Re: [OMPI users] Compiling C++ program
Hey Brian I tried your command but i guess its not working, there is a warning and then nothing much happens, the command window is shown below [styagi@borelli Mpi]$ mpiCC -o mathbyvec.out mathbyvec.cc -showme pgCC-Warning-Unknown switch: -showme Please help Shekhar Quoting Brian Barrett : > On Apr 16, 2006, at 11:52 AM, Shekhar Tyagi wrote: > > > I am new to MPI and prallel programming, recently i made two > > programs one in C > > and other in C++.

The -showme flag should be supported by all wrapper compilers used by Open MPI, leading me to think that perhaps you're picking up the MPICH wrapper compilers ;).

Re: [OMPI users] Error in configuration for crosscompiler PowerPC
Hi, I downloaded the nightly release version 1.0.3a1r9650 and attempted to configure it disabling the fortran bindings for f77 and f90. However it gives me a new error when checking for epoll_ctlon broken Linux distros: configure:error: cannot run test program while cross compiling. Any inputs will be greatly appreciated. I included the outputs of the configuration as an attachment. Thank you, Jorge On Fri, 14 Apr 2006, Brian Barrett wrote: On Apr 12, 2006, at 7:19 PM, Jorge Parra wrote: I am trying to configure openmpi-1.0.2. However it gives me an error while running the configuration step. It stops when trying to determine the "aligment of bool". I attached the outputs as it is suggested. The system I am using to build openmpi is an intel P4 running RedHat Enterprise 3. I am using it to crosscompile for a system running a power pc 405, and montavista linux 3.1 over it. It appears that this is an issue with our configure tests with more recent versions of GCC and cross-compiling (the error will not occur when not cross compiling). Fixes have been applied for all the upcoming releases. You can grab a nightly release from the 1.0 branch tomorrow and it should work. The nightly tarballs can be downloaded from: http://www.open-mpi.org/nightly/v1.0/ Releases from the 1.0 series will not properly cross-compile the Fortran bindings - they must explicitly be disabled with --disable- mpi-f77 in order for the configure script to complete. ROMIO on the 1.0 series has also not been tested to make sure it properly cross- compiles. This has been fixed for the upcoming 1.1 release, although you will have to run an external program on the target platform in order to generate a seed file for some of the data we need in order to cross-compile our Fortran bindings. We don't have documentation on this just yet, but I can provide you with instructions if you need Fortran bindings. Hope this helps, Brian ompi-output.tar.gz Description: GNU Zip compressed data
