  The imported target "absl::log_severity" references the file

     "/opt/ros/humble/lib/lib/libabsl_log_severity.a"

  but this file does not exist.  Possible reasons include:

  * The file was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and contained

     "/opt/ros/humble/lib/x86_64-linux-gnu/cmake/absl/abslTargets.cmake"

1. Checked the file libabsl_log_severity.a via find /opt/ros/humble -name "libabsl_log_severity.a" and I see it exists

Request: Could you please help resolve this issue

I have never seen this error in all my years in ROS... so I really can't say, seems like not related to thsi project through given how low into cmake it goes. Your best bet is to google around or ask on Robotics Stack Exchange and hope someone's had a similar experience. I'd recommend cleaning your system and rebuilding from scratch after a full update and see if that resolves the issue.

Hope that helps! Sorry this isn't a heres-your-answer response, this seems related to your system setup rather than this package in particular. This package seems to be just what triggers it.

I believe this failure is very easy to reproduce. Here are my steps

1. Install a brand new Ubuntu 22.04
2. Install ros2 iron
3. Install navigation2
4. Install fields2cover using sudo apt install ros-iron-fields2cover
5. Clone this opennav_coverage repo
6. Then build it using colon build, the error of libabsl_log_severity.a missing is there

Hi @SteveMacenski , the error comes from ros-iron-fields2cover installed by apt, could you take a second look? Thanks!

[SteveMacenski]

I'm not the maintainer on fields2cover, you should file a ticket with that project!

Noted, thanks for the quick reply!
