Hello,

I am following the instructions for "Creating a workspace" listed in the ROS2 tutorials linked here: https://index.ros.org/doc/ros2/Tutorials/Workspace/Creating-A-Workspace/ . When I run the command: colcon build I obtain the error below:

Starting >>> turtlesim --- stderr: turtlesim
ld: cannot link directly with dylib/framework, your binary is not an allowed client of /usr/lib/libcrypto.dylib for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

make[2]: ** * [libturtlesim_rosidltypesupportfastrtpscpp.dylib] Error 1

make[1]: ** *[CMakeFiles/turtlesim_rosidltypesupportfastrtpscpp.dir/all] Error 2

make: *** ** [all] Error 2

Failed <<< turtlesim [ Exited with code 2 ]

Summary: 0 packages finished [1.67s] 1 package failed: turtlesim 1 package had stderr output: turtlesim

How can I solve this problem so I am able to build these packages that I need?

• running on macOS Catalina 10.15.5
• using Foxy Fitzroy- https://index.ros.org/doc/ros2/Tutorials/Workspace/Creating-A-Workspace/
• Python 3.8.3

Thanks!
