今天在Ubuntu 11.10编译php-5.2.17的时候出现 OPENSSL的错误问题
[zz]http://www.centos.bz/2012/06/openssl-undefined-reference-to-sslv2_client_method/

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 http://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
