Hello,<div><br></div><div>I have the latest OpenMPI on linux which I compiled with the Intel compiler suite. I am trying to compile an OpenMPI application. My particular application uses RInside and RcppEigen. If I comment out the openMPI parts of my code, the compile string is:</div>

<div><br></div><div>icpc -I/usr/share/R/include -I/usr/lib/R/site-library/Rcpp/include -I/usr/local/lib/R/site-library/RInside/include -O3 -pipe -g -Wall  -I/usr/local/lib/R/site-library/RcppEigen/include   sjb_simple_smle_with_Rinside.cpp  -L/usr/lib/R/lib -lR  -lblas -llapack -L/usr/lib/R/site-library/Rcpp/lib -lRcpp -Wl,-rpath,/usr/lib/R/site-library/Rcpp/lib -L/usr/local/lib/R/site-library/RInside/lib -lRInside -Wl,-rpath,/usr/local/lib/R/site-library/RInside/lib  -o sjb_simple_smle_with_Rinside</div>

<div><br></div><div>Thus, I tried to compile with mpic++ using:</div><div><br></div><div>mpic++ -I/usr/share/R/include -I/usr/lib/R/site-library/Rcpp/include -I/usr/local/lib/R/site-library/RInside/include -O3 -pipe -g -Wall  -I/usr/local/lib/R/site-library/RcppEigen/include   sjb_simple_smle_with_Rinside.cpp  -L/usr/lib/R/lib -lR  -lblas -llapack -L/usr/lib/R/site-library/Rcpp/lib -lRcpp -Wl,-rpath,/usr/lib/R/site-library/Rcpp/lib -L/usr/local/lib/R/site-library/RInside/lib -lRInside -Wl,-rpath,/usr/local/lib/R/site-library/RInside/lib  -o sjb_simple_smle_with_Rinside</div>

<div><br></div><div>If I uncomment</div><div>#include &quot;mpi.h&quot;</div><div><br></div><div>and try to compile, I get the errors below. Is there any trick to compiling OpenMPI applications with the Intel compilers?</div>
