I entered the container from the runner machine while the ci was running and I noticed that the repository was cloned as root but the build directories were created under a user. The cofigure_file command is trying to modify a file from the repository, so it's like user is trying to modify a file created as root (when cloned). I didn't manage to make the gitlab-runner software clone the repository as user. Instead, my workaround was to change the permissions of the folder before building. My .gitlab-ci.yml looks like this now

QUESTION

CMake No rule to make target

Asked 2021-Jun-07 at 01:45

I'm trying to build ORB_SLAM2 on macOS 11.4 with clang 12 and OpenCV4 and have run into this error:

make[2]: *** No rule to make target `/usr/lib/libz.dylib', needed by `../lib/libORB_SLAM2.dylib'. Stop.

This file does not exist on my Mac and I cannot add this symlink due to macOS's SIP. The correct path should be /usr/local/opt/zlib/lib/libz.dylib

How can I fix this /usr/lib/libz.dylib reference?

Here is my branch with my macOS build changes.

I've tried to fix the problem by:

Inspecting each of the project's direct dependencies with otool -L and rebuilt from source where necessary (such as OpenCV) to make sure /usr/lib/libz.dylib is not referenced (fix suggested here)
Using CMake's FindZLIB.cmake module in the ORB_SLAM2 CMakeLists.txt to ensure the correct ZLIB is found

Below is the output showing ZLIB is found but still no luck:

Solved: I checked the CMakeFiles/Makefile.cmake and it showed me that the Pangolin library I was using was actually one from another project of mine. Building Pangolin in this project solved the issue.

This is an annoying compatibility error. The ORB SLAM you are trying to use only works with Ubuntu 18.04. But, on the ROS ORB SLAM page, they have a new one called orb_slam_ros (click here) that does the same thing.

NOTE: The new one doesn't say that it outputs ROS maps but using Octomap, you can convert a PointCloud to a Map. NOTE: This is tested in Ubuntu 20.04 ROS Noetic. As of now, 20.10 doesn't work.

Maybe your camera isn't getting picked up. You are using cv_camera_node meaning that the default topic will be cv_camera but orb_slam2 requires just camera. To solve this, go into the cv_camera_node.cpp which will look like this:
