Dear all,

I recently faced with the following error whenever I run rosmake * to build a set of packages using rosbuild

Exception in thread 6:
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner
    self.run()
  File "/opt/ros/melodic/lib/python2.7/dist-packages/rosmake/parallel_build.py", line 161, in run
    (result, result_string) = self.rosmakeall.build(pkg, self.argument, self.build_queue.robust_build)
  File "/opt/ros/melodic/lib/python2.7/dist-packages/rosmake/engine.py", line 436, in build
    warning_dict = warnings.analyze()
  File "/opt/ros/melodic/lib/python2.7/dist-packages/rosmake/gcc_output_parse.py", line 41, in analyze
    return {(t, self.byType(t)) for t, p in self._warning_pattern_map.items()}
  File "/opt/ros/melodic/lib/python2.7/dist-packages/rosmake/gcc_output_parse.py", line 41, in <setcomp>
    return {(t, self.byType(t)) for t, p in self._warning_pattern_map.items()}
TypeError: unhashable type: 'list'

I am using ROS melodic in Ubuntu 18.04 :

ROS_ETC_DIR=/opt/ros/melodic/etc/ros
ROS_ROOT=/opt/ros/melodic/share/ros
ROS_MASTER_URI=http://localhost
ROS_VERSION=1
ROS_PYTHON_VERSION=2
ROSLISP_PACKAGE_DIRECTORIES=/home/hamidreza/universal_robot_ws/devel/share/common-lisp:/home/hamidreza/catkin_ws/devel/share/common-lisp
ROS_DISTRO=melodic

It should be noted that I can make the packages if I do roscd to the package and then "make" it.
I even installed fresh ubuntu but it was not helpful. Does anyone encounter this issue before?

* [update] I confirmed that it happened after updating the ubuntu by sudo apt-get update && sudo apt-get dist-upgrade

Thanks,

Hamidreza

As a quick sanity check... why are you using rosmake with melodic and Ubuntu 18.04? Rosmake was deprecated a long time ago in favor of catkin. Rather than debugging some strange issue with a long-deprecated tool, just want to understand why you are even attempting rosmake.

@jarvisschultz, we have a very big cognitive robotic system, most of the packages have been developed based on the catkin building system, while there are still several rosbuild-based tool packages.

Sounds good. Just wanted to make sure you really needed to debug the rosmake problem

jarvisschultz ( 2020-08-24 18:07:55 -0500 )edit

Glad you were able to fix it! The ros/ros GitHub repo would be the proper place to submit a bug report, or preferably, a PR to fix the issue.

BTW, I updated your comment to be an answer so that this question now shows up as answered. If you do submit a bug or a PR, it would be good to add a comment here linking that issue/PR

@jarvisschultz Where is the evidence that rosmake was deprecated? In its official ROS Wiki, the status is maintained, and no mention about the deprecation. Of course I know catkin_make is much more popular, though.

@akihiko Maybe deprecation is too strong of a word, but referring to catkin as merely "popular" seems too weak. I suppose you are correct that rosmake could still potentially work because under-the-hood it uses rospack which works with both rosbuild and catkin packages. It would have been more correct for me to say rosbuild is deprecated. I tend to think of rosmake as a rosbuild-specific tool, but thinking about it more that is not quite right. All that said, I'm still of the opinion that you would want a compelling reason to use rosmake over catkin_make in a ROS1 distribution newer than Indigo.

jarvisschultz ( 2021-10-21 09:58:11 -0500 )edit

rosmake cannot build Catkin packages.

That immediately makes it unusable on any recent ROS distribution.

It's certainly deprecated -- perhaps if only already de facto.

@jarvisschultz, we found and solved the problem, The analyze() function in /opt/ros/melodic/lib/python2.7/dist-packages/rosmake/gcc_output_parse.py file causes the problem. It uses the { } in the return expression to unhash tuples, but the tuples should contain only strings, numbers, or tuples. In some cases, the tuples contain empty lists that are unhashable and therefore cause the problem.

    def analyze(self):
    """Get dictionary of classified warnings.

    @return A dictionary of lists of warning messages indexed by the warning type
    @rtype {str:[str]}
    """
    return {(t, self.byType(t)) for t, p in self._warning_pattern_map.items()}

We fixed it by updating the last line as:

  return dict((t, self.byType(t)) for t, p in self._warning_pattern_map.items())

all packages compiled without problems. should we mention this point somewhere to be corrected in the next update of melodic?

Thanks, Hamidreza
