"注意libqglviewer-qt4-dev只在ubuntu 12.04库里有，14.04 里换成另一个库了。g2o的可视化工具g2o_viewer是依赖这个库的，所以，如果你在14.04下面编，要么是去把12.04那个deb（以及它的依赖项）找出来装好，要么用ccmake，把build apps一项给去掉，这样就不编译这个工具了。否则编译过不去。"-- gaoxiang

First I did not ccmake,so I cannot finish :

"这样g2o就装到了你的/usr/local/lib和/usr/local/include下面。你可以到这两个地方去看它的库文件与头文件"

solution:

ccmake install: sudo apt-get install cmake-curses-gui

After installing ccmake , type ccmake .. in terminal.  and  turn off "g2o build apps"
