[Mvapich-discuss] GCC-11.1.0 Support?

[Clark, Nicholas - 1002 - MITLL]

When compiling mvapich-2.3.5 with GCC-11.1.0 on CentOS 7.9 I am seeing  the
following error when compiling with these flags:

./configure --prefix=/opt/mvapich2-2.3.5 --with-device=ch3:nemesis:tcp
--disable-fortran

make

.

make[2]: Entering directory `/root/mvapich2-2.3.5'

  CC       src/mpi/attr/lib_libmpi_la-attr_delete.lo

In file included from src/mpi/attr/attr_delete.c:8:

./src/include/mpiimpl.h:1632:1: error: size of array element is not a
multiple of its alignment

1632 | extern MPID_Request MPID_Request_direct[];

      | ^~~~~~

./src/include/mpiimpl.h:1632:1: error: size of array element is not a
multiple of its alignment

make[2]: *** [src/mpi/attr/lib_libmpi_la-attr_delete.lo] Error 1

make[2]: Leaving directory `/root/mvapich2-2.3.5'

make[1]: *** [all-recursive] Error 1

make[1]: Leaving directory `/root/mvapich2-2.3.5'

make: *** [all] Error 2

.

 

Is this an issue of changes in GCC-11.1.0?

 

I am able to compile with GCC-10.3.0.

 

Sincerely,
