Subject: Re: [OMPI devel] Fwd: Re: [Score-P support] Compile errors of Fedora rawhide

Can't do much about 1.7.4, but fwiw 1.7.5 will not have this problem - nor will it be present in 1.8.0 - as we have fully converted to MPI-3 now (and the version will reflect it).

But openmpi 1.7.4 is still MPI_VERSION 2 (SUB 2). If I change scorep to add the const qualifiers for openmpi 1.7.4, then it has trouble with some different routines that are missing the const qualifiers, for example MPI_Address and MPI_Info_set. It's tough to support a mix like this.

> I can reproduce the results with openmpi 1.7.4. It seems that openmpi 1.7.4 added const qualifiers to some MPI function parameters which cause this error. For MPI 3 many function arguments get such a const qualifier, and openmpi 1.7.4 added some MPI 3 features. However, not all function signatures in openmpi 1.7.4 are changed to the MPI 3 standard. Thus, there is a mixture of MPI 2 compliant functions and MPI 3 compliant functions. To support such mixtures we need to add a couple of additional checks. If you want to use the current Score-P with openmpi 1.7.4, the easiest workaround you could try is to build Score-P with the mpi.h header from openmpi 1.7.3. However there is no guarantee that it works. Another option is to adapt the Score-P MPI function wrapper signatures to the openmpi 1.7.4.
