Hi

It seems I faced with similar error.

How have you solved your error?

With regards,

Have you install install Boost by typing:

$ sudo apt-get install libboost-dev
if you already did
try this:
delete all folders in your workspace except "src"
and then catkin_make again

hope it helps you

Hi Jacky

Thank you for your suggestions.

I have installed the Boost already early.
Also I have tried to delete all folders and run catkin_make, however I have got the error anyway.

Maybe there is another solution?

Best Regards,
Alex

Hi Alex, did you try with the nm command to understand the error? Also it is look like you have issues with g2o because the symbol ZN3g2o17csparse_extension14cscholsolsymbEPK12cs_di_sparsePdPK14cs_di_symbolicS4_Pi
looks like it make reference to csparse solver and cholesky factorization that are from g2o.
You can try standalone version of S-PTAM with the KITTI dataset to discart ROS issues.

Let me know if it helps.
