Comment (by kencu):

 kealib is using c++11 and so when building with gcc, MP adds the ABI flag,
 as it should..

 for that to work, hdf5 would also need the same standard set.

 so now you need to see if **everything** involving hdf5 can be built with
 c++11 (or greater) or not.

 Probably, by this point in time, everything can. So then you set it
 everywhere needed, and things are speaking the same dialect.
