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

[Jayesh Krishna]

Hi,
 The command below should be able to compile an MPI program written in C (or
set the appropriate env vars -- see g++ doc for details),

    g++ -I<INCLUDE-DIR> -L<LIB-DIR> icpi.c -lmpi -o cpi_cygwin.exe

(eg:This is what I do, g++ -I/cygdrive/c/Progra~1/MPICH2/include
-L/cygdrive/c/Progra~1/MPICH2/lib icpi.c -lmpi -o cpi_cygwin.exe) 

Regards,
Jayesh

Hi,...

I changed from mpicc to gcc and

BE04845 at NOHW8156 /tmp/mpi/mpich2-1.0.6p1/examples $ make hellow gcc
-I../src/include -I../src/include -O2  -c hellow.c
hellow.c:8:17: mpi.h: No such file or directory
hellow.c: In function `main':
hellow.c:16: error: `MPI_COMM_WORLD' undeclared (first use in this function)
hellow.c:16: error: (Each undeclared identifier is reported only once
hellow.c:16: error: for each function it appears in.)
make: *** [hellow.o] Error 1

*******************************************************************
It seems are not able to find mpi.h
I modify the PATH

********************************************************************
Without succes. I don't know the reason.

I copied the mpi.h from c:\Program Files\MPICH2\include\ to
c:\cygwin\...\src\include\

Result,

BE04845 at NOHW8156 /tmp/mpi/mpich2-1.0.6p1/examples $ make hellow gcc
-I../src/include -I../src/include -O2  -c hellow.c In file included from

make: *** [hellow.o] Error 1


********************************************************************
I copied the mpio.h from c:\Program Files\MPICH2\include\ to
c:\cygwin\...\src\include\


BE04845 at NOHW8156 /tmp/mpi/mpich2-1.0.6p1/examples $ make hellow gcc

make: *** No rule to make target `../lib/libmpich.a', needed by `hellow'.  
Stop.
BE04845 at NOHW8156 /tmp/mpi/mpich2-1.0.6p1/examples

********************************************************************

But libmpich.a doesn't exist in any place

Any idea?

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)

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

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?
