<div class="moz-cite-prefix">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)?<br>
<br>
If you check siteconfig's recommendation, -lpthread in LDFLAGS
should be changed to -pthread.<br>
<br>
As you can see on the website at:<br>

<br>
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.<br>

<div> Sorry for the late reply to the above

we are still getting an error regarding segmentation fault,

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 [ <a moz-do-not-send="true"

<br>
Maybe, the segmentation fault is related to Xeon Phi
coprocessors, but I don't have experience using a Xeon Phi
coprocessor.

Dear wien2k users,<br>
<br>
We are trying to install wien2k in a server with
Red Hat Linux. The compiler used for the installation
is composer_xe_2015.0.090<br>
<br>
Two errors were appeared during installation as being
seen from compiler.msg<br>
<br>
1) X86_64-K1om-linux-ld: No such file or
directory......Error 100<br>
<br>
2) segmentation fault (core dumped)........Error 2<br>
<br>
I am giving the settings of OPTION below<br>
<br>
current:FOPT:-FR -mp1 -w -prec_div -pc80 -pad -ip
-traceback<br>
current:LDFLAGS:$(FOPT)

Any response in this regard will be helpful for us.<br>
