mistake in location of header files

[iman brouwer]

 /usr/include/mpi.h line 1757: #include "ompi/mpi/cxx/mpicxx.h"

It looks inside "/usr/include/" for the "ompi" directory that is not there. The file it is looking for is inside "/usr/include/openmpi"
So when you try to compile a c++ file including mpi.h it ends up with a "no such file..." error.

P.S. I solved the problem for me with a symbolic links.

What version of openmpi are you using ?
could you include the output of

dpkg -l | grep openmpi

thanks,

    Koen

Hoi Koen,

Here's the output:

~ $dpkg -l | grep openmpi
ii openmpi-bin 1.1-2.5
high performance message passing library
ii openmpi-common 1.1-2.5
high performance message passing library
ii openmpi-dbg 1.1-2.5
high performance message passing library
ii openmpi-dev 1.1-2.5
high performance message passing library
ii openmpi-libs0 1.1-2.5
high performance message passing library

Could you try to install 1.1-2.5ubuntu1 as 1.1-2.5 has some issues with incorrect directories

to do this you'll can activate the updates repository in the software sources : System->Administration->Software Sources->Updates->activate gutsy-updates

[iman brouwer (iman-brouwer)]

Hi Koen,

I've updated to the new version:
ii openmpi-bin 1.1-2.5ubuntu1
high performance message passing library
ii openmpi-common 1.1-2.5ubuntu1
high performance message passing library
ii openmpi-dbg 1.1-2.5ubuntu1
high performance message passing library
ii openmpi-dev 1.1-2.5ubuntu1
high performance message passing library
ii openmpi-libs0 1.1-2.5ubuntu1
high performance message passing library

But it is still giving me the following error:
In file included from /home/brouwer/qform/iman/mpi_test/src/main.cpp:4:
/usr/include/mpi.h:1757:33: error: ompi/mpi/cxx/mpicxx.h: No such file or
directory

In '/usr/include/openmpi/', the following symbolic link used to solve the
problem for me: cxx -> ompi/mpi/cxx

Iman

P.S. I'm on a kubuntu system.

Hi iman,

  could you include a example cpp source file that causes the issue and how to reproduce the error ?

    thanks,

       Koen

[iman brouwer (iman-brouwer)]

Hi Koen,

This simple executable produces the error below:
 --------------------------

#include <mpi.h>

 int main(int argc, char *argv[])
 {
   MPI_Status stat;
   MPI_Init(&argc,&argv);
   MPI_Finalize();
   return 0;
 }

-----------------------------
Error when building the executable:

In file included from /home/iman/code/mpitest/src/main.cpp:1:
/usr/include/mpi.h:1757:33: error: ompi/mpi/cxx/mpicxx.h: No such file or
directory

Hope that helps,

Iman

Hi Iman,

   I tried the following on a gutsy amd64 with

ii openmpi-bin 1.1-2.5ubuntu1 high performance message passing library
ii openmpi-common 1.1-2.5ubuntu1 high performance message passing library
ii openmpi-dev 1.1-2.5ubuntu1 high performance message passing library
ii openmpi-libs0 1.1-2.5ubuntu1 high performance message passing library

   mpic++ main.cpp

this produced an a.out executable without any error messages on my system

I do have
/*
 * Conditional MPI 2 C++ bindings support. Include if:
 * - The user does not explicitly request us to skip it (when a C++ compiler
 * is used to compile C code).
 * - We want C++ bindings support
 * - We are not building OMPI itself
 * - We are using a C++ compiler
 */
#if !defined(OMPI_SKIP_MPICXX) && OMPI_WANT_CXX_BINDINGS && !OMPI_BUILDING
#if defined(__cplusplus) || defined(c_plusplus)
#include "ompi/mpi/cxx/mpicxx.h"
#endif
#endif

at the end of /usr/include/mpi.h

but this include does not seem to be included when I use mpic++

I have the same problem running Version: 1.1-2.5.
The following command fixed it:
cd /usr/include/
sudo ln -s openmpi/ompi ompi

I'm using normal ubuntu.

ilmar

[ilmarw (ilmar-wilbers)]

I'm using 1.1-2.5ubuntu1.

[ilmarw (ilmar-wilbers)]

After fixing some other problem with openmpi, see my posts of today at https://bugs.launchpad.net/ubuntu/+source/openmpi/+bug/152273, things seem to be working now.

ilmar

[ilmarw (ilmar-wilbers)]

This is a bug, it happens when a normal c++ compiler is used instead of mpicxx. Seems to be fixed in Hardy.

ilmar

[iman brouwer (iman-brouwer)]

Switched to Hardy, and it works perfectly now.

In Gutsy I had the problem with CMake even with the mpic++ compiler
specified, e.g.
SET( CMAKE_CXX_COMPILER "mpic++" )

In Hardy the problem is solved.

Thanks guys!

Iman

P.S. Sorry for the late response, I had some serious computer issues and
was away for a week.
