Windows下编译安装PETSc

本文记录在Windows下使用MinGW-w64编译安装PETSc的流程。

0、环境

操作系统	Windows 11
MSYS2	msys2-x86_64-20240507

1、开发环境

首先，下载并安装MSYS2，然后编辑PATH环境变量，添加mingw64相关路径：C:\msys64\mingw64\bin。
然后，下载并安装 msmpisetup.exe msmpisdk.msi 。

2、依赖

打开MSYS2 MINGW64控制台，备份/etc/pacman.d/mirrorlist.mingw64，

cp /etc/pacman.d/mirrorlist.mingw64 /etc/pacman.d/mirrorlist.mingw64.backup

然后编辑/etc/pacman.d/mirrorlist.mingw64以添加国内开源镜像源，并更新软件包数据库，

# Tsinghua
Server = https://mirrors.tuna.tsinghua.edu.cn/msys2/mingw/x86_64

pacman -Sy

运行以下命令安装依赖包，

pacman -S autoconf automake-wrapper bison bsdcpio make git \
mingw-w64-x86_64-toolchain patch python flex \
pkg-config pkgfile tar unzip mingw-w64-x86_64-cmake \
mingw-w64-x86_64-msmpi mingw-w64-x86_64-openblas mingw-w64-x86_64-jq

3. 下载PETSc源码

git clone -b release https://gitlab.com/petsc/petsc.git petsc
cd ./petsc/
git checkout v3.21.4

4、编译配置

export PETSC_ARCH=arch-mswin-c-debug-dmo
/usr/bin/python ./configure --prefix=/opt/petsc/arch-mswin-c-debug-dmo --with-debugging=1 --with-cc=mpicc --with-cxx=mpicxx --with-fc=mpif90 --with-openmp=1 --with-mpiexec='/C/Program\ Files/Microsoft\ MPI/Bin/mpiexec'

export PETSC_ARCH=arch-mswin-c-opt-dmo
/usr/bin/python ./configure --prefix=/opt/petsc/arch-mswin-c-opt-dmo --with-debugging=0 --with-cc=mpicc --with-cxx=mpicxx --with-fc=mpif90 --with-openmp=1 --with-mpiexec='/C/Program\ Files/Microsoft\ MPI/Bin/mpiexec'

 

5、编译与安装 

make PETSC_DIR=/mingw64/src/petsc PETSC_ARCH=arch-mswin-c-debug-dmo all
make PETSC_DIR=/mingw64/src/petsc PETSC_ARCH=arch-mswin-c-debug-dmo install

make PETSC_DIR=/mingw64/src/petsc PETSC_ARCH=arch-mswin-c-opt-dmo all
make PETSC_DIR=/mingw64/src/petsc PETSC_ARCH=arch-mswin-c-opt-dmo install
