Hi Mike, Could you please try a newer release (e.g., mpich-3.3b3) ? This looks like a cherry-picking mistake when we made the 3.2.1 release. The alignment fix commit (c3bb71e) was made after the commit that introduces MPIR_Memcpy, but only the alignment commit was picked into 3.2.1.

Hi, I did some more digging at it appears the call to the unresolved function MPIR_Memcpy was introduced in 2016 by Changeset https://trac.mpich.org/projects/mpich/changeset/c3bb71e72f88034ce7ebcc681445....

Can anyone confirm they have built MPICH 3.2.1 on SPARC with Sun Studio, and if so, if/how they resolved the call to MPIR_Memcpy that appears in src/mpid/ch3/channels/nemesis/src/ch3_progress.c?

Thanks for any help. --Mike

Hi, I'm having trouble building MPICH 3.2.1 and I'm hoping for some help resolving the problem(s). Perhaps someone has seen this before.

The environment is: % uname -a SunOS spc64sol113ci 5.11 11.3 sun4v sparc sun4v % f95 -V f90: Studio 12.5 Fortran 95 8.8 SunOS_sparc 2016/05/31

The config command I used is: % ./configure --prefix=/export/home4/erhome/jenkins/michaelp/ports/fnl/sol113/mpi/build_area/Mikes_build CC=cc CXX=CC F77=f77 FC=f95 CFLAGS=-m64 CXXFLAGS=-m64 FFLAGS=-m64 FCFLAGS=-m64 LDFLAGS=-m64

Looking at the output from running mpich-3.2.1/make, it appears the problem is an unresolved symbol MPIR_Memcpy: CCLD src/env/mpichversion Undefined first referenced symbol in file MPIR_Memcpy lib/.libs/libmpi.a(lib_libmpi_la-ch3_progress.o) ld: fatal: symbol referencing errors *** Error code 2 The following command caused the error: echo " CCLD " src/env/mpichversion;/bin/sh ./libtool --silent --tag=CC --mode=link cc -m64 -O2 -static -m64 -o src/env/mpichversion src/env/mpichversion.o lib/libmpi.la -lnsl -lsocket -lpthread make: Fatal error: Command failed for target `src/env/mpichversion'

I can provide the full output from my config and make commands if that helps, but I didn't want to overload my first email to this mail group.

Thanks for any help you are able to provide, --Mike
