[mpich-discuss] need to compile unix code as windows exe

[Jayesh Krishna]

Hi,
	Please find my comments below,
 
>> ...the file "libmpi.a" and "libfmpich2g.a" in "C:\Program
Files\MPICH2\lib" are 0kb files ...
 The gcc libs should not be 0kb in size. There is something wrong with
your installation of MPICH2. I recommend that you uninstall your current
version of MPICH2, reboot your machine (so that you don't have any MPI
programs running in the bg), install the latest stable version (1.0.8) of
MPICH2.

Unable to connect to mhelallpt-xp ...
 You have not registered your username/password correctly with mpiexec.
You should run "mpiexec -register" and register your username/password
(Run "mpiexec -validate" to make sure that the registered
username/password works)

Regards,
Jayesh

Hello

Thank you for your help, but I still need help to get my program running
on a windows cluster please. I followed both approaches as mentioned
before,

The first is trying to configure mpich2-1.0.8 to use mpicc on cygwin,
gives the following errors on cygwin on Windows XP 2002 with SP 3
*****************************************
$ ./configure
./configure: line 12: $'\r': command not found
./configure: line 23: syntax error near unexpected token `$'in\r''
'/configure: line 23: `  case `(set -o) 2>/dev/null` in
*****************************************

the second is using the cygwin gcc and linking with lmpich, and that's how
it goes:

some information that might help:
the file "libmpi.a" and "libfmpich2g.a" in "C:\Program Files\MPICH2\lib"
are 0kb files, I have "libmpichd.a" as a 1061 Kb file in the same folder,
and "libmpich.a" as 1058 KB, and 'libmpicxx.a" as 199 kb file, "mpi.lib"
is a 126 kb file, and "fmpich2.lib" as 130 kb file.

the gcc version is
*****************************************
$ gcc -v
Reading specs from /usr/lib/gcc/i686-pc-cygwin/3.4.4/specs
Configured with:
/usr/build/package/orig/test.respin/gcc-3.4.4-3/configure --ver bose

--enable-libstdcxx-debug Thread model: posix gcc version 3.4.4 (cygming
special, gdc 0.12, using dmd 0.125)
*****************************************

compiling a simple program like :
*****************************************
#include <stdio.h>
#include <math.h>
#include <mpi.h>

int main(int argc, char **argv) {
    int myProcid, ClusterSize;
    MPI_Init(&argc, &argv);
    MPI_Comm_rank(MPI_COMM_WORLD, &myProcid);
    MPI_Comm_size(MPI_COMM_WORLD, &ClusterSize);
    printf ("Hello World Process %d / %d.\n", myProcid, ClusterSize);
    //printf ("the ceill(10.55) = %lld\n" , ceill(10.55));
    getc (stdin);
    MPI_Finalize();
    return 0;
}
*****************************************
It is compiled as:
*****************************************
$ gcc hello.c -I "/cygdrive/f/Program Files/MPICH2/include" -L
"/cygdrive/f/Program Files/MPICH2/lib" -lmpich -lm -o hello.exe

creates the exe file with no errors, however, when I try to execute it
using the mpich2 for windows "wmpiexec" Interface with 4 processes all on
the current node and showing different windows, the windows don't come up,
command shown is:
*****************************************
"C:\Program Files\MPICH2\bin\mpiexec.exe" -n 4  -noprompt
"C:\cygwin\home\user\hello.exe"
*****************************************

copying the same command to cygwin, I get the errors shown:
*****************************************
$ "/cygdrive/f/Program Files/MPICH2/bin/mpiexec.exe" -n 4  -noprompt
hello.exe Credentials for Manal rejected connecting to mhelallpt-xp
Aborting: Unable to connect to mhelallpt-xp
*****************************************


However, compiling my mpi program using the following command in a make
file:
*****************************************
$gcc "/cygdrive/f/Program Files/MPICH2/include" -L "/cygdrive/f/Program
Files/MPICH2/lib" -lmpich -lm  main.c

where the main.o is:
main.o :  main.c main.h utils.h globals.h
    gcc -g -I "/cygdrive/f/Program Files/MPICH2/include" -L
"/cygdrive/f/Program Files/MPICH2/lib" main.c -lmpich -o main.o
*****************************************


I get the following errors:
*****************************************
/home/user/proj/main.c:112: undefined reference to `_MPI_Barrier'
/home/user/proj/main.c:174: undefined reference to `_MPI_Wtime'
/home/user/proj/main.c:242: undefined reference to `_MPI_Send'
/home/user/proj/main.c:251: undefined reference to `_MPI_Recv'
/home/user/proj/main.c:314: undefined reference to `_MPI_Init'
/home/user/proj/main.c:316: undefined reference to `_MPI_Comm_rank'
/home/user/proj/main.c:318: undefined reference to `_MPI_Comm_size'

/home/user/proj/main.c:3379: undefined reference to `_MPI_Isend'
/home/user/proj/main.c:3514: undefined reference to `_MPI_Iprobe'
/home/user/proj/main.c:3520: undefined reference to `_MPI_Recv'
*****************************************

It is basically all MPI calls I make, and what I couldn't understand, why
the "MPI_Init" "MPI_Comm_rank", "MPI_Comm_size" and "MPI_Finalize"
was found on the test program, and not found in the main program.

when I compile using the above command without the make file, I get more
errors like:

*****************************************
main.c:165: error: `MPI_Status' undeclared (first use in this function)
main.c:242: error: `MPI_INT' undeclared (first use in this function)
main.c:302: error: `MPI_Group' undeclared (first use in this function)
main.c:316: error: `MPI_COMM_WORLD' undeclared (first use in this
function)
main.c:3432: error: `MPI_LONG' undeclared (first use in this function)
main.c:3435: error: `MPI_LONG_LONG' undeclared (first use in this
function)
main.c:3485: error: `MPI_Status' undeclared (first use in this function)
main.c:3514: error: `MPI_ANY_SOURCE' undeclared (first use in this

main.c:3221: error: `MPI_ERR_TAG' undeclared (first use in this function)
main.c:3225: error: `MPI_ERR_RANK' undeclared (first use in this function)
*****************************************

I also  get simillar errors to all long long functions which are not found
on cygwin when I searched or used the "man" command like the
following:

*****************************************
/home/user/proj/main.c:907: undefined reference to `_sqrtl'
/home/user/proj/main.c:1743: undefined reference to `_powl'
/home/user/proj/main.c:2006: undefined reference to `_ceill'
/home/user/proj/main.c:2035: undefined reference to `_floorl'
*****************************************
I appreciate your help a lot,

Kind Regards,

Manal
