Ubuntu下openvpn源码安装
OpenVPN依赖OpenSSL库，用于加密，需要安装。LZO库，数据压缩用，不使用该库也没有关系。
OpenSSL的下载地址：http://www.openssl.org/
LZO的下载地址：http://www.oberhumer.com/opensource/lzo/
OpenVPN的下载地址：http://www.openvpn.net
1、./configure --with-lzo-headers=/usr/local/include --with-lzo-lib=/usr/local/lib --with-ssl-headers=/usr/local/ssl/include/ --with-ssl-lib=/usr/local/ssl/lib/
如果不带--with-ssl-headers的话，就会出现下面的错误
configure: checking for OpenSSL Crypto Library and Header files...
checking openssl/evp.h usability... no
checking openssl/evp.h presence... no
checking for openssl/evp.h... no
configure: error: OpenSSL Crypto headers not found
如果不带 --with-ssl-lib=/usr/local/ssl/lib/，则出现的错误是
configure: checking for OpenSSL Crypto Library and Header files...
checking openssl/evp.h usability... yes
checking openssl/evp.h presence... yes
checking for openssl/evp.h... yes
checking for EVP_CIPHER_CTX_init in -lcrypto... no
configure: error: OpenSSL Crypto library not found.
make ;make install
