本文记录在Windows下编译SLEPc的流程。

零、环境

操作系统	Windows 11
VS Code	1.92.1
MSYS2	msys2-x86_64-20250830

一、安装依赖

1.1、依赖

首先，下载并安装MSYS2，

打开MSYS2 MINGW64控制台，运行以下命令安装依赖包，

pacman -S git python base-devel mingw-w64-x86_64-toolchain mingw-w64-x86_64-msmpi

1.2 PETSc

参见<Windows下编译安装PETSc>

二、编译安装

2.1 下载源码

下载并解压slepc-3.22.1.zip

git clone https://github.com/slepc/slepc.git
cd ./slepc/
git checkout v3.22.1

2.2 构建

/usr/bin/python ./configure --prefix=/mingw64/arch-mswin-c-debug

2.3 编译与安装

make SLEPC_DIR=/mingw64/src/slepc-3.22.1 PETSC_DIR=/mingw64/src/petsc-v3.22.1 PETSC_ARCH=arch-mswin-c-debug
make SLEPC_DIR=/mingw64/src/slepc-3.22.1 PETSC_DIR=/mingw64/src/petsc-v3.22.1 install

三、使用SLEPc

# FindSLEPc
# ---------
#
# Locates the SLEPc library using pkg-config module SLEPc
#
# Imported Targets
# ^^^^^^^^^^^^^^^^
#
# This module defines the following IMPORTED target:
#
#  SLEPc::SLEPc        - the SLEPc library
#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# This module will set the following variables in your project:
#
#  SLEPc_FOUND          - if false, do not try to link to SLEPc
#  SLEPc_LIBRARIES      - a list of the full paths to all libraries
#  SLEPc_INCLUDE_DIRS   - a list of all include directories
#  SLEPc_VERSION        - the full version of SLEPc MAJOR.MINOR.PATCH
#  SLEPc_VERSION_MAJOR  - the MAJOR part of SLEPc_VERSION
#  SLEPc_VERSION_MINOR  - the MINOR part of SLEPc_VERSION
#  SLEPc_VERSION_PATCH  - the PATCH part of SLEPc_VERSION
#
# Setting these changes the behavior of the search
#  SLEPc_DIR - directory in which SLEPc resides
#  SLEPc_ARCH - build architecture
