[MPICH] Compiling and using under WinXP/cygwin - use lib*.a in MPICH2\lib

[Jayesh Krishna]

Hi,

>>>> 1-Can you send me a procedure ?
	Just remove the MPICH2 install directory under cygwin (or modify the
PATH accordingly). Install MPICH2 using the MSI installer.
>>>> 2-I will be able to compile other programs under cygwin if MPICH2 it is
not installed under cygwin?
	As I mentioned in my previous email, "You should make sure that you
use the libraries (lib*.a)provided with the windows installation of MPICH2
(in MPICH2\lib) when compiling your program under cygwin (if you want to run
the program using the windows version of MPICH2)." You are provided a set of
libraries, MPICH2\lib\lib*.a, with the MPICH2 installation (MSI
installation) to be used with cygwin gcc. See the windows developer's guide
for more details
(http://www.mcs.anl.gov/research/projects/mpich2/documentation/index.php?s=d
ocs).

Regards,
Jayesh

Hi,..

I am sure I use the mpiexec from MSI, but however with the mpiexec from
cygwin I obtain the same result.

smpd.exe -status, say me,
"smpd running on NOHW8156"

Well. I think will be necessary to remove the installation of MPICH2 from
cygwin and remain only with the installation from msi.

1-Can you send me a procedure ?
2-I will be able to compile other programs under cygwin if MPICH2 it is not
  installed under cygwin?
