Mac上PETSc安装问题

#Mac上PETSc安装问题

##安装流程

1. Download and install MPICH.

2. Download and unzip/untar the PETSc package to /usr/local/petsc/ (or wherever you want to put PETSc). Unzip/untar the download from /usr/local/petsc/ as follows:

   sudo gunzip -c petsc.tar.gz | sudo tar -xof -

3. Set the PETSC_DIR and PETSC_ARCH environmental variables. This can be done by adding the following lines to ~/.bash_profile

   set environmental variables for PETSc

   export PETSC_DIR=/usr/local/petsc/petsc-x.xx.x/

   export PETSC_ARCH=arch-darwin-c-opt

   Don’t forget to source ~/.bash_profile after making the change.

4. From within the PETSc directory, run the configure script with flags to use gcc, g++, f77, and the BLAS and LAPACK libraries included in Apple’s vecLib:

   sudo python ./config/configure.py --with-blas-lapack-lib="-framework accelerate" --with-mpi-dir=/usr/local/opt/mpich

5. Build with the debug C++/gfortran target and run the test script:

   sudo make BOPT=g_c++sudo make BOPT=g_c++ test

6. Build and test with whatever other targets you want, e.g. the optimized C++/gfortran target BOPT=O_c++, the debug C/gfortran target BOPT=g, or the optimized C/gfortran target BOPT=O.

注意事项

blas和lapack库包含在OS X的Accelerate Framework中，所以无需另外安装blas和lapack库。

##pyhyp安装

这样安装貌似pyhyp用不了，没有petscvec.h90文件，只有petscvec.h文件。重新按照pyhyp的方法安装试试。

sudo ./configure --with-shared-libraries --download-superlu_dist=yes --download-parmetis=yes --download-metis=yes --with-fortran-interfaces=1 --with-debuggig=no --with-scalar-type=real --with-cxx-dialect=C++11 --PETSC_ARCH=real-opt

Mac上最简单的安装方法是直接brew install petsc。

PETSc v3.8以后，不再需要在fortran文件中include任何.h90文件了，

For each Fortran function (and main) use the following

subroutine mysubroutine(.....)
#include <petsc/finclude/petscxxx.h>
use petscxxx
implicit none

make之前，需要在config.mk中设置CGNS_VERSION_FLAG，默认没有给值，会导致编译又问题，提示找不到cgnslib_h.f。解决办法为设置flag的值：CGNS_VERSION_FLAG=-DUSECGNSMODULE。

Instead of PETSC_NULL_OBJECT you must pass PETSC_NULL_XXX (for example PETSC_NULL_VEC) using the specific object type XXX that the function call is expecting.
