apache安装报错undefined reference ssl                        


因为SSL发现漏洞，需要更换openssl-1.0.1g版本，编译安装后，apache httpd2.4.9提示还是旧版本的SSL，于是重新编译安装apache httpd，configure没有报错，但make的时候报如下错误：

检查发现是configure的时候没有添加--with-ssl=/usr/local/openssl-1.0.1g（重新编译安装后openssl的路径）的路径，添加后可解决以上报错的问题。


./configure --prefix=/home/apache-249  --enable-ssl --with-ssl=/usr/local/openssl-1.0.1g --with-pcre=/usr/local/pcre --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-so  --enable-rewrite --enable-modules=most --enable-mods-shared=most --enable-mpms-shared=all --with-mpm=event


如果不使用ssl，也可以在编译时候去掉--enable-ssl --with-ssl=/usr/local/openssl-1.0.1g，加上--disable-ssl 。
