[mpich-discuss] question regarding compiling/linking under MingW (MPICH2 1.08)

[ting lei]

Hi, 

Sorry to bother all. I have some questions regarding using MPICH2 1.08 with MingW

I tried compile MPICH2 1.08 on two different machines, and have met different problems. I was wondering if someone with a lot experience could help me out here. thanks in advance.

1) The most successful attempt was on a win32 platform, XPSP3 with MingW+gcc3.4.5
The command line I used was:
gcc -I /c/MPICH2/include/ -lmpi -L/c/MPICH2/lib/ test.c 
and I get the following error:
C:/DOCUME~1/ting/LOCALS~1/Temp/cc40AD3K.o:test.c:(.text+0x38): undefined reference to `MPI_Init'
C:/DOCUME~1/ting/LOCALS~1/Temp/cc40AD3K.o:test.c:(.text+0x4b): undefined reference to `MPI_Comm_rank'
collect2: ld returned 1 exit status

It seems that the library file libmpi.a is corrected specified, because if I change it to -lmpi1 it will report 
c:\mingw\bin\..\lib\gcc\mingw32\3.4.5\..\..\..\..\mingw32\bin\ld.exe: cannot find -lmpi1
collect2: ld returned 1 exit status


2) My less successful attempt was on a Win64 (Vista64) platform with MingW + gcc4.3:
I tried installing the mpich2-1.0.8-win-x86-64.msi. but 
a) after the installation, I couldn't find libmpi.a in MPICH2\lib folder as I was able to in case 1).
b) when I am compiling the toy test program, I get many errors like this:


In file included from test.c:1:
c:/MPICH2/include/mpi.h:334: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'MPI_Aint'

Is this a gcc4.x problem?


Best

Hi,
 You could try installing MPICH2 on windows (from 
the installer available at http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads) 
and compile your code and link with the gcc libs (*.a) provided with the 
installation (MPICH2\lib directory).
 
Regards,
Jayesh

Hi,

This might be a newbie question.
I see in this thread that people can compile MPICH2 with MingW. I tried that with MingW (gcc 4.3 and 3.4x) several times but 
I was never able to get past the ./configure step. 
"I have compiled a C executable using the MPICH2 Windows libraries and MinGW."
Could someone please give me some pointers how to compile such an executable?
More specifically, do I have to compile MPICH2 itself from source using MinGW then use some program such as mpicc?? 
or should I just compile a regular c program and run it with mpiexec.exe ?
If I were to compile MPICH2 itself with MingW, what other packages do I need except the latest version of MingW?


Many thanks for your help
