我尝试在ROS答案上向this question提问没有运气，所以我将在这里尝试。
我正在尝试编译ROS Roboearth package，并且与vision_opencv似乎存在一些链接错误。
当我第一次尝试通过提供的说明进行编译时，由于我使用的是旧编译器，而我没有Fuerte，因此无法进行构建。因此，我将Ubuntu升级到12.04，并更新到了ROS Fuerte。
然后，我意识到12.04没有所需的ros-fuerte-vision-opencv2依赖性。因此，我从源代码编译并构建了OpenCV 2.4.3，效果非常好。然后，我意识到我也无法提取再次从here获得的ros-fuerte-vision-opencv， checkout “fuerte”分支并在/ opt / ros / fuerte / stacks / vision_opencv中进行了编译。
现在，当我尝试通过rosmake roboearth
我收到以下链接错误。
谢谢您的帮助。可能只是我缺乏C++知识，但是我尝试了所有工作，从检查依赖项到重新设置编译器标志和依赖项的顺序，我似乎无法使它正常工作。

最佳答案
好的，所以我能够解决问题。
首先，我做了sudo apt-get update，我看到了以下消息:W: Duplicate sources.list entry http://archive.canonical.com/ubuntu/ precise/partner i386 Packages (/var/lib/apt/lists/archive.canonical.com_ubuntu_dists_precise_partner_binary-i386_Packages)
为了解决这个问题，我去了“Synaptic软件包管理器->设置->存储库->其他软件”，并取消选中“规范合作伙伴-由软件中心添加”。
然后又做了sudo apt-get update。这样解决了上述问题。
然后，我转到以下文件/etc/apt/sources.list.d/ros-latest.list，发现该URL已被注释掉。我取消注释以下行deb http://packages.ros.org/ros/ubuntu precise main并再次运行sudo apt-get update。
之后，我能够通过apt-get安装roboearth所需的所有依赖项，并能够使用rosmake roboearth成功制作roboearth
