missing separator
I tried to recompile the Examples
@ubuntu:~/catkin_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2/build$ make
[ 0%] Built target rospack_genmsg_libexe
[ 0%] Built target rosbuild_precompile
CMakeFiles/RGBD.dir/build.make:148: *** missing separator. Stop.
CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/RGBD.dir/all' failed
make[1]: *** [CMakeFiles/RGBD.dir/all] Error 2
Makefile:129: recipe for target 'all' failed
make: *** [all] Error
Can you show us the content of
CMakeFiles/RGBD.dir/build.make
around line 148 where it has told you the error is. Plus, it's not a lot of use telling us you've tried a lot of approaches if you don't tell us what they were.
