which library should be used in windows with cvf

[雪媛 聂 <nie_xueyuan@…>]

Hello,
    I downloaded mpich2-1.0.8p1-win-ia32 from
http://www.mcs.anl.gov/research/projects/mpich2/ . I followed the steps
described by README.winbin which was generated after the mpich2 installed. If
I compiled and linked the file which only includes the six basic functions, the
file can be compiled and linked successfully. But if my program employed other
functions, such as mpi_scatterv, mpi_gatherv, the link process could be failed.
 
In the projection settings, I already added fmpich2s.lib to the object/library
modules.
 
The error information are as follows,
Linking...
imslmpistub.lib(MPISTUB.obj) : error LNK2005: _MPI_BARRIER@8 already defined in
fmpich2s.lib(fmpich2s.dll)
imslmpistub.lib(MPISTUB.obj) : error LNK2005: _MPI_BCAST@24 already defined in
fmpich2s.lib(fmpich2s.dll)

Debug/automacro.exe : fatal error LNK1169: one or more multiply defined symbols
found
Error executing link.exe.
automacro.exe - 9 error(s), 0 warning(s)
 
I also tried to add fmpich2g.lib to the link option, the same error information
appears.
 
If I only add fmpich2.lib to the link option, link error would be
Linking...
automacro.obj : error LNK2001: unresolved external symbol _MPI_SCATTER@36
automacro.obj : error LNK2001: unresolved external symbol _MPI_SCATTERV@40
automacro.obj : error LNK2001: unresolved external symbol _MPI_GATHERV@40
Debug/automacro.exe : fatal error LNK1120: 3 unresolved externals
 
Could you please help me solve the problems. Now I am puzzled that which
library I should use to make the functions such as mpi_scatterv, resolved ?
 
Thanks a lot.

 Hi,
  The fortran library, fmpich2s.lib, does not work, as expected, with the
Compaq Visual Fortran compiler. I will look into this problem and get back
to you.

Jayesh

Hi,

Can you try the following in CVF ?

# Change the "argument passing convention" to "C, by reference" # Leave the "External Name interpretation" as "Upper Case" # Change the "String length argument passing" to "After all args"

You can find the above settings in "Project" --> "Settings" --> "Fortran" tab --> "External Procedures" category in CVF.

# Add fmpich2.lib as the input "Object library modules" (Remove fmpich2s.lib and fmpich2g.lib from the object library input modules)

Let us know if it works for you. Also it looks like "imslmpistub" is redefining some of the MPI functions (Is the stub lib written by you ? )

Regards, Jayesh
