<akheir> k-ballo: they are in there in /opt/boost ;-)
<akheir> k-ballo: I had to remove some old compilation to make room for new ones
<akheir> k-ballo: sorry if it made your scripts go bad
<K-ballo> akheir: thanks, figured it out, just had to tweak the BOOST_ROOT paths
<aserio> mbremer: he just got out of a meeting
<K-ballo> I was still using whatever was "most recent" back when I configured the build
<aserio> I will poke him for you
<mbremer> @aserio: Thanks! It's about the ittnotify stuff.

<diehlpk_work> Not even as a preprint or tech report?
<hkaiser> no, just submitted to a conference
<diehlpk_work> I added octotiger stuff as a techreport oin the references

<mbremer> @hkaiser: I talked with @K-ballo about some issues I was having building hpx with ittnotify on ( see here: https://gist.github.com/bremerm31/0d302cec5bf7e30206fe29b707bfc769 ). I was wondering if you could tell if this is an hpx error or a me error?
aserio has joined #ste||ar
<aserio> zbyerly, zbyerly_: yt?
<hkaiser> mbremer: let me investigate - would you mind creating a ticket for this?
<hkaiser> it's most probably an hpx error
<mbremer> Sure thing! My guess it should be easy to reproduce, since it seems like it's just a question of building with ittnotify on. I'll create a ticket. Let me know if theres' anything I can do to help. Thanks!!
vamatya__ has quit [Ping timeout: 240 seconds]
<hkaiser> mbremer: thanks a lot, I'll check this out later today
<K-ballo> from what I could see, some itt::string_handle wasn't fully integrated with hpx::function and such
<K-ballo> on unrelated news, I finally ran into errors due to missing -pthread after a clean build on rostam

<hkaiser> akheir: see K-ballo's message above ^^
<K-ballo> it might have been my fault, I have no idea
<akheir> k-ballo: could you elaborate.
<K-ballo> akheir: not much.. I did a clean build on a branch and ended up with unresolved pthread symbols when building libhpx.so, so I added the flag (which I might or might not have been supposed to add when we switched away from boost.thread)

<K-ballo> hkaiser, akheir: it's definitively my fault, doesn't happen on master, only on my std-random branch
<K-ballo> we must be getting -pthread implicitly from boost.random which somehow gets linked (even though it is not used for core)
aserio has quit [Ping timeout: 264 seconds]
<hkaiser> k-pthread is just set in SetupBoost - no other place where we even mention it
EverYoung has quit [Ping timeout: 264 seconds]
<hkaiser> K-ballo: ^^
<K-ballo> hkaiser: somehow core hpx links against boost.regex, boost.regex depends on boost.thread, FindBoost.cmake kicks in and we inherit -pthread
<hkaiser> ok, makes sense
<K-ballo> that's why everything was "working" before, regex
<K-ballo> ehm, s/regex/random
EverYoung has joined #ste||ar
<hkaiser> k
<K-ballo> but... random does not depend on threads
<hkaiser> right, that's what I thought
<hkaiser> we #include <pthread.h> in some places
<hkaiser> not sure if that's a problem
<K-ballo> darn, I thought I'd finally figured it out
<K-ballo> somehow taking boost.random out results in pthread linking errors
<hkaiser> what symbols are missing and where are those refrenced from?
<K-ballo> I'll post those in a few minutes, I need to build from scratch
Matombo has joined #ste||ar
<K-ballo> the diagnostic ought to be the same still, somehow we are inheriting -pthread (or at least -lpthread) via boost.random
<hkaiser> K-ballo: so asio needs
<hkaiser> it
parsa has joined #ste||ar
zbyerly_ has joined #ste||ar
<hkaiser> and std::thread needs it as well
<hkaiser> K-ballo: but we forcefully add -pthread to the compiler command line in SetupBoost - do we need to add -lpthread to the linker as well?
<K-ballo> no, -pthread adds -lpthread
<zao> (FreeBSD clang++ needs -pthread for std::thread, btw)
<zao> At least for linking, compiling seems "fine".
<K-ballo> hkaiser: why are we forcefully adding -pthread in SetupBoost??
<zao> I can't wait for this to break the poor sods on mingw :)
