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,
