{Ubuntu Bug} clearly installed Eigen G2o said to be unable to find

For Eigen

Http://www.linuxdiyf.com/linux/14425.html

Detecting Eigen3 Mounting position

Pkg-config--cflags Eigen3

In this position.

sudo ln-s./eigen3/eigen/./eigen

For G2O

Said G2o/solvers/cholmod couldn't find it, and sure enough it wasn't in the folder.

And then

http://blog.csdn.net/fk1174/article/details/51786031

缺了这句：sudo apt-get install cmake libeigen3-dev libsuitesparse-dev libqt4-dev qt4-qmake libqglviewer-dev

And then it's all right.

It seems that the net should be crossing first, and then read the blog. Sometimes blogs don't write very accurately.
