标题：安装PHP常见错误解决error: libjpeg.(a|so),error: libpng.(a|so) not found,error: Cannot find ldap 出处：沧海一粟 时间：Fri, 25 May 2012 09:41:33 +0000 作者：jed 地址：http://www.dzhope.com/post/919/ 内容： PHP的安装虽然有时候很简单,可是如果应用一多,我们安装起来就很头痛了!常见的就是PHP插件的安装问题最多了! 其实不管是你是Apache类的应用还是Nginx类的.PHP的安装都不是很简单,虽然网上很多configure,但是那不一定是适合你的,因为很多都直接关系着你的系统及系统版本和内核.那下面就进入正题 首先来一个最常见的就是configure: error: libjpeg.(a|so) not found 很多人都纳闷儿了,我都安装了的,为什么就找不到呢?找不到其实就应试想到它的搜索位置里面是没有的,要不然才不会说not found 原因是我们大部分一些软件只要rpm -qa | grep *** 这时下面就有两个重复的的软件 [root@GFS_Server php-5.2.13]# rpm -qa | grep jpeg libjpeg-6b-33 libjpeg-6b-33 libjpeg-devel-6b-33 32位和64位的都装了。你可以强制删除两个包，再重装64位的包。rpm --allmatches --nodeps这种方法真是损系统又损你.有时候强制执行的东西也会随便把lib中的一些包给强制删了..所以我认为不建议这么做,重复就让它重复吧,没关系的! 要解决问题就是它没找到,我安装了的,那我得去找找看它到底是放那里去了 [root@GFS_Server php-5.2.13]# updatedb [root@GFS_Server php-5.2.13]# locate libjpeg.so /usr/lib64/libjpeg.so.62 /usr/lib64/libjpeg.so.62.0.0 /usr/lib64/libjpeg.so /usr/lib/libjpeg.so [root@GFS_Server php-5.2.13]# locate libjpeg.a /usr/lib64/libjpeg.a /data0/software/jpeg-6b/libjpeg.a [root@GFS_Server php-5.2.13]# 我们在编译的时候经常看到一个库的文件,一般就是以*.a,*.so等名字的,尝试的搜索搜索,不行就模糊搜索! 通过上面的搜索其实就知道一些原因了,configure一般的搜索编译路径为/usr/lib/下,因为php默认就在/usr/lib/下找相关库文件,而x64机器上是在:/usr/lib64.这时你就可以直接把需要的库文件从/usr/lib64中拷贝到/usr/lib/中去就可以了. 那么记得要在configure前执行如下的命令: cp -frp /usr/lib64/libjpeg.* /usr/lib/ usr/bin/install: cannot create regular file `/usr/local/man/man1/cjpeg.1': No such file or directory make: *** [install] Error 1 提示找不到目录。既然电脑找不到，咱们人脑可以找嘛，自己先创建先 mkdir /usr/local/man mkdir /usr/local/man1 创建完了再来 make install (没报错就成功) configure: error: libjpng.(a|so) not found 其实也是和刚才的一样. cp -frp /usr/lib64/libpng* /usr/lib/ configure: error: Cannot find ldap libraries in /usr/lib. cp -frp /usr/lib64/libldap* /usr/lib/ 类似错误很多,方法也很多,我们得灵活应变,具体问题具体分析! 另外附一些常见的configure错误列表供参考: configure: error: No curses/termcap library found 网上有的说法是： --with-named-curses-libs=/usr/lib/libncursesw.so.5 其实是不对的，虽然能解决configure的错误，但是make的时候会提示错误，正确的做法应该是 yum -y install ncurses-devel debian: apt-get install libncurses5-dev configure: error: xml2-config not found yum -y install libxml2-devel debian:apt-get install libxml2-dev configure: error: Cannot find OpenSSL's yum -y install openssl-devel configure: error: libjpeg.(a|so) not found yum -y install gd yum -y install gd-devel debian:apt-get install libjpeg-dev configure: error: libpng.(a|so) not found. apt-get install libpng12-dev configure: error: cannot find output from lex; giving up yum -y install flex configure: error: mod_deflate has been requested but can not be built due to prerequisite failures yum -y install zlib-devel openssl-devel debian:apt-get install zlib1g-dev configure: error: libXpm.(a|so) not found. apt-get install libxpm-dev onfigure: error: freetype.h not found. apt-get install libfreetype6-dev configure: error: ...No recognized SSL/TLS toolkit detected apt-get install libssl-dev 1) Configure: error: xml2-config not found.
