Re: [seL4] Can not build RefOS

Hi Xi, Thank for your help. For now, it occurs other error messages as following so I still can not compile RefOS. ~/refos/kernel/src/fastpath/fastpath.c:17:1: *error: conflicting types for ‘fastpath_call’* fastpath_call(word_t cptr, word_t msgInfo) ^ In file included from ~/refos/kernel/src/arch/x86/c_traps.c:15:0: ~/refos/kernel/include/arch/x86/arch/fastpath/fastpath.h:184:6: note: previous declaration of ‘fastpath_call’ was here void fastpath_call(word_t cptr, word_t r_msgInfo) ^ ~/refos/kernel/src/plat/pc99/machine/intel-vtd.c: In function ‘vtd_process_faults’: ~/refos/kernel/src/plat/pc99/machine/intel-vtd.c:236:13: error: format ‘%lx’ expects argument of type ‘long unsigned int’, but argument 2 has type ‘uint32_t’ [-Werror=format=] printf("from bus/dev/fun 0x%lx ", source_id); ^ cc1: all warnings being treated as errors make[1]: *** [kernel_final.s] Error 1 make: *** [kernel_elf] Error 2 Thanks for any help or suggestion, - Gapry 2016-02-11 16:12 GMT+08:00 HyperNewbie :

Hi,

With these pull requests I can compile RefOS.

Hi Xi,

AEP's got renamed to Notification's. So in this example seL4_TCB_BindAEP got renamed to seL4_TCB_BindNotification.

I'm trying to update RefOS. I see seL4_TCB_BindAEP is gone; is there anything similar to replace this? Or do we have to use a separate thread to emulate this behaviour?

RefOS was a student project that is now no longer actively maintained.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.

Dear all,

I follow the official step ( https://github.com/seL4/refos-manifest 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,
