[scarthgap] maximum shebang size exceeded, the maximum size is 128. [shebang-size] on beluga-ros

[mark-bchoi]

Hi,

I have an issue in building beluga-ros package.

error is

ERROR: beluga-ros-2.0.1-1-r0 do_populate_sysroot: QA Issue: : /work/armv8a-oe4t-linux/beluga-ros/2.0.1-1/sysroot-destdir/opt/ros/humble/lib/beluga_ros/occupancy_grid_to_ndt maximum shebang size exceeded, the maximum size is 128. [shebang-size]

NOTE: Tasks Summary: Attempted 3595 tasks of which 3591 didn't need to be rerun and 1 failed.

My build branches are

Yocto branch : scarthgap
ROS2 branch : humble

I think it was caused by shebang size in below files.

Perhaps, it can be related with https://github.com/ros/meta-ros/pull/1215.

If I apply https://github.com/ros/meta-ros/pull/1215, Can I clear this issue?

BR, Mark

I think you can add install append to delete the HOST prefix, refer to do_install:append() in meta-ros2/classes/ros_ament_python.bbclass

Hi @jiaxshi

Thanks for reply. Yes, I added it.

By the way, I think it would not be fundamental solution. there are in many cases added host path to build results in building packages.

WARNING: beluga-ros-2.0.1-1-r0 do_package_qa: QA Issue: File /opt/ros/humble/share/ament_index/resource_index/parent_prefix_path/beluga_ros in package beluga-ros contains reference to TMPDIR [buildpaths]

I hope to find how to fix it fundamentally.

@mark-bchoi It seems that the fundamental problem is that the Python setuptools rewrite the shebang to use whichever Python executable is used to do the install. I encountered this before and this was the solution I used: https://github.com/ros/meta-ros/commit/c2ec1ce7efd5a971c3361ff62923e942f17f494e

@robwoolley Thanks for comment.

I have not drilled this issue yet and it still can not be fixed even I applied patch as https://github.com/ros/meta-ros/commit/c2ec1ce7efd5a971c3361ff62923e942f17f494e and found topic-tools have the same issue.

@robwoolley Sorry I misunderstood for this issue. I can clear this issue with as your solution.

Thanks.

Hi @mark-bchoi, thanks for confirming that it worked. I'm just reopening the issue so I remember to merge in the fix.

Best regards, Rob
