Gilles, Thanks for the clarification. I did notice the option in the configure script. I appreciate the information on the third party C++ bindings. The library I'm using is VTK and they happen to still rely on C++ bindings for their parallel I/O module (unless I'm mistaken here, but this seems

Re: [OMPI users] libmpi_cxx.so doesn't exist in lib path when installing 3.0.1

Ajith, Note the C++ bindings have not been removed yet from Open MPI. You need to configure --enable-mpi-cxx in order to build them (this is no more the default option) As Nathan pointed out, the C++ bindings will likely be removed from Open MPI 4, so you will have to modernize your code

Re: [OMPI users] libmpi_cxx.so doesn't exist in lib path when installing 3.0.1

Thanks for the quick reply. One of the third-party packages we're using still depends on the C++ bindings, but I'll look to migrating them to the C bindings. Ajith On Sat, Apr 7, 2018 at 4:40 PM, Nathan Hjelm wrote: > The MPI C++ bindings were depricated more than 10 years ago

The MPI C++ bindings were depricated more than 10 years ago and were removed from the standard 6 years ago. They have been disabled by default for a couple of years in Open MPI. They will likely be removed in Open MPI 4.0. You should migrate your code to use the C bindings. -Nathan > On Apr
