Dear All,<br><br>       On one of our shared memory machines, openmpi is compiled with gfortran. As ifort is also installed on the machine, so I requested system administrator <br>to build and install openmpi with ifort.  I got reply that I can use the same openmpi installation with ifort by using -openmpi flag with ifort like<br>
<br>ifort -openmpi<br><br>I tried the by replacing &quot;ifort&quot; with ifort &quot;-openmpi&quot; in Makefile_IFC8 in Main Directory. Compliation was OK but got lot of errors at linking stage like:<br><br>bdyin.o: In function `bdyin_&#39;:<br>
bdyin.f:(.text+0x47c): undefined reference to `mpi_abort_&#39;<br>bdyin.f:(.text+0x608): undefined reference to `mpi_abort_&#39;<br>bdyin.f:(.text+0xf70): undefined reference to `mpi_bcast_&#39;<br>bdyin.f:(.text+0xfb2): undefined reference to `mpi_scatter_&#39;<br>
bdyin.f:(.text+0x1431): undefined reference to `mpi_sendrecv_&#39;<br>bdyuv.o: In function `bdyuv_&#39;:<br>.....................<br>..................<br>..................<br>Any idea.<br>Thanks in advance<br>Imran<br><br>
