我开始装的是slackware 10,内核是2.42，把内核升级到2.6.9，然后又下了Slackware站点上编译过的的glibc-2.3.3包，安装后，发现glibc-2.3.3已经成功被安装上，但是Slackware的维护者没有把NPTL编译进他发布的glibc-2.3.3包中，现在我的一个程序急需要在NPTL下测试，请各位高手帮忙告诉我我现在该怎么办才能让我的gligc-2.3.3支持NPTL？万分感谢！！！

我个人看法是：这个glibc-2.3.3是在 2.4.27上编译的。如果要让glibc-2.3.3支持NPTL，只有自己编译安装glibc了，如果要这样，怎么卸载我目前已经安装的glibc-2.3.3?
