[mvapich-discuss] Failing to compile nemesis and sock channel

[Georg Geiser]

Some channels of MVAPICH2 2.3.2 fail to compile on my system. The 
compiler error message are always like this:

   CC       src/mpi/coll/lib_libmpi_la-allreduce.lo
In file included from src/mpi/coll/allreduce.c:23:
./src/include/coll_shmem.h: In function ‘Cyclic_Rank_list_mapper’:
./src/include/coll_shmem.h:541:28: error: ‘MPIDI_CH3I_CH_comm_t’ {aka 
‘struct <anonymous>’} has no member named ‘rank_list’
      return comm_ptr->dev.ch.rank_list[idx];

Failing builds include ch3:nemesis and ch3:sock, while ch3:mrail builds 
successfully. I could not check ch3:psm due to missing headers.

I use a Debian Buster system with GCC 8.3.0. I specified no additional 
configure flags.
