Unable to build rosbag2_storage

[FullMetalNicky]

Description

I have ROS2 Foxy build from source, and everything works fine there.
I created a new workspace for rosbag2, as suggested in the readme.
I cloned foxy-future and tried to build the package with colcon build --merge-instal
I did the same with the master branch too

Expected Behavior

I expected the packaged to be built, so I can use the python-API for rosbag2

Actual Behavior

The build failed on rosbag2_storage (see additional context)

To Reproduce

** Steps to reproduce the behavior, e.g.

1. git clone rosbag2 from foxy-future or master
2. colcon build --merge-install

System (please complete the following information)

• OS: Ubuntu 20.4
• ROS 2 Distro: Foxy

master is the Rolling / Galactic source branch - it is not expected to build against a Foxy installation. Additionally - foxy-future is not yet implemented, if you would like to try building it now, please check out the branch from the PR #687

So - this behavior is currently as expected - I will close this ticket.

Hello all,
after git checkout foxy-future, build OK. So, how to use let ros2 bag play [ros2_bag] play the /clock topic.
My OS is ubuntu20.04, installed foxy by debian. I want to play ros2 bag offline to test a slam and localization system. /clock topic is not published by anyone.
