江湖救急啊！

昨天看到wayland-1.0放出来了，一时心血来潮，想试试wayland，
于是一口气加了gnome、x11等overlay。
然后emerge了一堆包：
wayland-9999、mesa-9999、libxcbcommon-9999等。
wayland没看啥动静（不想装演示用的weston，又不知道怎么用wayland),
今天早上发现git不能用了，甚至layman -S、revdep-rebuild等都不能用了。
原来少了libpcre.so.0，也即

# cd /usr/bin/
# ldd git
linux-gate.so.1 => (0xb7839000)
libpcre.so.0 => not found
libz.so.1 => /lib/libz.so.1 (0xb7804000)
libpthread.so.0 => /lib/libpthread.so.0 (0xb77ea000)
libc.so.6 => /lib/libc.so.6 (0xb7686000)
/lib/ld-linux.so.2 (0xb783a000)

复制代码

尝试emerge -av1 libpcre也以失败告终。

现期盼大侠传一份libpre.so.0来救急，最好告知安装路径！
谢谢。

emerge dev-libs/libpcre 不就可以了吗。

不是 libpre 是 libpcre.

其实，我前面已经提到过了，给出结果:

这里只提到了 grep 错误，试试 USE="-pcre" emerge grep 然后再安装 libpcre 试试看？

还是无法emerge，为了看到libpcre.so.0库的重要性，请看

哎，看来overlay还是比较危险的，莫名其妙地就把libpcre.so.0给删去了。

其实跟overlay没啥关系，看一下libpcre这个包的changelog：
http://sources.gentoo.org/cgi-bi ... angeLog?view=markup

在2月5日接连发了三个ebuild，尤其是最后一个，libpcre-8.30-r2，写的是“Revbump to add preserve old lib support and remove old.”。大概就是出了问题打上补丁的。

由于早上停电，我emerge --sync的时候，libpcre已经是8.30-r2了，emerge完之后有提示运行"revdep-rebuild --library '/lib64/libpcre.so.0'"来修复，重新emerge了几个包。不清楚较早的另外两个版本有没有提示你运行revdep-rebuild。。。

1. 楼上也说了，跟overlay没关系。请先sync
2. 我说的是个临时方法。pcre虽然重要，但是不是可以通过 -pcre 的方法暂时绕开它，然后寻找相关方法修复。

祝你好运：）

现在libpcre的版本

# eix libpcre

Homepage: http://www.pcre.org/
Description: Perl-compatible regular expression library

复制代码

查看elogview，根本没有相关提示。
再尝试执行

# revdep-rebuild --library '/lib/libpcre.so.0'

复制代码

有如下错误：

grep: error while loading shared libraries: libpcre.so.0: cannot open shared object file: No such file or directory

在查看lib目录，可看到

# ls /lib/libpcre*
libpcre.so.1 libpcre.so.1.0.0

复制代码

汝之奈何？

好吧，无论emerge --sync还是 USE="-pcre" emerge -avutDN world，均不成功。
值得临时的使用 ln -s libpcre.so.1 libpcre.so.0，
暂时解决问题。

但总觉的很dirty!

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'。
