Sorry, I don't mean sync with that manifest, but try directly fetching the revisions in each repository in your current checkout.
Thanks
Anna.

Hi Anna,
Thanks for your reply.
I have tried to sync with the mcsmanifest.xml but it reported the following errors.
Fetching project seL4.git
fatal: Couldn't find remote ref refs/heads/new-rt

Hi Zeyu,
The MCS tutorials are not currently up to date with the latest libraries.
I've attached a manifest which was the last version that worked - can you tell me if the revisions in it work for you? If so I can tag them all and update the tutorials.
Cheers
Anna.

Subject: [seL4] Compilation Errors for the MCS tutorial
Hi,
I was trying the MCS tutorial but encountered a few compilation errors which I cannot resolve. And the previous tutorials can be compiled normally.
The building environment is based on Docker, as recommended by the tutorials.
Steps:
1. cd kernel
2. git fetch seL4 mcs-tutorials
3. git checkout mcs-tutorials
4. cd .. && ./init --tut mcs
5. cd mcs && ninja
Compilation output about the errors:
