CentOS6.5上给curl安装ssl时错误解决

1 在CentOS上使用PHP的curl访问HTTPS页面时，出现错误“Protocol https not supported or disabled in libcurl”。

表示curl未启用https，需要重新编译php所使用的curl库。

cd curl-7.31.0
./configure --prefix=/home/www/thirdlib/curl --with-ssl=/ueidc/openssl

出现错误提示：

checking for SSL_connect in -lssl... no
checking for ssl with RSAglue/rsaref libs in use... checking for SSL_connect in -lssl... (cached) no
configure: error: OpenSSL libs and/or directories were not found where specified!

是因为安装openssl时没启用shared选项，没有生成共享库

2 问题：

/usr/bin/ld: warning: libcrypto.so.1.0.0, needed by ../lib/.libs/libcurl.so, not found (try using -rpath or -rpath-link)

解决方式：

env LDFLAGS=-R/home/www/thirdlib/openssl/lib ./configure --prefix=/home/www/thirdlib/curl --with-ssl=/home/www/thirdlib/openssl

3 ./configure --with-php-config=/home/www/php/bin/php-config --with-curl=/home/www/thirdlib/curl
