Ubuntu循环依赖(Cycle Dependency)的解决[免编译+解决步骤]
最近在VMware中安装了一个Ubuntu系统。由于创建系统时没有要求安装虚拟网卡，因此需要安装Ubuntu的软件包时，需要自己下载deb 文件，拖进系统，然后双击调用gdebi进行安装。可是，当我尝试安装G++时却出现了问题：g++-4.1这个包依赖libstdc++6-4.1- dev这个包（也就是C++库），而libstdc++6-4.1-dev又依赖g++-4.1。结果两个包都装不上。
最近在VMware中安装了一个Ubuntu系统。由于创建系统时没有要求安装虚拟网卡，因此需要安装Ubuntu的软件包时，需要自己下载deb 文件，拖进系统，然后双击调用gdebi进行安装。可是，当我尝试安装G++时却出现了问题：g++-4.1这个包依赖libstdc++6-4.1- dev这个包（也就是C++库），而libstdc++6-4.1-dev又依赖g++-4.1。结果两个包都装不上。
上网搜索，在Ubuntu官方论坛找到了解决方法：
在命令行下执行以下语句
sudo dpkg -i &ignore-depends=libstdc++6-4.1-dev g++-4.1_4.1.2-0ubuntu4_i386.deb
sudo dpkg -i &ignore-depends=g++-4.1 libstdc++6-4.1-dev_4.1.2-0ubuntu4_i386.deb
（g++-4.1默认安装包名为g++-4.1_4.1.2-0ubuntu4_i386.deb；libstdc++6-4.1-dev默认安装包名为libstdc++6-4.1-dev_4.1.2-0ubuntu4_i386.deb）
也就是说，强行让两个安装包忽略依赖项。
使用apt-get自动安装应该没有这种问题。
附：dpkg命令中文帮助信息
用法：dpkg [&选项& ...] &命令&
-i|&install &.deb 文件名& & | -R|&recursive &目录& &
&unpack &.deb 文件名& & | -R|&recursive &目录& &
-A|&record-avail &.deb 文件名& & | -R|&recursive &目录& &
&configure &软件包名& & | -a|&pending
&triggers-only &软件包名& & | -a|&pending
-r|&remove &软件包名& & | -a|&pending
-P|&purge &软件包名& & | -a|&pending
&get-selections [&表达式& ...] 把已选中的软件包列表打印到标准输出。
&set-selections 从标准输入里读出要选择的软件。
&clear-selections 取消选中所有不必要的软件包。
&update-avail &软件包文件& 替换现有可安装的软件包信息。
&merge-avail &软件包文件& 把文件中的信息合并到系统中。
&clear-avail 清除现有的软件包信息。
&forget-old-unavail 忘却已被卸载的不可安装的软件包。
-s|&status &软件包名& & 显示软件包详尽的状态信息。
-p|&print-avail &软件包名& & 显示可供安装的版本详情。
-L|&listfiles &软件包名& & 列出所有&属于&该软件包(或多个)的文件。
-l|&list [&表达式& ... 简明地列出软件包的状态。
-S|--search &表达式& ... 搜寻拥有该文件(或多个文件)的包。
-C|--audit 检查搜寻残损的软件包。
--print-architecture 显示 dpkg 体系架构。
--compare-vesions &关系& 比较版本号 - 见下。
--force-help 显示本强制选项的帮助信息。
-Dh|--debug=help 显示有关出错调试的帮助信息。
-h|--help 显示本帮助信息。
--version 显示版本信息。
--license | --licence 显示版权和许可证条文。
对归档文件使用 dpkg -b|--build|-c|--contents|-e|--control|-I|--info|-f|--field|
-x|--extract|-X|--vextract|--fsys-tarfile (输入 dpkg-deb --help)。
供内部使用：dpkg --assert-support-predepends | --predep-package |
--assert-working-epoch | --assert-long-filenames | --assert-multi-conrep。
--admindir=&目录& 使用 &目录& 而非 /var/lib/dpkg。
--root=&目录& 安装到另一个根文件系统。
--instdir=&目录& 改变安装的根目录的同时保持管理(admin)目录不变。
-O|--selected-only 忽略没有被选中安装或升级的软件包。
-E|--skip-same-version 忽略版本与已安装软件版本相同的软件包。
-G|--refuse-downgrade 忽略版本早于已安装软件版本的的软件包。
-B|--auto-deconfigure 就算会影响其他软件包，也要安装。
--[no-]triggers 跳过或强制随之发生的触发器处理。
&no-debsig 不去试图验证软件包的签名。
&no-act|&dry-run|&simulate
仅仅报告我们要执行的操作 - 但是不执行。
-D|&debug=&八进制数字& 开启调试功能(参见 -Dhelp 或者 &debug=help)。
&status-fd 发送状态改变的更新信号到文件描述符。
&log=&文件名& 把状态的更动和操作信息记录到 &文件名&。
&ignore-depends=&软件包名&,&
忽略关于 &软件包名& 的所有依赖关系。
&force-& 忽视遇到的问题(参见 &force-help)。
&no-force-&|&refuse-&
当遇到问题时中止运行。
&abort-after 遇到个错误后终止。
可供&compare-version 使用的比较运算符有：
lt le eq ne ge gt (如果版本号为空，那么就认为它先于任意版本号)；
lt-nl le-nl ge-nl gt-nl (如果版本号为空，那么就认为它后于任意版本号)；
& && &= = &= && & (仅仅是为了与主控文件的语法兼容)。
