I faced a warning "declaration âstruct MPI::Grequest_intercept_tâ does
not declare anything" using openmpi 1.2.4 (compiling under Fedora 10
with mpic++ wrapper over gcc 4.3.2) and don't know how to solve it.
Browsing the Internet i've found an advise just to ignore it, but i
don't think it is impossible to solve it in another way.
I have a correct working single thread program. Then i just include
mpi.h, compile and get this:
In file included
/usr/include/openmpi/1.2.4-gcc/openmpi/ompi/mpi/cxx/request_inln.h:347: warning: declaration âstruct MPI::Grequest_intercept_tâ does not declare anything
The program is still works correctly but this warning makes me nervous.
Sincerely yours, Alexey.
