Build_ros script fails

[diegomrt]

Hi,

I'm trying to build the present fully-ROSified version of SD-SLAM but I'm having troubles when executing the build_ros.sh script. Any hints on how I should proceed?

Hi, I think the problem could be that the libSD_SLAM.so hasnt been build previously. In order for the ROS executables to compile they need the lib to be build against it.

The build_ros.sh only builds the ROS executables of SD-SLAM. So first try to build the lib with the build.sh script and only then use the build_ros.sh. Also i would recommend to use clean_build.sh before to remove all previously build files just in case
