev by "make V=99 package/shadowsocks-libev/openwrt/compile", but the console showed the same error "MBEDTLS_CIPHER_MODE_CFB required"
well, is there something i did wrong?

PS：今天被教育了，github是一个全球平台，我用中文询问回答，这样别国的人在遇到相同的问题，就没法直接获得答案，还要耽误大家的时间，我以后把答案改成英文。

应该是copy到feeds/base/package/libs/mbedtls吧，我直接拷贝到SDK目录下的package不可以。
