Re: [OMPI users] MPI 2 support in sm btl
Thanks for your answers. Is there a similar issue with mx BTL? I mean, using the mx BTL, is it possible to reach a parent job from a spawned process?

Re: [OMPI users] OBJ_CLASS_INSTANCE error: initializer element is not constant - Windows 7 64 bit mingw-w64 4.6.3
Hi Roger, To be honest, this MinGW support for Open MPI was integrated when the 64 bit MinGW wasn't available, so I haven't tested it for the 64 bit build. I'll give a try, and come back to you soon. Thanks for your report. Regards, Shiqing On 2011-12-22 4:54 PM, Roger Martin wrote: Hi, Working on building on windows with MinGW.

Re: [OMPI users] OBJ_CLASS_INSTANCE error: initializer element is not constant - Windows 7 64 bit mingw-w64 4.6.3
Hi Shiqing, I was able to build the open-rte and the rest by applying g++.exe instead of gcc.exe. I couldn't find any combination of --std=C9x to make the c compiling happy for gcc.exe. For open-rte build I ran into issues with opal_ifisloopback impl unreferenced. I'll regenerate my steps and post more discrete pieces.
