<galabc> Hi I have a question concerning opemMP and Clang
<galabc> From my understanding OpenMP comes with the Clang Compiler
<galabc> But its location is mysterious for me
<galabc> its in /opt/mn/clang/6.0.0/lib/clang/6.0.0/include/
<galabc> On the rostam clusters
<galabc> im not 100% sure why there would be an headers inside of opt/mn/clang/6.0.0/lib directory
<hkaiser> akheir: ^^

<zao> Doesn't sound overly strange, bit of an implementation detail?
<nikunj> hkaiser, I wanted to add documentation for the makefile and also a "how to install hpx". Should I wait for simbergm's pr to merge?
<zao> If you use -fopenmp to clang, the proper headers/libs should be found, as far as I understand it.
akheir has quit [Quit: Leaving]
<nikunj> galabc, yes OpenMP compiled from clang 3.8 iirc
<nikunj> using -fopenmp and listing headers should do
<nikunj> oh, I see zao has already written the same thing xD

<hkaiser> nikunj: can you add it to simbergm's PR?
<nikunj> hkaiser, I guess so
<galabc> The problem is that I am using a custom clang compiler
<galabc> I have to manually link the directories /opt/mn/clang/6.0.0/include and /opt/mn/clang/6.0.0/lib/clang/6.0.0/include/
<hkaiser> galabc: shouldn't your custom compiler know where to look for its headers?
<galabc> Well currently it looks for the headers in the variable $CPLUS_INCLUDE_PATH
<hkaiser> galabc: ok, so what's the problem, then?
<galabc> well when I link the directory /opt/mn/clang/6.0.0/include
<galabc> there is no issue
<hkaiser> ok, good
<galabc> But when I also load /opt/mn/clang/lib/clang/6.0.0/include which is where the omp.h header is located I get errors
<hkaiser> heller__: I separated the optimizations from the thread_local_allocator, pls see #3465
<hkaiser> galabc: you need to build your custom compiler with enabled openmp, did you do that?
<hkaiser> then you should have an omp.h in your include directory, shouldn't you?
<galabc> yes I can try to rebuild my custom compiler with openmp support
<galabc> My temporary solution was to copy the omp.h header in a local directory which is linked when compiling
<galabc> It works but it is not very rigourous
<zao> I'm suspecting it takes more than just headers/libs for the compiler to do remotely the right thing.
