Hi,

I would suggest build a 64-bit libxml2 instead of using ‘-m64’ for MPICH.

The library is available. tyr mpich-3.1.1 431 file /usr/lib/sparcv9/libxml2.so /usr/lib/sparcv9/libxml2.so: ELF 64-bit MSB dynamic lib SPARCV9 Version 1, dynamically linked, not stripped, no debugging information available I get also an error if I try to build a 32-bit version with gcc-4.9.0. ../mpich-3.1.1/configure --prefix=/usr/local/mpich-3.1.1_32_gcc \ CC="gcc" CXX="g++" F77="gfortran" FC="gfortran" \ CFLAGS="" CXXFLAGS="" FFLAGS="" FCFLAGS="" \ LDFLAGS="-L/usr/lib -Wl,-rpath /usr/lib -lxml2" \ --enable-f77 --enable-fc --enable-cxx --enable-romio \ --enable-debuginfo --enable-smpcoll \ --enable-threads=runtime --with-thread-package=posix \ --enable-shared \ |& tee log.configure.$SYSTEM_ENV.$MACHINE_ENV.32_gcc tyr mpich-3.1.1-SunOS.sparc.32_gcc 419 tail -25 log.make.SunOS.sparc.32_gcc CC src/binding/fortran/mpif_h/lib_libmpifort_la-statusc2f.lo CC src/binding/fortran/use_mpi/lib_libmpifort_la-typef90cmplxf.lo CC src/binding/fortran/use_mpi/lib_libmpifort_la-typef90realf.lo CC src/binding/fortran/use_mpi/lib_libmpifort_la-typef90intf.lo rm -f src/binding/fortran/use_mpi/mpifnoext.h sed -e 's/^C/\!/g' -e '/EXTERNAL/d' \ -e '/REAL\*8/d' \ -e '/DOUBLE PRECISION/d' \ -e '/MPI_WTICK/d' src/binding/fortran/mpif_h/mpif.h > src/binding/fortran/use_mpi/mpifnoext.h MOD src/binding/fortran/use_mpi/mpi_constants.mod-stamp MOD src/binding/fortran/use_mpi/mpi_sizeofs.mod-stamp MOD src/binding/fortran/use_mpi/mpi_base.mod-stamp MOD src/binding/fortran/use_mpi/mpi.mod-stamp GEN lib/libmpifort.la ld: warning: file /export2/prog/SunOS_sparc/gcc-4.9.0/bin/../lib/gcc/sparc-sun-solaris2.10/4.9.0/../../../libgfortran.so: linked to /usr/local/gcc-4.9.0/lib/libgfortran.so: attempted multiple inclusion of file CXX src/binding/cxx/initcxx.lo CXXLD lib/libmpicxx.la ld: fatal: file libmpicxx.so.12: open failed: No such file or directory ld: fatal: file processing errors.

Solaris uses LD_LIBRARY_PATH for 32-bit libraries/executables and LD_LIBRARY_PATH_64 for 64-bit ones. When I build "mpich" as 64-bit version, the 32-bit library for "libxml2.so" will be used without rpath. I don't know if that is a problem of our gcc-installation or your Makefile, but I could solve the problem with rpath.
