Question

I am building ROS2 from source on macOS 10.15.1 Catalina. I've followed the instructions here about dependencies, disabled SIP, ignored the ROS1<->2 bridge, and ignoring additional DDS vendors.

I run the following:

mkdir -p ~/ros2foxy/src
cd ~/ros2foxy
wget https://raw.githubusercontent.com/ros2/ros2/531a84a621771a6f4b947d1acad65eb9132f38de/ros2.repos
vcs import src < ros2.repos

and then colcon build --symlink-install. The package qt_gui_cpp fails (see log below).

I am confused by the introduced in macOS 10.15 error, which led me to update from 10.14 Mojave to 10.15 Catalina in the first place. It seems like it may have something to do with how xcodebuild is handling deps?

$ xcodebuild -version
Xcode 11.2.1
Build version 11B500

$ colcon build --symlink-install --packages-select qt_gui_cpp
Starting >>> qt_gui_cpp
--- stderr: qt_gui_cpp

Hey, I think I may have figured it out. The issue seems to be that XCode has turned on the C++17 features but not the C++17 standard library in versions less than macOS 10.15. Therefore to be able to compile in Mojave and older, you will need to add the -mmacosx-version-min=10.15 flag in your CMakeLists.txt file as such:

if(CMAKE_COMPILER_IS_GNUCXX OR CMAKE_CXX_COMPILER_ID MATCHES "Clang")
  add_compile_options(-Wall -Wextra -Wpedantic -mmacosx-version-min=10.15)
endif()

EDIT:

I do have to say that the issue with this method is that you are now targeting 10.15 instead of the version of macOS you are using. What that means is that anything you compile with this method can only be run on macOS 10.15.
