Description
TrackFinder Track3DKalmanSPS_module.cc defines uniqueSpptIt, but does not use the variable. This is picked up as a warning and treated as an error by gcc 6.4. Since it appears that the definition has side effects, this code should be reviewed and fixed by the experts.
art::PtrVector<recob::SpacePoint>::iterator uniqueSpptIt =
std::set_union(spacepointssExcise.begin(),spacepointssExcise.end(),
spacepointssExcise.begin(),spacepointssExcise.end(),
As a workaround, "cet_add_compiler_flags(CXX -Wno-unused-but-set-variable)" has been added to TrackFinder/CMakeLists.txt

I have verified that the result of the incriminated line can be discarded with no side effects.
#3 Updated by Gianluca Petrillo almost 3 years ago
Ops, I should clarify: the new code should look like:
std::set_union(spacepointssExcise.begin(),spacepointssExcise.end(),
spacepointssExcise.begin(),spacepointssExcise.end(),
spacepointssExcise.begin()
);so only the part on the first line,
art::PtrVector<recob::SpacePoint>::iterator uniqueSpptIt =, is superfluous.#4 Updated by Gianluca Petrillo almost 3 years ago
The fix was pushed into develop branch of larreco.
