按我的临时方法在emerge --sync之后，发现libpcre的版本已经成了dev-libs/libpcre-8.30-r2，真快啊，而且elogview确实也出现了revdep-rebuild --library '/lib/libpcre.so.0'。

顺便提一句，我运行“revdep-rebuild --library '/lib/libpcre.so.0'“之后，编译php过不去。不过不是什么大问题，大概明天更新的时候就会修复了。

• 还是Portage-2.2-alpha*好啊，preserve-libs功能保证不会出现这种问题。
  
• 另外，make.conf FEATURES变量中的buildsyspkg很值得打开，可以自动保留所有旧系统包的二进制包。不过libpcre恰巧不在@system中... 也可以考虑开buildpkg，但需要周期性eclean-pkg -d -t3d 。

速度没有这么快啦。gentoo的bug站都没看到相关信息，还是arch的反应快。

呵呵，就是那么快。今天sync之后libpcre就降为8.21了，看ebuild，是php的DEPEND里加上<libpcre-8.30这一行。。。

我的妈妈啊！
昨天用ln 给libpcre建了个软连接，今天尝到恶果了。
执行完revdep-rebuild --library '/lib/libpcre.so.0'之后，发现

这下不敢妄动系统的文件了。

请高手指点！

很理所当然呀，libpcre降级到8.21，那libpcre.so.1就被干掉了，于是就会有一堆依赖它的包不正常。先手动做一个链接：

1. ln -s libpcre.so.0 libpcre.so.1

复制代码

然后emerge -uvaDN world，emerge -ac，revdep-rebuild三板斧，都弄好之后再运行：

1. revdep-rebuild --library '[color=red]/lib/libpcre.so.1[/color]'

复制代码

把依赖libpcre.so.1的那些包都转为依赖libpcre.so.0，最后删掉libpcre.so.1这个链接就好了。

我的妈妈啊！
昨天用ln 给libpcre建了个软连接，今天尝到恶果了。
执行完revdep-rebuild --library '/lib/libpcre.so.0'之后，发现

• 您太草率了，不稳定分枝中有很多这种情况。核心包的升级/降级最好要等ebuild出现两三天之后再做。
• 第一步的解救方法，请按timemars指出的做软链接。
• 第二步我的建议是立刻升Portage-2.2（目前是2.2.0_alpha85，需要在/etc/portage/package.keywords中做个手脚），不要revdep-rebuild。portage-2.2有preserve-libs功能，默认开启，可以保留仍然被使用的旧版本库文件，而在一段时间内不做revdep-rebuild。尽管名义上是alpha版但相当稳定。
  
  接下来用quickpkg备份libpcre-8.21，以防万一：
  
  1. quickpkg libpcre

  复制代码
  
  
  接着无视依赖强制升级libpcre： （-O 就是--nodeps，无视依赖安装任何包）
  
  1. emerge -O1 '=dev-libs/libpcre-8.30-r2'

  复制代码
  
  
  然后就高枕无忧了... 下一次emerge -uD @world时，portage会将libpcre再次降级到8.21，照做就好。Portage-2.2的preserve-libs应该会自动保留'=dev-libs/libpcre-8.30-r2'提供的libpcre.so.1.0.0，因此不会导致日后编译出错。revdep-rebuild或者emerge @preserved-rebuild都不需要，因为php等少数几个依赖=dev-libs/libpcre-8.21的包很快就会支持=dev-libs/libpcre-8.30-r2，这样现在省去了很多时间，日后再次升级到8.30时重新编译100多个包的麻烦也消除了。
• 再次建议在/etc/make.conf FEATURES变量中打开buildsyspkg/buildpkg，具体原因请参见我的上一个回复。（另外为什么我发现您倾向于无视我的回复...）
