05:22 <nikunj> why does this CMakeLists have thread_pool_executor_1114 in the tests set? link: https://github.com/STEllAR-GROUP/hpx/blob/master/tests/regressions/threads/CMakeLists.txt

05:22 <nikunj> ^^not have

05:23 <nikunj> is it by mistake or for a reason?

05:24 <nikunj> wait it has it, a reading mistake from my side

07:05 <M-ms> jakub_golinowski: thanks, will have a look today

07:29 <M-ms> jakub_golinowski: where is HAVE_TBB set in cmake? HAVE_HPX should preferably be set the same way

13:27 <M-ms> jakub_golinowski: could you also update the ifdef around #include hpx_main

13:28 <jakub_golinowski> M-ms, here

13:28 <jakub_golinowski> M-ms, where exactly? in test_main?

13:29 <M-ms> did you see my question about HAVE_HPX/HAVE_TBB earlier?

13:30 <M-ms> jakub_golinowski: yep

13:30 <jakub_golinowski> M-ms, I did not see any message before now, checking the log right now

13:38 aserio has joined #ste||ar

13:41 AnujSharma has quit [Ping timeout: 268 seconds]

13:45 <M-ms> jakub_golinowski: ok, no problem

13:46 quaz0r has joined #ste||ar

13:46 <jakub_golinowski> M-ms, to answer your question from before: HAVE_HPX is already set in the analogous way to the HAVE_TBB it is in file /cmake/OpenCVFindLibsPerf.cmake

13:48 <jakub_golinowski> I mean the set(HAVE_TBB... command itself is in another file (cmake/OpenCVDetectTBB.cmake) but we do not have a similar file for HPX so I just do it in the OpenCVFindLibsPerf

13:52 <jakub_golinowski> M-ms, but I still do not understand what do you mean by updating the #ifdef around #include hpx_main?

13:52 <M-ms> ok, that's good

13:53 <M-ms> assuming I'm looking at the correct version, you have #ifndef HPX_STARTSTOP include hpx_main...

13:53 <jakub_golinowski> yes

13:53 <M-ms> if you're using another non-hpx backend I guess HPX_STARTSTOP is not going to be defined

13:54 <jakub_golinowski> damn

13:54 <M-ms> :)

14:09 <jakub_golinowski> M-ms, is sth like this safe for all compilers:

14:09 <jakub_golinowski> #if defined(HAVE_HPX) && !defined(HPX_STARTSTOP)

14:10 <jakub_golinowski> I tested it locally and it behaves as expected for my gcc 5.4.0

19:36 <nikunj> hkaiser: yt?

19:38 <nikunj> zao: yt?

19:38 anushi has quit [Remote host closed the connection]

19:39 <zao> Hi!

19:39 <nikunj> Hi!

19:39 <nikunj> could you please check if the changes I made works on your pc: pr link: https://github.com/stellAR-GROUP/hpx/pull/3357

19:40 <nikunj> The code runs fine on my laptop, but I need to make sure everything works fine.

19:41 <zao> Maybe, let's see what shape the machine is in :)

19:41 <nikunj> thanks :)

19:55 <zao> nikunj: Is there some example or test that I should build?

19:55 <nikunj> you could try tests.unit.actions

19:56 <nikunj> I did not add any tests since there were already plenty to test it from

19:56 <nikunj> or examples.pipeline

19:58 <zao> Alright, kicked off a build, time will tell if it works :P

19:58 <nikunj> hope it works ;)

20:02 <zao> https://gist.github.com/zao/a87712b1d4f82860391ca7a542d04cc0

20:02 <zao> nikunj: ^

20:03 <zao> Not necessarily your problem, but this builds poorly :D

20:03 <nikunj> zao: I'll look into it

20:04 <zao> Seems like -DHPX_WITH_CXX14=ON doesn't end up emitting any -std=c++ in the command line.

20:04 <nikunj> zao: could you please provide the environment and compiler specifications

20:05 <zao> clang version 3.8.1-24 (tags/RELEASE_381/final)

20:05 <zao> debian 9.something

20:05 <zao> cmake ../nik-hpx -G Ninja -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DBOOST_ROOT=/opt/boost-1.65.1-cxx14 -DHPX_WITH_MALLOC=system -DHPX_WITH_CXX14=ON -DHPX_WITH_TESTS=ON -DHPX_WITH_EXAMPLES=ON

20:06 <nikunj> let me try the same cmake specs on my laptop

20:07 <zao> Gonna build regular master.

20:07 <nikunj> zao: do you have gcc installed?

20:09 <zao> No idea, but seems like master builds.

20:10 <zao> How long was it since you last rebased against master?

20:11 <nikunj> this is the last hash: e6c543d6de754ddefc309b7966f291e6d9048bb3 . It's from Jun 15th

20:16 <zao> There's something different between your branch and master, your branch doesn't have any -std=c++14 in the command lines.

20:16 <zao> Not going to try to rebase here inside this horrible container environment :)

20:16 <nikunj> zao: how is it possible :/

20:17 <nikunj> I don't remember messing with any of the options or flags

20:20 <zao> It's possible that it's an underlying problem that's addressed in later commits to master.

20:20 <zao> K-ballo: Does missing -std=c++14 with -DHPX_WITH_CXX14=ON ring a bell?

20:21 <K-ballo> nope

20:21 <K-ballo> could the try compile test have failed?

20:23 <zao> Let'

22:31 <zao> Builds with system GCC in the container.

22:32 <zao> But still, clang's hosed in this build but not the master one.

22:32 <zao> Guess I should try the commit you branched from.

22:33 akheir has quit [Quit: Leaving]

22:36 <zao> How odd, only getting 487-some targets with a regular build.

22:37 <zao> Bah, forgot that invoking ninja doesn't build everything.

22:37 <zao> Have I ever mentioned that the HPX build is very weird?

22:50 <zao> nikunj: Actual failure too with system compiler
