A++ & P++

Prerequisites

P++ requires MPI. We have had success using OpenMPI-1.4.4 MPICH-1.2.7.

Build Instructions

  1. Download tarball of source code: AppPpp-08-28-2007.tar.gz and unpack to $INSTALL_DIR/src/a+p+ 
    cd $INSTALL_DIR/src/
wget http://download.hao.ucar.edu/pub/schmitt/cism/LTR-para/a++p++-08-28-2007.tar.gz
tar -zxvf a++p++-08-28-2007.tar.gz
    1. (warning) Developers who want the latest & greatest (and quite possibly the most broken version of code) may download from the CISM repository
      Note: This requires an Subversion account 
      cd $INSTALL_DIR/src
svn --username [yourname] co https://proxy.subversion.ucar.edu/cism_CSE/trunk/a++p++
  2. Prepare the A++ & P++ build using a configure script. (Note: you will run configure three seperate times during this process) 
    cd $INSTALL_DIR/src/a++p++
./configure --prefix=$INSTALL_DIR --enable-PXX --no-recursion
  3. Configure, build and install A++ 
    cd $INSTALL_DIR/src/a++p++/A++
 ./configure --prefix=$INSTALL_DIR --with-CC=$CC --with-CXX=$CXX
 make
 make install
  4. Configure, build and install P++ 
    1. cd $INSTALL_DIR/src/a++p++/P++
 ./configure --prefix=$INSTALL_DIR --enable-PXX --with-CC=$MPICC --with-CXX=$MPICXX --disable-mpirun-check --with-mpi-libs=" "
 make
 make install
  5. Ensure that the build for both A++ and P++ went okay: 
    cd $INSTALL_DIR/src/a++p++
 make check
    This will traverse source directories, verifying the build went okay. All tests must pass in order to build LFM-para.
  6. Set a few soft links for the installed files: 
    ln -s $INSTALL_DIR/A++/install/include $INSTALL_DIR/A++/include
ln -s $INSTALL_DIR/A++/install/lib $INSTALL_DIR/A++/lib
ln -s $INSTALL_DIR/P++/install/include $INSTALL_DIR/P++/include
ln -s $INSTALL_DIR/P++/install/lib $INSTALL_DIR/P++/lib
  7. You are now ready to install the next prerequisite, PVM.

Troubleshooting

  • On an IBM AIX system, you must pass the following flag to the A+/P+ configure scripts: 
    --host=powerpc-ibm-aix5
  • If you are getting weird build errors, try using gmake instead of make.
  •  On an AIX system like BlueVista, you may get an error, such as $INSTALL_DIR/src/a+p+/config/mklib.aix: 0403-006 Execute permission denied.. This probably happened because you forgot to add the flag --host=powerpc-ibm-aix5 to configure. Otherwise, you can try to manually set the permissions on this file to executable. 
    chmod gu+x $INSTALL_DIR/src/a++p++/config/mklib.aix
  • When installing, you may get the error cannot stat libApp.so': A file or directory in the path name does not exist. You must build A+P+ with shared libraries turned OFF.
  • When building P++, you may get an error like: 
    catastrophic error:
#error directive: "SEEK_SET is #defined but must not be for the C\+\+ binding of MPI"
error "SEEK_SET is #defined but must not be for the C\+\+ binding of MPI"
    Solution: add -DMPICH_IGNORE_CXX_SEEK and -DMPICH_SKIP_MPICXX to the CPPFLAGS environment variable. If you're using BASH: 
    export CPPFLAGS="-DMPICH_IGNORE_CXX_SEEK -DMPICH_SKIP_MPICXX"
    If you're using csh: 
    setenv CPPFLAGS "-DMPICH_IGNORE_CXX_SEEK -DMPICH_SKIP_MPICXX"
    Once this variable is set clean up and re-configure your build 
    gmake clean
 ./configure [configure-options from above|configure-options from above]
 gmake
  • When building A++ with the Portland Group compilers, you may get an error like: 
    pgcc-Error-Unknown switch: -Wstrict-prototypes
    Solution: remove any references to -Wstrict-prototypes from the Makefile.
  • When building P++ with the Portland Group Compilers, you may get the linker errors: 
    int_MDI_5.c:-( .text+0x5c1): undefined reference to }}__mth_i_dpowdx'
 int_MDI_5.c:-( .text+0x909): undefined reference to {{__mth_i_dpowdx'
 int_MDI_5.c:-( .text+0x10f3): undefined reference to }}__mth_i_dpowdx'
 int_MDI_5.c:-( .text+0x1969): undefined reference to {{__mth_i_dpowdx'
 int_MDI_5.c:-( .text+0x267c): undefined reference to }}__mth_i_dpowdx'
    The problem is that your missing the PGI SSE math libraries -lpgsse1 -lpgsse2 from your link line. While you can add these with to various compilers (i.e. gcc), make sure that you are using the Portland compilers to build the code. You might want to set the LDFLAGS environment variable to point to these and re-configure the library from scratch: 
    export LDFLAGS="-lpgsse1 -lpgsse2"
  • When building P++, you get the error: 
    CC           -o test2000_01  test2000_01.o  -L../src -lPpp -lPpp_static -lPpp      -lc  -lm

    Solution: Recompile without linking libc (ie. remove "-lc" from build command)
