最近在64位系统上编译5.4.5版的PHP时,遇到报以下错:
- 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"s libraries
指定的编译参数:
- ./configure
- --prefix=/usr/local/services/php-5.4.5
- --with-config-file-path=/usr/local/services/php-5.4.5/etc
- --enable-fpm
- --enable-mbstring
- --enable-soap
- --enable-sockets
- --enable-zip
- --with-curl=/usr
- --with-mysql=mysqlnd
- --with-mysqli=mysqlnd
- --with-pdo-mysql=mysqlnd
- --with-gd
- --with-jpeg-dir=/usr
- --with-png-dir=/usr
- --with-zlib-dir=/usr
- --with-freetype-dir=/usr
- --with-openssl=/usr
找不到openssl的库文件,但我明明有安装openssl-devel的,很奇怪,网上搜了一下,发现有很多朋友,遇到了同样的问题,有些人说--with-openssl不指定路径可解决,尝试了一下,的确编译通过了,但想不通,Why?后来,又搜了一些文章来看,终于找出问题的根源:安装的系统是64位的,而64位的用户库文件默认是在/usr/lib64,而我编译的时候,没有指定--with-libdir=lib64,而编译脚本默认是lib,这当然是找不到的。将编译参数更改为:
- ./configure
- --prefix=/usr/local/services/php-5.4.5
- --with-config-file-path=/usr/local/services/php-5.4.5/etc
- --enable-fpm
- --enable-mbstring
- --enable-soap
- --enable-sockets
- --enable-zip
- --with-curl=/usr
- --with-mysql=mysqlnd
- --with-mysqli=mysqlnd
- --with-pdo-mysql=mysqlnd
- --with-gd
- --with-jpeg-dir=/usr
- --with-png-dir=/usr
- --with-zlib-dir=/usr
- --with-freetype-dir=/usr
- --with-openssl=/usr
- --with-libdir=lib64
问题解决。
