Hi, Jayesh,<BR> <BR>Thanks a lot for your reply. Solution 1) works
well on the Win64 machine.<BR>"<BR><FONT face=Arial color=#0000ff>However
we don't ship the gcc libs, *.a, with 64-bit version of MPICH2. Let me know

comflicts with mingw dll's, and also about the performance cost of using cygwin

working.<BR> <BR>Many thanks for your help<BR> <BR>T.<BR><BR>

<DIV dir=ltr align=left><FONT face=Arial color=#0000ff><SPAN

<DIV dir=ltr align=left><FONT face=Arial color=#0000ff><SPAN
class=EC_EC_049304215-05012009>1) Use 32-bit version of MPICH2 on your 64-bit
windows machine (Uninstall any 64-bit version of MPICH2 before you install
32-bit version of MPICH2). AFAIK Cygwin distributions are 32-bit and we provide
default support for Cygwin+gcc on 32-bit platforms only.</SPAN></FONT></DIV>
<DIV dir=ltr align=left><FONT face=Arial color=#0000ff><SPAN
class=EC_EC_049304215-05012009>2) Let us know if you want to build 64-bit
binaries using MPICH2+MingW (The defns for windows fixed width ints - __int* -
is in _mingw.h, which is included by all MingW header files. So include
<sys/types.h> before including "mpi.h" and you should be able to get rid
of errors with undefined MS-extended types. However we don't ship the gcc libs,
*.a, with 64-bit version of MPICH2. Let me know if you need them.).

on windows (without using Visual Studio compiler) try compiling MPICH2
using Cygwin. Let us know if it works for you (We regularly test MPICH2+Cygwin.
You won't have the problem with unsupported poll() if you use Cygwin - Cygwin
libs do the abstraction for you.).</SPAN></FONT></DIV>

<DIV></DIV>Hi,<BR> <BR>Thanks a lot for your reply. <BR>I just read an
infinitely long post that discusses whether __int64 is dead, and realized that I
get into something taboo regarding ms specific vs c99. <BR>There is a
lot of discussion of aethetics there, ..., to no avail though.<BR> <BR>Just
for the sake of the problem, I used the binary distribution for Win64. Below is
my MPICH2/lib <BR>$ ls /c/MPICH2/lib/<BR>TraceInput.lib
fmpe.lib irlog2rlog.lib
mpi.lib<BR>cxx.lib
fmpich2.lib mpe.lib
rlog.lib<BR> <BR>In the win32 version, I did see libmpi.a in the same
folder. But I tried removing that file, and was able to compile and
link.<BR> <BR>My last effort was to use <BR>typedef long long
MPI_Aint<BR>and go back to mingw+gcc3.4.5+vista64, and the error message
was:<BR> <BR>$ gcc -I /c/MPICH2/include/ test.c -L /c/MPICH2/lib/
-lmpi <BR>C:/Users/ting/AppData/Local/Temp/cciBiEaP.o:test.c:(.text+0x38):

status<BR> <BR>As a side note, I tried to compile one from source using
mingw under Win64, <BR>but it was complaining about missing poll() function etc.
Somebody complained in a MingW list, but a mingw person believes that MPI under
windows shouldn't<BR>use poll() anyways. I tried to add some other code
downloaded from the internet that fakes a poll(), then I got a problem with
threads. And I realized that the job is<BR>beyond a novice like
me.<BR> <BR>Thanks again for your help,<BR>hope some day this problem will
disappear. But maybe the mingw idea was wrong -- a minimal set of unix functions
with native winxx impl. Lovely little piece that brings <BR>unix to the dull
windows command line though.<BR> <BR> <BR>T.<BR><BR><BR><BR>> Date:

exit status<BR>> ><BR>> <BR>> You said that you downloaded the
binary distribution, correct? I have no <BR>> experiences with MPICH2 on
Windows<BR>> but I would suspect that the libraries were build with
Microsofts C/C++ <BR>> compiler cl and on Win64 the MingGW gcc<BR>>
compiler and cl are not compatible. __int64 is a Microsoft specific <BR>>
extension to C/C++
(http://msdn.microsoft.com/en-us/library/29dh1w7z.aspx).<BR>> Also it seems
that gcc does some sort of name-mangling (adding an <BR>> underscore to the
function name). This is rather strange<BR>> for a C compiler...<BR>>
<BR>> Probably you'r right that its a gcc 4.3 issue. Maybe some else has more
<BR>> insight into this.<BR>> <BR>> Interestingly he doesn't say that
he can't find libmpi.a. Are you sure <BR>> that it is not there?<BR>>
<BR>> BTW: typedef long MPI_Aint might be a problem because sizeof(long) = 4
<BR>> on Windows at least with the Microsoft compiler. Don't know
what<BR>> gcc does in this situation.<BR>> <BR>> Dorian<BR>>
