Hi all,<br><br>I am trying to compile an application developed in C++ with Intel 10.1.008 (64bits).<br><br>First of all, I am not using C++ bindings for MPI.<br>For that reason, I got the same error discussed recently and I solved it defining MPICH_SKIP_MPICXX before mpi.h include.<br>
<br>After this step, I got the following problem while linking the application:<br><span style="font-family: courier new,monospace;">/usr/local/mpich2/lib/libmpich.a(helper_fns.o): In function `MPIR_Localcopy&#39;: helper_fns.c:(.text+0x6b3): undefined reference to `_intel_fast_memcpy&#39;</span><br style="font-family: courier new,monospace;">

<br>What is </span><span style="font-family: courier new,monospace;">_intel_fast_memcpy? Is it some bad configuration in compilation options?</span><br><span style="font-family: courier new,monospace;"><br>Have someone faced such kind of problem before?<br>
Any hint about how to solve it?<br><br>Thanks in advance,<br>LC<br></span>
