[mpich-discuss] MPI static library link problem.

Wed Jan 4 14:38:05 CST 2017

Hi Anatoly,

I tried you example and cannot reproduce the problem. I saw your compile and link command has many options that are redundant. mpicxx will give the essential options for compile and link with MPICH (see `mpicxx –show`).

Can you try compile and link it with simple options (like the following commands)?

  mpicxx –o mpi_hello_world.o –c mpi_hello_world.cpp
  mpicxx –o mpi_hello_world mpi_hello_world.o

    Hi Yanfei ,

    Test file attached.

    compile command:
    /mpis/Mpich-3.2/mpich-3.2/Ubuntu14.04/bin/mpicxx -c -ftemplate-depth-200 -Wall -Wno-reorder -Wno-comment -Wno-unknown-pragmas -Wno-unused -Wno-non-virtual-dtor -W -fPIC -g -O2 -I/mpis/Mpich-3.2/mpich-3.2/Ubuntu14.04/include -o ./mpi_hello_world.o ./mpi_hello_world.cpp
     -MMD 

    link command:
    /mpis/Mpich-3.2/mpich-3.2/Ubuntu14.04/bin/mpicxx -L/usr/lib/x86_64-linux-gnu/ -L/usr/lib/ -Wl,-rpath=/usr/lib -lcurses -lnsl -lpthread -ldl -lrt -rdynamic -o ./mpi_hello_world ./mpi_hello_world.o -L/usr/lib/x86_64-linux-gnu/ -lpthread

    mpich-3.1
    compile and link pass without any warning or errors.

    mpich-3.2

    * Program pass compile and link.

    * if you will remove comment from line with MPI_Recv, link will fail.

    Please advice,
    Anatoly.

    Hi Anatoly,

    It looks like a linking order problem at the first glance. How did you compile and link using the static library?

        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:

        When I configure MPI with shared libraries:

        my program's build completed correctly.

        When I used MPICH 3.1 I didn't see these problems.
        Can you please advice?

        Regards,
        Anatoly.
