would you please have a look? There might be some problems with g2o?

Did you install cholmod library? For example,
sudo apt-get install libcholmod2.1.2

[zhm1995]

really thank you for your help
I have figured out this problem

[yaobaishen]

Hi,
I have seen the same error, could you share the solution? I install the libcholmod2.1.2 with no luck.

[yaobaishen]

finally I sove it by: sudo apt-get install libsuitesparse-dev

[zhm1995]

yeah... the same as me...

[yaobaishen]

Sorry，but I see another issue:

slambook/ch10/g2o_custombundle/g2o_bundle.cpp:21:55: fatal error: g2o/solvers/cholmod/linear_solver_cholmod.h: No such file or directory
#include "g2o/solvers/cholmod/linear_solver_cholmod.h"

[zhm1995]

download the suitesparse package in http://faculty.cs.tamu.edu/davis/suitesparse.html

[yaobaishen]

Thanks, after install the suitespase package I should rebuild the g2o library, then the ch10 example could run.

After I tried install dependencies in install_dependencies.sh, I couldn't find cholmod.h either.
However I can find this file in my /usr/include/suitesparse/cholmod.h, so I tried absolute path, It works.
Maybe it's a temporal solution.
