狮身人面像在检查是否需要CFLAGS时的初始配置

Question

在Ubuntu (本地和Sphinx2.0.2)上安装Sphinx从未遇到任何问题。总是开箱而动。今天，我尝试在亚马逊EC2上的Ubuntu11.10上安装Sphinx2.0.3。

像往常一样，我已经开始使用"./configure -前缀=/home/sphinx“。所有的MySQL库和基本的包都就位了。

它只是没有通过“检查CFLAGS需要的p线程.”。下面是输出。也试过斯芬克斯2.0.2。不走运。

顺便说一句，您可以在“检查头文件”块下注意到，p线程头存在：

.....
checking pthread.h usability... yes
checking pthread.h presence... yes
checking for pthread.h... yes
....

我刚刚从这个ppa安装了11.10，没有问题：https://launchpad.net/~chris-lea/+archive/sphinxsearch

当然，如果您需要从源代码构建，这是没有好处的。
