上边的加粗蓝色字体为错误信息，请问是什么原因？

[白菜帮主]

另，我的zlib安装在默认系统目录，而不是指定在单的独安装目录里。

你看一下你的/usr/local/jpeg6/目录中是否有libjpeg.a或者libjpeg.so文件，如果没有就不行，如果有相似的可以建立一个link文件

[cloudflashes]

libjpeg.so库找不到。看一下你/usr/lib/ 或者/usr/lib64下有没有。
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

[白菜帮主]

已经解决。
方法：
jpeg6卸载后，再重装一遍即可。
