Actually, my previous comment doesn't make anysense. Please ignore it. Actually it looks like you'd need to do `brew install pcre`. If that command resolves your issue we'll put that in the instructions. You should not, however, need to have `poco` installed from Homebrew for the binary to work. Sorry for the confusion. --- [Visit Topic](https://discourse.ros.org/t/talker-example-on-macos-failed-ros2/1649/5) or reply to this email to respond.
