Hi i am trying to use the katana arm inv_kin plugin and the function getPositionIK.

i get the error terminate called after throwing an instance of 'std::lengtherror' what(): vector::Mfillinsert Aborted (core dumped)

my ikseedstate is: std::vector initsol(5); and my solution is: std::vector solf(5);

i think there is the problem
