Dear MPICH, I use MPICH 3.2 configured (without shared libraries): ./configure --prefix=/mpis/Mpich-3.2/mpich-3.2/Ubuntu14.04 --enable-error-checking=runtime --enable-g=dbg CFLAGS=-fPIC CXXFLAGS=-fPIC FFLAGS=-fpic --enable-threads=runtime --enable-totalview *--enable-shared=no* --disable-fortran When I try to compile my program I get linkage errors: /mpis/Mpich-3.2/mpich-3.2/Ubuntu14.04/lib/libmpicxx.a(initcxx.o): In function `MPI::File::Create_errhandler(void (*)(MPI::File&, int*, ...))': /mpis/Mpich-3.2/mpich_3.2_config/mpich-3.2/src/binding/cxx/initcxx.cxx:693: undefined reference to `MPIR_Errhandler_set_cxx' /mpis/Mpich-3.2/mpich-3.2/Ubuntu14.04/lib/libmpicxx.a(initcxx.o): In function `MPI::Comm::Create_errhandler(void (*)(MPI::Comm&, int*, ...))': /mpis/Mpich-3.2/mpich_3.2_config/mpich-3.2/src/binding/cxx/initcxx.cxx:704: undefined reference to `MPIR_Errhandler_set_cxx' /mpis/Mpich-3.2/mpich-3.2/Ubuntu14.04/lib/libmpicxx.a(initcxx.o): In function `MPI::Win::Create_errhandler(void (*)(MPI::Win&, int*, ...))': /mpis/Mpich-3.2/mpich_3.2_config/mpich-3.2/src/binding/cxx/initcxx.cxx:714: undefined reference to `MPIR_Errhandler_set_cxx' /mpis/Mpich-3.2/mpich-3.2/Ubuntu14.04/lib/libmpicxx.a(initcxx.o): In function `MPI::Comm::Create_keyval(int (*)(MPI::Comm const&, int, void*, void*, void*, bool&), int (*)(MPI::Comm&, int, void*, void*), void*)': /mpis/Mpich-3.2/mpich_3.2_config/mpich-3.2/src/binding/cxx/initcxx.cxx:510: undefined reference to `MPIR_Keyval_set_proxy' /mpis/Mpich-3.2/mpich-3.2/Ubuntu14.04/lib/libmpicxx.a(initcxx.o): In function `MPI::Datatype::Create_keyval(int (*)(MPI::Datatype const&, int, void*, void*, void*, bool&), int (*)(MPI::Datatype&, int, void*, void*), void*)': /mpis/Mpich-3.2/mpich_3.2_config/mpich-3.2/src/binding/cxx/initcxx.cxx:574: undefined reference to `MPIR_Keyval_set_proxy' /mpis/Mpich-3.2/mpich-3.2/Ubuntu14.04/lib/libmpicxx.a(initcxx.o): In function `MPI::Win::Create_keyval(int (*)(MPI::Win const&, int, void*, void*, void*, bool&), int (*)(MPI::Win&, int, void*, void*), void*)': /mpis/Mpich-3.2/mpich_3.2_config/mpich-3.2/src/binding/cxx/initcxx.cxx:638: undefined reference to `MPIR_Keyval_set_proxy' /mpis/Mpich-3.2/mpich-3.2/Ubuntu14.04/lib/libmpicxx.a(initcxx.o): In function `MPI::Op::Init(void (*)(void const*, void*, int, MPI::Datatype const&), bool)': /mpis/Mpich-3.2/mpich_3.2_config/mpich-3.2/src/binding/cxx/initcxx.cxx:393: undefined reference to `MPIR_Op_set_cxx' /mpis/Mpich-3.2/mpich-3.2/Ubuntu14.04/lib/libmpicxx.a(initcxx.o): In function `MPI::Comm::Reduce_scatter_block(void const*, void*, int, MPI::Datatype const&, MPI::Op const&) const': /mpis/Mpich-3.2/mpich_3.2_config/mpich-3.2/./src/binding/cxx/mpicxx.h:1490: undefined reference to `MPI_Reduce_scatter_block' collect2: error: ld returned 1 exit status When I configure MPI with shared libraries: ./configure --prefix=/mpis/Mpich-3.2/mpich-3.2/Ubuntu14.04 --enable-error-checking=runtime --enable-g=dbg CFLAGS=-fPIC CXXFLAGS=-fPIC FFLAGS=-fpic --enable-threads=runtime --enable-totalview --disable-fortran my program's build completed correctly. When I used MPICH 3.1 I didn't see these problems. Can you please advice?
