ValueError when creating plugin under Ubuntu 14.04 and ROS Indigo #49

Closed pirobot closed 9 years ago

pirobot commented 9 years ago

My setup is Ubuntu 14.04 and ROS Indigo Debian install. I am using version 0.9 of OpenRave, source install since Debian packages for Ubuntu 14.04 are not yet available.

After building the .cpp file using OpenRave's ipfast.py utility, I get the following error when trying to build the plugin:

$ rosrun moveit_ikfast create_ikfast_moveit_plugin.py pi_robot right_arm pi_robot_ikfast_right_arm_plugin `pwd`/output_ikfast61.cpp
Warning: The default search has changed from OPTIMIZE_FREE_JOINT to now OPTIMIZE_MAX_JOINT!

My output_ikfast.cpp file can be found here.

I'm pretty sure this has already been fixed when we merged #48. It just hasn't been released yet.

You don't mention it, but did you install a released version of moveit_ikfast (debs)? If so, please try a from-source build and see whether that allows you to continue.

pirobot commented 9 years ago

Thanks @gavanderhoorn -- building from source works. And yes, I should have mentioned I was using the Indigo deb version.

mikeferguson commented 9 years ago

Should we push a new indigo release then?

gavanderhoorn commented 9 years ago

I guess we could. Would include #48 and some other minor updates.

Hi @pirobot, can you provide me the detailed steps on installing ikfast and openrave on ubuntu14.04 with ROS indigo? Thanks in advanced for your reply!

gavanderhoorn commented 9 years ago

@chamberger: I hate to sound like a broken record, but could you please ask this question on ROS Answers? Not only would that help others, it would also not hijack this issue with something that is at best tangential.

Thanks.
