that's not surprising, we've had all kind of MPI related issues before
<gonidelis[m]>
hkaiser: yt?
<hkaiser>
here
<hkaiser>
gonidelis[m]: it's late for you ;-)
<gonidelis[m]>
hkaiser: haha ... I happen to be on the country by the sea so it's good time for coding. Why did you use `get_second_element` on your copy CPO adaptation?
<hkaiser>
because the implementation returns an in_out_result, but the algorithm API returns the 'out' part only (the second element)
<gonidelis[m]>
hkaiser: is this defined in the standard? i mean the API return?

I'm updating the docs with more recent versions, does anyone know which generator (version of visual studio) to use for cmake on windows like ` cmake -G "Visual Studio 9 2008"` but 2008 seems to be a bit outdated
<rori>
?*
<zao>
rori: For current VS, it'd be something like: `-G "Visual Studio 16 2019" -A x64`
<rori>
thanks :)

is someone still trying the releases on xeon phi?

x64 is the default for the 2019 vs generator

Oh I'm on manylinux docker and it doesnt allow compiling anything with new ABIs. CXXABI_1.3.7 and GLIBCXX_3.4.19 are maximum supported versions on the sustem
<K-ballo>
the code _could_ be made to work with C++98's std::string, at least in this instance, but I doubt such a thing is worth it

kale[m]: that's the bug you are hitting ^
<kale[m]>
K-ballo: Thanks! I'm not going for the manylinux approach, since no one is going to use Phylanx on an ancient machine. And we have a wheel that works on any recent linux system :)

hkaiser @patrick The arm machine is onsite in stony brook Unit now, in theory, access will be sent around next two weeks.
<hkaiser>
weilewei: nice! thanks for asking
<weilewei>
hkaiser yea, sure, my pleasure.

nice!

gnikunj[m]:yt?
<gnikunj[m]>
akheir here
<akheir>
which problem again? the file system or sudo?
<gnikunj[m]>
File system
<gnikunj[m]>
Sudo works fine
<akheir>
I'll look into it.
<gnikunj[m]>
Thanks! Also could you try building hpx? There seems to be a weird error that I can't reproduce on my local machine
<akheir>
let me look
<gnikunj[m]>
Thanks a lot!
<akheir>
how do you build HPX on rpi? which compiler and flag you use?
<gnikunj[m]>
Not on rpi. Hpx is not building on x86
<gnikunj[m]>
I tried on head node and medusa
<akheir>
again which compiler and which flags?
<gnikunj[m]>
I have the standard set of modules included and use:
<gnikunj[m]>
mkdir build && cd build && cmake .. && make -j $(nproc)
<akheir>
which modules did you load?
<gnikunj[m]>
I use gcc 9.3
<gnikunj[m]>
Gcc 9.3, boost 1.73 release, hwloc 2.2 are the most important ones I believe
<gnikunj[m]>
Let me share the exact config wait.
<nanmiao11>
gnikunj[m] I have built hpx 5 days before
<nanmiao11>
Then, I am not sure what is the problem...
<gnikunj[m]>
they issue seems orthogonal to stable vs master in my opinion. But I'll give it a shot wait
<gnikunj[m]>
nanmiao11: yup stable doesn't help in building either
<gnikunj[m]>
I'll try with clang. It may help
<akheir>
gnikunj[m]: Fixed the Pis. Something stupid goes on Ubuntu server. Whenever this happened just do `sudo reboot`
<gnikunj[m]>
akheir: alright thank! Also, I think ik why hpx is not installing. I have a stupid export that adds hwloc path
<gnikunj[m]>
and even though the path is appended to LD_LIBRARY_PATH, it seems to be confused between selecting one
<akheir>
hmm, could be.
<gnikunj[m]>
I'm trying to rebuild now. If it doesn't build I'll let you know
<gnikunj[m]>
akheir: it works now. I don't know why it would confuse when there's a clear order to it :/

<akheir>
many times cmake has its own ideas. This is not the first time we ran into this issue. That's why we try to minimize system installed libraries and exclusively use modules
<gnikunj[m]>
Makes sense

hkaiser I plan to run experiment/benchmark these days, and plan to use 1.5.0-rc1 for now. Any suggestions?
