Not launching on Pi

[jpace121]

Getting error:

j7s-sub-1] terminate called after throwing an instance of 'rclcpp::exceptions::RCLInvalidArgument'
[j7s-sub-1]   what():  failed to create interrupt guard condition: context argument is null, at /home/jimmy/ros2_ws/src/rcl/rcl/src/rcl/guard_condition.c:65

May need to recompile foxy?

I tried recompiling, but ran into some rosdep issues I don't feel like going down a rabbit hole to solve....

I think the easiest path forward will be to switch from Debian armv7l to Ubuntu armhf.

Got past the rosdep stuff.
rcutils added a dependency on mimick which doesn't build on armv7l, so this isn't going to work now.

See github.com/ros2/Mimick/pull/ 14

Same error after recompiling ros2 when running the example subscriber.

I think something is up with rclutils.

Things work when run from my Debian armv7l docker with qemu, so this looks like it must be something wierd that's specific to Raspbian or the rpi hardware?

[jpace121]

I'm thinking I'm going to need to jump to the 64-bit arm builds...

EDIT: Upon further reflection I wasn't testing with the latest build that had DebInfo on the last test. Now I'm getting different errors atleast.

EDIT: Seg fault city... Going to try going to arm64.

Switched to arm64.
