【问题描述】：
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 dropbear 的configure 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 的一部分，附近有错误：

【问题讨论】：
-
缺少
-lssp_nonshared and -lssp导致编译失败 -
@nhatnq 感谢您的回复。我不这么认为。因为
checking for deflate in -lz之前的其他检查也显示ld: cannot find -lssp_nonshared&ld: cannot find -lssp，但不会导致失败。 -
你能用
deflate上面的代码创建类似的例子并尝试在外面编译吗？只需执行configure脚本所做的操作即可。想看编译器的输出 -
相同的结果：
ld: cannot find -lssp_nonshared&ld: cannot find -lssp。其他检查是可选的（例如 crypt）。所以他们不会导致失败。但是 zlib 是必需的。我对吗？ @nhatnq
