Hi,
We need to update the code required to generate the gcc libs for a 64-bit
version of the libs. Are you planning to create 64-bit binaries using gcc
?
I will take a look at the effort required for the change and let you know
if we can push it into the upcoming release candidate.
Regards,
Jayesh

Hi, Jayesh,
I was trying the new 1.08p1 version of MPICH2 on Windows Vista64. I heard
from you that we need the gcc libs, *.a, with 64-bit version
Could you please send a copy of that to me or somehow make it available
online?
Many thanks for your help!

Hi, Jayesh,
Thanks a lot for your reply. Solution 1) works well on the Win64 machine.
"
However we don't ship the gcc libs, *.a, with 64-bit version of MPICH2.
Let me know if you need them.).
"
also, could you please make the gcc libs *.a available somehow?
I didn't try cygwin because I heard about comflicts with mingw dll's, and
also about the performance cost of using cygwin vs. mingw. But it's only
rumors, I don't really know if there is any big performance impact.
Currently, I am happy with MPICH2+mingw working.
Many thanks for your help
T.

Hi,
Glad to know MPICH2+MingW is working for you in 32-bit windows.
There are two ways to fix your problem with MPICH2+MingW on 64-bit
windows,
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.
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.).
If you want to compile MPICH2 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.).
Let us know the results.
Regards,
Jayesh

Hi,
Thanks a lot for your reply.
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.
There is a lot of discussion of aethetics there, ..., to no avail though.
Just for the sake of the problem, I used the binary distribution for
Win64. Below is my MPICH2/lib
$ ls /c/MPICH2/lib/
TraceInput.lib fmpe.lib irlog2rlog.lib mpi.lib
cxx.lib fmpich2.lib mpe.lib rlog.lib
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.
My last effort was to use
typedef long long MPI_Aint
and go back to mingw+gcc3.4.5+vista64, and the error message was:
$ gcc -I /c/MPICH2/include/ test.c -L /c/MPICH2/lib/ -lmpi
C:/Users/ting/AppData/Local/Temp/cciBiEaP.o:test.c:(.text+0x38): undefined
reference to `MPI_Init'
C:/Users/ting/AppData/Local/Temp/cciBiEaP.o:test.c:(.text+0x4b): undefined
reference to `MPI_Comm_rank'
collect2: ld returned 1 exit status
As a side note, I tried to compile one from source using mingw under
Win64,
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
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
beyond a novice like me.
Thanks again for your help,
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
unix to the dull windows command line though.
