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

fatal: Couldn't find remote ref refs/heads/new-rt

error: Cannot fetch seL4.git from https://github.com/seL4/seL4.git

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.

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:
