如何在ubuntu下进行OpenSSL的API编程？？？

lcgkm

我在ubuntu上已经安装好了OpenSSL

1. 
   
2. $ apt-cache search libssl | grep SSL
   
3. libssl0.9.7 - SSL shared libraries
   
4. cl-plus-ssl - A simple Common Lisp interface to OpenSSL
   
5. libssl-ocaml - OCaml bindings for OpenSSL
   
6. libssl-ocaml-dev - OCaml bindings for OpenSSL
   
7. libssl-dev - SSL development libraries, header files and documentation
   
8. libssl0.9.8 - SSL 共享库
   

复制代码

而我在使用eclipse-CDT编程过程中已经加入了头文件，函数在eclipse中着色也没问题，可总是报错！
错误如下：
**** Build of configuration Debug for project BIO ****

make: *** [BIO] 错误 1

我在猜想是否我没加入一些库文件？？？可应该加入什么库文件呢？怎么加？
小弟刚刚开始使用ubuntu，特请各位高手指教！！！

区分下声明和定义。

是。应加 libssl. 至于怎么加你就要看 Eclipse 的文档了。
