今天在Ubuntu 11.10编译php-5.2.17的时候出现如下的错误：
- php-5.2.17/ext/openssl/xp_ssl.c:357: undefined reference to `SSLv2_server_method'
- php-5.2.17/ext/openssl/xp_ssl.c:337: undefined reference to `SSLv2_client_method'
- collect2: ld returned 1 exit status
- make: *** [sapi/cgi/php-cgi] 错误 1
这个需要一个补丁禁用openssl的SSLv2_client_method，方法如下：
- cd php-5.2.17/
- wget https://www.centos.bz/wp-content/uploads/2012/06/debian_patches_disable_SSLv2_for_openssl_1_0_0.patch
- patch -p1 < debian_patches_disable_SSLv2_for_openssl_1_0_0.patch
然后再重新编译php
- make clean
- make && make install
