Do you know if it is still in the roadmap or if it has been implemented?

No. It is not possible, sorry. I made the same question here: https://github.com/ros2/rosidl_typesupport/issues/128

No. It is not possible, sorry.

@fastestindian, Did you resolve it?

Dear ROS users,

I am not able to set an array of string as a launch argument in a launcher:

def generate_launch_description():
    vals = ['A', 'B']
    model_files = LaunchConfiguration('model_files', default=vals)

    declare_model_file_cmd = DeclareLaunchArgument(
      'model_files',
       default_value=vals,
       description='PDDL Model file')

    # Specify the actions
    domain_expert_cmd = Node(
      package='plansys2_domain_expert',
      node_executable='domain_expert_node',
      node_name='domain_expert',
      output='screen',
      parameters=[{'model_files': model_files}])

    ld = LaunchDescription()
    ld.add_action(declare_model_file_cmd)
    ld.add_action(domain_expert_cmd)

    return ld

In my C++ node:

    declare_parameter("model_files", std::vector<std::string>());

I receive this message:

[domain_expert_node-1] terminate called after throwing an instance of 'rclcpp::ParameterTypeException'
[domain_expert_node-1]   what():  expected [string_array] got [string]

Does anybody know how to use an array of string as a launcher argument?

Best

How did you resolve this? I have the same problem...

It is an updated xenial distro, and gtest is installed using the libgtest-dev package in the distro (1.7.0-4). Obviously

For some time now (due to some update, probably), I have problems with GTest when compiling a workspace.

When installing GTest on the system, libgtest.so and libgtest_main.so are created, and cmake finds them. They are static or dynamic depending on how it is installed. Everithing is OK (I suppose)

When compiling a workspace, I always have the same error:

This is caused because in /opt/ros/kinetic/share/catkin/cmake/test/gtest.cmake:363, libgtest.so is required to be built, even if it exists in the system, producing that error.

Is there something I'm doing wrong, or is it misconfigured in my system?

Yes, it fixed my problem :) Thanks!!! The point is that, as far as I know, 0.7.11 is the current version for kinetic xe
