When trying to cross-compile using the instructions at: https://github.com/ros2/ros2/tree/master/arm_crosscompilation

It fails with the following:

Hi, I met the same issue today with cross-compile on arm platform.
@amar-laksh , I tried https://github.com/amar-laksh/resource_retriever/commit/edbcb73e89743ac8b5ca2c3a4fd326b2d2fcd9de But it did not work.

Could you please tell me if there is any additional patch I should apply? Or is there any way to skip the ROS building?

[amar-laksh]

@davidhuziji , Hey! this might help you: #17 It's not upstreamed yet.

[davidhuziji]

Hi, @amar-laksh, Thanks a lot.
May I know the difference between #16 and #17? They look like the same.

[davidhuziji]

Hi @amar-laksh , I made some comments on your patch. Could you please help take a look?

Now this exact issue comes up when compiling rviz_rendering in eloquent elusor release of Ros2, tried the fix suggested here, unfortunately to no avail.

It seems it could be because of assimp 5.0 I'm not sure though, uninstalling it from brew, solves it though (not sure it's my preferred solution though)
