Rosen/all:
I create a bunch of extra environments for IK, but I can't use more than one without getting a seg fault. Partial code below. Any advice?
Thanks.

---------------------------
std::vector<OpenRAVE::EnvironmentBasePtr> raveEnvCopies;
for(size_t i = 0; i < numThreads; i++)
{
raveEnvCopies[i] = env->CloneSelf(OpenRAVE::Clone_Bodies);
}
...
vector<...> poses; //want to run IK for all of these
const size_t numThreads = 1;//raveEnvCopies.size(); //works fine with 1 thread; TODO haven't gotten it to not seg fault when using multiple threads here -- ??
for(size_t m = 0; m < numThreads; m++)
createThread([m]()
{
OpenRAVE::RobotBasePtr robot = raveEnvCopies[m]->GetRobot(robotCamHandler->getRobotName());
OpenRAVE::RobotBase::ManipulatorPtr manip = robot->GetActiveManipulator();
for(size_t i = m; i < poses.size(); i += numThreads)
{
const OpenRAVE::IkParameterization ikTgtXform(poses[i], OpenRAVE::IKP_Transform6D);
vector<OpenRAVE::dReal> soln;
{
// OpenRAVE::EnvironmentMutex::scoped_lock lock(raveEnvCopies[m]->GetMutex()); // lock environment; I think unnecessary if we use envs we don't also use for anything else
manip->FindIKSolution(ikTgtXform, soln, 0);
}
}
});
