配置 dropbear 失败：缺少 zlib

Question

我已经有一个交叉编译的 zlib:

path/to/zlib/install/
├── include
│   ├── zconf.h
│   └── zlib.h
├── lib
│   ├── libz.a
│   ├── libz.so -> libz.so.1.2.11
│   ├── libz.so.1 -> libz.so.1.2.11
│   ├── libz.so.1.2.11
│   └── pkgconfig
│       └── zlib.pc
└── share
    └── man
        └── man3
            └── zlib.3

但是当我运行 configure 的 dropbear 时，控制台显示 configure: error: *** zlib missing - install first or check config.log ***:

CC=arm-linux-gcc \
./configure \
--host=arm-linux \
--with-zlib=path/to/zlib/install

这是 config.log 附近的一部分错误：

已解决。

我的编译器不支持 SSP。使用 --disable-harden 来禁用 SSP。

非常感谢@nhatnq。
