在 Debian 7.0 中使用 libcrypto 使用 g++ 编译 c++ 程序

我在尝试使用 g++ 进行复制时遇到程序问题。这是命令：

root@server1:/home# g++ -o ssh2main ssh2main.cpp ssh2connect.cpp -static -lssh2 -L/usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0 -lcrypto -ldl -lz -Wno-write-strings;

这是我得到的输出：

/usr/bin/ld: cannot find -lcrypto
collect2: error: ld returned 1 exit status

我已经运行了apt-get libcrypt*，我看到它已安装。

root@server1: locate crypt

问题是，在CentOS 5.5, 5.7它可以毫无问题地工作。我做错了什么？我该如何解决这个问题？

谢谢。
