I'm interested in CEPH too. Can you tell us what is your plan with fio & CEPH ? ----- Mail original ----- De: "Daniel Gollub" <daniel.gollub@xxxxxxxxxxx> À: "Jens Axboe" <axboe@xxxxxxxxx> Cc: fio@xxxxxxxxxxxxxxx, "Daniel Gollub" <d.gollub@xxxxxxxxxx> Envoyé: Jeudi 13 Février 2014 07:13:57 Objet: Re: [PATCH] Fix g++ warning about void* used in arithmetic Hi Jens, On Wed, 12 Feb 2014 21:11:21 -0700, Jens Axboe wrote: > On 2014-02-12 11:25, Daniel Gollub wrote: > > ../parse.h: In function ‘void* td_var(thread_options*, fio_option*, > > unsigned int)’: ../parse.h:110:10: warning: pointer of type ‘void > > *’ used in arithmetic [-Wpointer-arith] ../parse.h:112:9: warning: > > pointer of type ‘void *’ used in arithmetic [-Wpointer-arith] > > I bet there are a lot of these, or other similar code that would > prevent compiling with g++.

I do not try to compile entire fio with g++. If I include fio.h in the external ioengine, parse.h gets included by fio.h or so and causes this g++ warning. This was the last warning (which just got introduced 2 days ago) when fio.h gets included by an external engine build with g++. So the value here is to build external ioengines against libraries/APIs which are only available in C++. In my case against an internal library of CEPH. -- Daniel Gollub -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
