伙计们，
事情进展如何？ 我终于回到项目中工作了 :D 在我的笔记本电脑上做一些清理工作。 使用 Indigo 安装 14.04。
但是在我的工作区中，在执行catkin_make ，我在gcs_image_bridge.cpp编译中得到了这个：
[ 98%] Built target mavros_plugins

也许与opencv有关？ 我安装了 indigo repo 附带的版本。
有什么建议吗？
希望继续对项目进行一些改进:)
最好的事物，
努诺

顺便提一句，
终端上的pkg-config --libs opencv给了我：

更新：
卸载opencv版本的Indigo，从源码安装opencv： http :
结果一样！ 那么有什么问题呢？

你为什么用ros版本？ 据我所知，它需要系统库。

其中 2.4.8 链接是在 14.10 + Indigo 上构建 mavros 的修复程序。

解决了！ 我有 2.4.8 而不是 2.4.9，安装 2.4.9 解决了。 现在关闭！

嗯，2.4.8 是 14.04 中的一个版本，我做了那个链接来解决构建依赖。

@TSC21我在 Ubuntu 14.04 上遇到了同样的问题，你是如何安装 2.4.9 的 Ubuntu 14.04 只有 2.4.9 ！

问题不在opencv版本中！ 我使用 2.4.9，因为它在 Ubuntu 14.10 中发布。
它在 jenkins 上构建得很好（ indigo trusty
不可以混合 ros opencv 包（放置在/opt/ros ）和系统。
因为ros包提供了实验性的opencv3。
vooon
于 2015-02-18
@vooon你是对的！ 我只是删除了 ros-indigo-opencv3 并正确编译。
为了将来参考，面临同样问题的人也应该这样做：
sudo apt-get remove ros-indigo-opencv3
删除您的构建和开发目录。
非常感谢！
我在之后解决了这个问题：
- $ sudo apt-get install ros-indigo-opencv3
- 删除 /ros_ws/devel 和 /ros_ws/build
- $ catkin_make
