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 _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
