php找不到库,64位系统下编译PHP找不到库文件问题

最近在64位系统上编译5.4.5版的PHP时&＃xff0c;遇到报以下错&＃xff1a;

checking for DSA_get_default_method in -lssl... yes

checking for X509_free in -lcrypto... yes

checking for pkg-config... /usr/bin/pkg-config

configure: error: Cannot find OpenSSL&＃39;s libraries

指定的编译参数&＃xff1a;

./configure \

--prefix&＃61;/usr/local/services/php-5.4.5 \

--with-config-file-path&＃61;/usr/local/services/php-5.4.5/etc \

--enable-fpm \

--enable-mbstring \

--enable-soap \

--enable-sockets \

--enable-zip \

--with-curl&＃61;/usr \

--with-mysql&＃61;mysqlnd \

--with-mysqli&＃61;mysqlnd \

--with-pdo-mysql&＃61;mysqlnd \

--with-gd \

--with-jpeg-dir&＃61;/usr \

--with-png-dir&＃61;/usr \

--with-zlib-dir&＃61;/usr \

--with-freetype-dir&＃61;/usr \

--with-openssl&＃61;/usr

找不到openssl的库文件&＃xff0c;但我明明有安装openssl-devel的&＃xff0c;很奇怪&＃xff0c;网上搜了一下&＃xff0c;发现有很多朋友&＃xff0c;遇到了同样的问题&＃xff0c;有些人说--with-openssl不指定路径可解决&＃xff0c;尝试了一下&＃xff0c;的确编译通过了&＃xff0c;但想不通&＃xff0c;Why?后来&＃xff0c;又搜了一些文章来看&＃xff0c;终于找出问题的根源&＃xff1a;安装的系统是64位的&＃xff0c;而64位的用户库文件默认是在/usr/lib64&＃xff0c;而我编译的时候&＃xff0c;没有指定--with-libdir&＃61;lib64&＃xff0c;而编译脚本默认是lib&＃xff0c;这当然是找不到的。

将编译参数更改为&＃xff1a;

./configure \

--prefix&＃61;/usr/local/services/php-5.4.5 \

--with-config-file-path&＃61;/usr/local/services/php-5.4.5/etc \

--enable-fpm \

--enable-mbstring \

--enable-soap \

--enable-sockets \

--enable-zip \

--with-curl&＃61;/usr \

--with-mysql&＃61;mysqlnd \

--with-mysqli&＃61;mysqlnd \

--with-pdo-mysql&＃61;mysqlnd \

--with-gd \

--with-jpeg-dir&＃61;/usr \

--with-png-dir&＃61;/usr \

--with-zlib-dir&＃61;/usr \

--with-freetype-dir&＃61;/usr \

--with-openssl&＃61;/usr \

--with-libdir&＃61;lib64

问题解决。
