I couldn't find any convenience methods to convert rospy.Time to datetime.datetime. Timezones and other issues make this less trivial than it appears, especially for novice users.

Am I missing something obvious, or is this a textbook case of "nope, not done yet, please submit a patch?"

Thanks!

I'm trying to get dependency tracking in our package.xml files squared away, but ROS seems to be trying to treat libeigen3-dev as a ROS package rather than a system dependency.

Specifically, I've got a package that depends on Eigen, the well-known header-only linear algebra library. Sounds like a build dependency, so:

<build_depend>libeigen3-dev</build_depend>
<export_build_depend>libeigen3-dev</export_build_depend>

Here's what happens when I run rosdep check:

    ~/sentry_dev_ws$ rosdep check --from-paths src --ignore-src
All system dependencies have been satisified
ERROR[ds_sim]: Cannot locate rosdep definition for [libeigen3-dev]
    rosdep key : libeigen3-dev
    OS name    : ubuntu
    OS version : xenial
    Data: no data

Changing the dependency name to "eigen" fixes this, but eigen isn't an ubuntu apt package name. I have the same issue with google protobuf, and will probably have it again in the future.

I have a suspician catkin's packaging tools will prove very poweful. Just gotta figure them out first.

Thanks!

Is there a clever way to recover all system dependencies for the set of packages in a workspace? Something like rosdep resolve, but that works on ROS packages in a catkin workspace?

Ok, I found an answer. You have to create a temporary logger config file that sets the requested log debug level. Here
