[ompl-users] OMPL Build Error [Ubuntu Linux]

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Dear Alex,

If you take a look at one of the latest commits of OMPL:
https://bitbucket.org/ompl/ompl/commits/4a0a100c9435a0b5b66db17b193d3fcbfc5b2552

You will see that OptimizationObjective has been modified: the getCost
method has been removed from OptimizationObjetctive and this logic has been
transferred to Path classes.

Therefore, yes, the error is because that old source you neglected to
remove :)
