RGBDSLAM error: Trust certificate g2o problem

edit

Hey guys,

I am using ubuntu 12.04 and ros fuerte. I am trying to run rgbdslam.

I followed the instructions given in this post http://answers.ros.org/question/50585/rgbdslam-error-in-fuerte-and-electric/ (link text): and I got the following error:

svn --non-interactive --config-dir /home/samme/trunk/g2o/svnconf co https://svn.openslam.org/data/svn/g2o/trunk build/g2o svn: OPTIONS of 'https://svn.openslam.org/data/svn/g2o/trunk': Server certificate verification failed: issuer is not trusted (https://svn.openslam.org)

Note: I had previously downloaded g2o from the svn: https://openslam.informatik.uni-freiburg.de/data/svn/g2o/trunk/. I then moved the file trunk to the rubbish bin and downloaded g2o again from the svn : https://code.ros.org/svn/ros-pkg/stacks/vslam/trunk/

I have been told to add the line: SVN_CMDLINE = svn--trust-server-cert--non-interactive --config-dir $(TOP_DIR)/svnconf to the makefile in the g2o folder.

However I am now getting this error:

svn--trust-server-cert--non-interactive --config-dir /home/samme/trunk/g2o/svnconf co https://svn.openslam.org/data/svn/g2o/trunk build/g2o make: svn--trust-server-cert--non-interactive: Command not found

Am I doing the command correctly? I really appreciate your help.

Regards,

Khalid
