(Although 76 fail is pretty bad, there are still 519 passes)
<jbjnr>
aha. Looking at the fail outputs, I'd say that I didn't get the LD_LIBRARY_PATH right to pick up the components that were built as part of testing. The compilation was done on laptop and binaries copied across with some path name changes.
<jbjnr>
so probably not as bad as 76 fails really

<simbergm>
heller: cool!
<simbergm>
did everything build successfully?
<simbergm>
also, reminder about circleci/stellarbot ;)
<simbergm>
gah, I keep misreading who writes messages
<simbergm>
jbjnr: cool!
<simbergm>
is this where you run martycam?
<jbjnr>
Everything builds ok, but I spent a bit too long setting up the compiler toolchain, cos I wanted to try gcc 8 on the pi
<simbergm>
and it was problematic I guess?
<jbjnr>
Tonight I will try again with the fixes to the LD_LIBRARY_PATH etc
<jbjnr>
looks like many thread suspend tests segfault
<jbjnr>
problematic - yes I had issues with the libstdc++.so.6 and stuff like that, but It seems ok now
<simbergm>
yep...
<simbergm>
ok
<jbjnr>
the thread suspend ones are yours?
<simbergm>
yeah, at least the ones under tests.unit.resource
<simbergm>
I've no clue what could be going wrong there though
<jbjnr>
ok. I'll have to rebuild in debug mode and see what's going on. Was hoping you'd guess immediately what might be wrong :(
<simbergm>
but maybe I should test it at home, there might be a bug that doesn't show up on linux again
<simbergm>
I wish I could do that...
<simbergm>
jbjnr: seems like HWLOC_MEMBIND_BYNODESET was introduced in 1.11.3, and I guess their version macro was messed up around those releases
<simbergm>
I'll just check for < 2 to do it the old way
<jbjnr>
have fun
<simbergm>
I will!
<simbergm>
(I do hate the macros as much as you do, but the world changes slowly...)
<simbergm>
(#ifdefs)
<jbjnr>
I would quite like to cmakeify hwloc and just build it as part of hpx :)
<jbjnr>
(and jemalloc)
<simbergm>
some people will love you, others will hate you
<simbergm>
I'm not sure which one I will be yet
* zao
shakes a fist at hwloc
<zao>
jbjnr: Are there any silly cluster vendors that have a very special patched system-provided hwloc? Like I expect Cray to do.
<zao>
Or the Power people.

<simbergm>
I realized...
<simbergm>
have you had time to play with your arm boards?
<jbjnr>
I was pondering on the way to work whether I could setup a cross compiler toolchain on another machine and build nightlies that coukd then be run on the rpi ...
<jbjnr>
is it worth the effort ...
<jbjnr>
I could buy another pi and have it here at work! that'd simplify things :)
<jbjnr>
quick ebay ....
<heller>
i have 16 arm boards here
<heller>
and the cross compilation setup
<heller>
i just need to find the time to integrate it into our testing ;)
<jbjnr>
ooh. I forgot you had tons
<jbjnr>
got any spare?
<jbjnr>
simbergm: I should have the hpx/opencv stuff running on the pi soon too :)
<simbergm>
jbjnr: nice
<simbergm>
I guess opencv already compiles without problems on arm?
<jbjnr>
not tested yet, but will try today. Can set a build going now as the cross compiler is on the laptop

jbjnr: you can order the suitcase for 650 euros ;)
<jbjnr>
what have you demonstrated on the suitcase arm box?
