<gonidelis[m]> hkaiser: meeting in one hour ?
<hkaiser> uhh
<hkaiser> I thought we would meet now, but I think I'm confused by the DST time difference again
<gonidelis[m]> ok the time change has made a mess
<gonidelis[m]> again
<gonidelis[m]> created*
<hkaiser> would you have time now?
<gonidelis[m]> now it's fine
<gonidelis[m]> of course
<gonidelis[m]> sorry
<hkaiser> ok, let's do it now, then
<gonidelis[m]> in case you are in, i am in too. so i might have a wrong link ;p

<hkaiser> parsa: do you want to meet today?
<parsa> hkaiser: yeah. i did think katie cancelled today though
<hkaiser> ok
<shahrzad> hkaiser: I think I fixed the circular dependency issue I had in my branch but there are still some test failing which are unrelated: https://github.com/STEllAR-GROUP/hpx/runs/1330356848
<hkaiser> shahrzad: ok, thanks - I'll have a look
<shahrzad> also this is the error I get recently building hpx with examples: https://gist.github.com/scheherzade/d858474f42e54b52c7f2d63f48af502b
<hkaiser> shahrzad: yah, that's what Patrick told me yesterday, would yo mind creating a ticket for this?
<shahrzad> hkaiser:sure I'll do that.

<gonidelis[m]> K-ballo: yt?
<K-ballo> gonidelis[m]: here now
<gonidelis[m]> again on this error
<gonidelis[m]> you commented that: "there is nothing to be invoked"
<K-ballo> what would that even mean?
<gonidelis[m]> come again?
<K-ballo> there's a target callable right there
<K-ballo> that's what's to be invoked
<gonidelis[m]> updated the gist
<K-ballo> same answer
<K-ballo> the thing to be invoked was in the first gist
<gonidelis[m]> you mean that there is sth in `std::forward<F>(f)`'s and `first`'s place
<K-ballo> ?
<K-ballo> I have no idea how to interpret "there is nothing to be invoked"
<K-ballo> there obviously is something there
<gonidelis[m]> sec
<gonidelis[m]> K-ballo: I was wrong. Sorry
<gonidelis[m]> you said "sounds like `f` isn't callable with `first` "
<gonidelis[m]> my bad
<gonidelis[m]> apologies
<K-ballo> ok, that makes more sense
<gonidelis[m]> uhhh... does master compile fine?
<gonidelis[m]> for you guys^^
<K-ballo> yes
<K-ballo> what's the lambda in question?
<gonidelis[m]> i am 90% sure that it is `[](std::size_t v1, std::size_t v2`
<gonidelis[m]> anyways that's the call
<gonidelis[m]> let me give you my link tho
<K-ballo> how will that ever match a projected invocation for a single iterator?
<K-ballo> the projected invocation of that lambda would have to involve two iterators, no?
<gonidelis[m]> what `transfomr` impl are you looking at?
<K-ballo> none
<K-ballo> I'm looking at the error message, the original revision, and the lambda you just linked to
<gonidelis[m]> let me double check
<K-ballo> invoke(hpx::parallel::v1::detail::transform_projected<__gnu_cxx::__normal_iterator<long unsigned int*, std::vector<long unsigned int> >, test_transform_binary_exception(ExPolicy, IteratorTag) [with ExPolicy = hpx::execution::parallel_policy; IteratorTag = std::random_access_iterator_tag]::<lambda(std::size_t, std::size_t)> >, test::test_iterator<__gnu_cxx::__normal_iterator<long unsigned int*, std::vector<long unsigned int> >,
<K-ballo> std::random_access_iterator_tag>&)’
<K-ballo> that lambda definitely isn't callable with a single argument, it needs two (and of the right kind)
<bita_> hkaiser, meeting?
<gonidelis[m]> ok first of all again master won't compile for some reason
<gonidelis[m]> I `git fetch upstream
<gonidelis[m]> `git rebase upstream/master`
<gonidelis[m]> and get `Current branch adapt_transform is up to date.`
<K-ballo> fwiw that doesn't mean master doesn't compile, it means adapt_transform doesn't compile
<gonidelis[m]> K-ballo: adapt_transform completely follows master as you can see from the message though
<K-ballo> what's your interpretation of "follows"?
<gonidelis[m]> is up to date
<K-ballo> being up to date means there are no commits in master that aren't in adapt_transform
<K-ballo> unless there also arent any commits in adapt_transform that aren't in master, then you are building adapt_transform and not master
<gonidelis[m]> i created adapt_transfomr 5 minutes ago
<gonidelis[m]> no extra commits there
<K-ballo> that's new information
<K-ballo> no extra working dir changes either?
<gonidelis[m]> what do you mean
<gonidelis[m]> ?
<K-ballo> uncommited changes
<gonidelis[m]> i was on master when I `git worktree add ../adapt_transform`
<gonidelis[m]> let me hcekc
<gonidelis[m]> chekc*
<gonidelis[m]> check**** grr
<K-ballo> that's also new information
<K-ballo> in any case, if you truly are building master and it doesn't compile, there must come in the form of a compiler error message
<gonidelis[m]> yeah that's a huge error message
<gonidelis[m]> K-ballo:
<gonidelis[m]> any ideas?
<zao> Linker errors are nice.
<K-ballo> someone mentioned those earlier today
<gonidelis[m]> i am using make
<gonidelis[m]> instead of gmake
<ms[m]> freenode_gonidelis[m]: sorry about that, it's very recent: https://github.com/STEllAR-GROUP/hpx/issues/5035
<gonidelis[m]> i just wanted to know it's now my fault
<gonidelis[m]> ms[m]: thanks a lot
<gonidelis[m]> shoud i try `cmake HPX_WITH_EXAMPLES=off`?
<ms[m]> depends what you want to do
<ms[m]> if your changes don't really affect the examples you can just not build them
<ms[m]> most likely some tests will also fail to link
<ms[m]> if this is for your algorithm adaptations you might be unaffected by these errors
<ms[m]> or if you really need to build everything you can likely go back a week or so (I haven't checked exactly when this was introduced)
<gonidelis[m]> ms[m]: yeah I am still trying to adapt transform so I will be fine
<gonidelis[m]> thanks!
<gonidelis[m]> :)
<hkaiser> ms[m]: would you have the time to look into #5035?
<hkaiser> it happens with newest gcc and release mode only
<ms[m]> hkaiser: yeah, I'll try to have a look tomorrow
<hkaiser> ms[m]: thanks a lot!
<gonidelis[m]> ms[m]: `HPX_WITH_EXAMPLES=Off`doesn't seem to work I will try an odler version
<K-ballo> there's a -D in there, right?
<gonidelis[m]> oups
<gonidelis[m]> !
<gonidelis[m]> :)
<gonidelis[m]> i am fully rusty
