libstdc++ conflicts itself， perl， yast， git

Issue： 在 openSuSE 11,12,13的某些版本中，通过yast安装 git 工具包，会遇到类似问题：

Problem: solvable libstdc++6-4.8.1_20130909-3.2.1.i586 conflicts with libstdc++6 provided by itself

Why do some packages conflict with themselves?
“Oneiric supports Multi-Arch,that is,allowing you to install packages of different architectures simultaneously (currently i386 and amd64 a.k.a. 32-bit and 64-bit).?Some packages cannot be installed simultaneously (like libc6:i386 and libc6:amd64).?aptitude?cannot handle these cases?and therefore thinks that it may be a good idea to remove those packages. It’s recommended to use?apt-get?now.”

解决办法：

Package conflicting with itself？

Can't?you?just?force-install?libstdc++6-4.8.1_20130909-3.2.1.i586?

强制重新安装

libstdc++6-4.8.1_20130909-3.2.1.i586

shell> wget “ftp://bo.mirror.garr.it/pub/1/opensuse/distribution/13.1/repo/oss/suse/i586/libstdc++6-4.8.1_20130909-3.2.1.i586.rpm”
shell>?rpm -ivh –nodeps –force libstdc++6-4.8.1_20130909-3.2.1.i586.rpm
然后再安装 perl相关的一些工具包
shell>?zypper -v install –force-resolution yast2-perl-bindings

之后可能会碰到一些其他异常或者丢失，缺啥少啥补啥。

这一过程中，还可能遇到 yast 无法使用，或者
shell> perl -MCPAN -eshell
无法调用的情况，均是由于在安装过程中 libstdc++ 的版本问题遇到故障，可以在解决上来上面的问题之后，重新安装 perl 即可。

本质上，每个软件的版本都有与之同期的对应的版本相配合，跨时期的软件版本很难融合。这是本次，也是上次?apache 和 resin融合遇到的问题的共同特征。
