week 46.2016 mpi comlie error: unrecognized command line option “-std=c++11”

[Anonymous]

Hi, 

I am trying to compile weekly build 46.2016 using “./scons.py bin -j3 mode=release extras=mpi”  and get this error:

error: unrecognized command line option “-std=c++11”

My gcc and g++ version is 4.8.2 20140120 (Red Hat 4.8.2-15). Any idea why this is happening? Any suggestion is highly appreciated.

 

Thanks!

While your g++ version may be 4.8.2, the version of your mpi compiler that you’re using probably isn’t. What does `mpicc –version`, `mpiCC –version` and `mpicxx –version` show?

If they give the appropriate version (4., then try copying main/source/tools/build/site.settings.killdevil to main/source/tools/build/site.settings.

If they give you a version number that’s pre-4.8, then you need to talk to your sysadmin to see if you have a version of the mpi compiler which has C++11 support.  If one is installed, then you either need to adjust your paths such that’s the one that’s found with the `mpicc –version` (and adjust site.settings as above), or you need to explicitly list which compilers you want to use in main/source/tools/build/user.settings.   — See main/source/tools/build/site.settings.csbmpi for an example of how to do it.

Thanks very much! Replacing the site.settings with the killdevil did the trick.
