Re: [OMPI users] OBJ_CLASS_INSTANCE error: initializer element is not constant - Windows 7 64 bit mingw-w64 4.6.3

[Shiqing Fan]

Hi Roger,

Have you tested also with 32 bit build?

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.

Actually, the C9x option is not really necessary here, but "-x c" should 
do the work.  It is defined in the CMake variable OMPI_C_LAN_FLAG, is it 
also empty in your CMakeCache file?


For open-rte build I ran into issues with opal_ifisloopback impl 
unreferenced.  I'll regenerate my steps and post more discrete pieces.

It would be great if you can provide your CMake Config settings and 
log/cache file. Thanks a lot.

Regards,
Shiqing




Regards,
Roger

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

Hi,

Working on building on windows with MinGW.  Have built libopen-pal, 
opal-restart, opal-wrapper and am at the open-rte stage of the build.
The  OBJ_CLASS_INSTANCE hits errors about 'initializer element is 
not constant'. Open-pal also uses OBJ_CLASS_INSTANCE and doesn't 
throw this error.
Tried g++ instead of gcc and source such as rmcast_base_open.c 
compiled successfully but then I get into name mangling issues.

Being not familiar with the code I haven't yet determined why 
open-pal is successful and open-rte isn't.  Flag difference?  Is 
there code difference between them in how they apply the 
OBJ_CLASS_INSTANCE?

$ ../../mingw64/bin/gcc.exe --version
gcc.exe (GCC) 4.6.3 20111105 (prerelease)
