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

[Jayesh Krishna]

 Hi,

>>>I remove c:\cygwin\home\yo\MPICH2\... Then, I am not able to compile
under cygwin

	mpicc is a script provided with MPICH2 installation to compile MPI
programs. You should use gcc/g++ directly to compile programs after removing
the MPICH2 installation.

>>>...found under c:\Program Files\MPICH2\lib\ must be copied under cygwin?

	You can access the files in windows without copying them.
(/cygdrive/c/Progra~1/MPICH2/lib)

Regards,
Jayesh

I remove c:\cygwin\home\yo\MPICH2\
and remove the related information in $PATH I erase also all the build
directory ...Then, I am not able to compile under cygwin

This is the output,

BE04845 at NOHW8156 /tmp/mpi/mpich2-1.0.6p1/examples $ make cpi ../bin/mpicc
-I../src/include -I../src/include -O2  -c cpi.c
make: ../bin/mpicc: Command not found
make: *** [cpi.o] Error 127

In mpich2-doc-windev.pdf they are not any information about compiling under
cygwin

When you say "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...."

It seems that the files,
libfmpich2g.a
libmpi.a
libmpicxx.a
found under c:\Program Files\MPICH2\lib\ must be copied under cygwin?

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?
