Hi Gavin why -pthread instead of -lpthread ? The threading library is libpthread and should be linked with -lpthread ! I remembre that I made some ten years ago the remark on that: On SUSE systems (at thae time it was 9.2 and older) one can have a very comfortable setup of the linker such that it finds the standart libraries by itself. You can check it if you remove the -pthread switch from the linker line and find that Wien2k is still linked correctly. If not then you may use ldconfig to make your linker environment more comfortable.
Hi Shamik Below I do not understand why the linker should need the compiler options (LDFLAGS:$(FOPT)) ?? The path to the mkl libraries looks also not standard it seems to point on the PHI libraries, I think you should first start with a regular setup and try afterwards to make a XEON PHI version running (How many PHI's are you using in your system ? I am interested whether the PHI's make sense for Wien) Ciao Gerhard DEEP THOUGHT in D.

Juli 2015 00:50 An: A Mailing list for WIEN2k users Betreff: Re: [Wien] Wien2k installation problem You need to narrow down the cause of the "segmentation fault (core dumped)" error. Perhaps, in a compile.msg file, it shows what program caused the segmenation fault (ifort, gcc or icc)? If you check siteconfig's recommendation, -lpthread in LDFLAGS should be changed to -pthread. As you can see on the website at: http://wiki.rac.manchester.ac.uk/community/XeonPhi/GettingStarted/Compilation It looks like you might want to compile for just the HOST processor by adding -no-offload to your FOPT options before attempting to compile with the Xeon Phi coprocessors.

As the error message says, it cannot find the X86_64-K1om-linux-ld file. I guess that you have to install a redhat package (I would expect that redhat support [ https://access.redhat.com/support/ ] would be able to tell what package needs installed ) or Intel's Manycore Platform Software Stack (MSSP) [ https://software.intel.com/en-us/articles/intel-manycore-platform-software-stack-mpss ] to get the file. I don't see anything noticeable wrong with your compile settings, but it should be better to use the recommended siteconfig settings as there are differences. For example, you don't have -assume buffered_io (or -assu buff), which can be faster [ http://www.mail-archive.com/wien%40zeus.theochem.tuwien.ac.at/msg05711.html ] and prevent NFS problems [ http://www.mail-archive.com/wien%40zeus.theochem.tuwien.ac.at/msg03171.html ]. Maybe, the segmentation fault is related to Xeon Phi coprocessors, but I don't have experience using a Xeon Phi coprocessor.
