Hello!

I am getting g20 build error on running nice make -j2 install which is as follows:

I have followed Error#76. i am using 'cmake .. -DCMAKE_INSTALL_PREFIX=$G2O_REPO_DIR/install -DG2O_BUILD_EXAMPLES=OFF'.

Error#64: sudo apt-get install libsuitesparse-dev libeigen3-dev:
libsuitesparse-dev is already the newest version (1:4.4.6-1).
libeigen3-dev is already the newest version (3.3~beta1-2).

Result of : sudo apt-get purge ros-kinetic-libg2o libqglviewer-dev:
Package 'libqglviewer-dev' is not installed, so not removed
Package 'ros-kinetic-libg2o' is not installed, so not removed

I have deleted build directory many times and tried with fresh cmake and make but of no use. Kindly help.

I have ubuntu 16.04 and ros-kinetic on my system.

Just resolved the issue. I dont know what was the problem. Removed the libraries installed during installation and started from the scratch. Compilation worked out fine. Will move on to use RGBD SLAM now.
