RefOS was a student project that is now no longer actively maintained. It would make an ideal community or personal project for somebody to pick up, albeit one with a steep initial learning curve.

Yes, you are hitting API changes. The best way forward would be to port RefOS to the newer API. Downgrading would be a temporary solution at best.

Subject: [seL4] Can not build RefOS

Dear all,

I follow the official step (https://github.com/seL4/refos-manifest) to build RefOS and it occurs the following error message.

In file included from /home/chi-wai/Workspaces/microkernel/RefOS/libs/librefos/src/sync.c:16:0:

make[1]: *** [src/sync.o] Error 1

make: *** [librefos] Error 2

Does RefOS use the old seL4 API ? If it is, which version I need to downgrade?

Thanks for any help or suggestion,

Gapry.
