    <p>I am trying to compile a software package called FDMNES for X-ray Absorption Spectra Modelling with MPI for the first time in Windows, using Visual Studio 2010 and a trial version of the Intel Composer XE 2011 SP1, ifort visual fortran compiler in conjunction with Intel Parrelel Studio 2011. I have managed to get all the object files compiled using the 64-bit version of ifort, but when it comes dime to link the files I recieve the followed error:</p> <pre><code>1&gt;------ Build started: Project: Console2, Configuration: Release x64 ------ 1&gt;Linking... 1&gt;main.obj : error LNK2019: unresolved external symbol MPI_INIT referenced in function MAIN__ 1&gt;main.obj : error LNK2019: unresolved external symbol MPI_COMM_SIZE referenced in function MAIN__ 1&gt;main.obj : error LNK2019: unresolved external symbol MPI_COMM_RANK referenced in function MAIN__ 1&gt;general.obj : error LNK2019: unresolved external symbol MPI_BCAST referenced in function RESEAU 1&gt;potential.obj : error LNK2001: unresolved external symbol MPI_BCAST 1&gt;main.obj : error LNK2001: unresolved external symbol MPI_BCAST ......etc 1&gt;x64\Release\Console2.exe : fatal error LNK1120: 7 unresolved externals 1&gt; 1&gt;Build log written to "file://C:\Users\Arturo\Documents\Visual Studio 2010\Projects\Console2\Console2\x64\Release\BuildLog.htm" 1&gt;Console2 - 18 error(s), 0 warning(s) ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== </code></pre> <p>I've tried linking to the 64bit Intel MPI libraries, as well as MPICH2 64bit libraries by adding the command /L"C:\PathtoMPILibrary\" but to no avail. I have also tried using this makefile, running with gmake from a mingw32 package:</p> <pre><code>#Make file for the fdmnes package objects = main.obj clemf0.obj coabs.obj convolution.obj dirac.obj fdm.obj fprime.obj general.obj hubbard.obj lecture.obj mat.obj metric.obj minim.obj potential.obj scf.obj selec.obj spgroup.obj sphere.obj sub_util.obj tab_data.obj tddft.obj tensor.obj compiler = mpif90 -O3 -c fdmnes_mpi : $(objects) mpif90 -o fdmnes_mpi $(objects) main.obj : main.f $(compiler) main.f clemf0.obj : clemf0.f $(compiler) clemf0.f .....etc </code></pre> <p>But when I run gmake, I get the following error:</p> <pre><code>Intel(R) Visual Fortran Intel(R) 64 Compiler XE for applications running on Intel(R) 64, Version 12.1.0.233 Build 20110811 Copyright (C) 1985-2011 Intel Corporation. All rights reserved. ifort: error #10037: could not find 'link' </code></pre> <p>I've exhausted forums, and I need this to be compiled with MPI under 64bit windows. Any help would be very much appreciated! Thanks.</p>

    1. COThe first error message you've posted indicates that while the compiler found the MPI header files (otherwise you would've not gotten past the compiling stage), your linker cannot find the actual MPI library. Make sure your MPI library is correctly installed and that the linker is supplied with the right path.

    2. COHave you actually added the library to the project? It is not enough just to add the path to library you have to specify that it needs to be linked to also.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
