本文記錄在Windows下編譯SLEPc的流程。

零、環境

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

一、安裝依賴

1.1、依賴

首先，下載并安裝MSYS2，

打開MSYS2 MINGW64控制臺，運行以下命令安裝依賴包，

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

1.2?PETSc

?參見<Windows下編譯安裝PETSc>

二、編譯安裝

2.1 下載源碼

下載并解壓slepc-3.22.1.zip?

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

2.2 構建

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

2.3 編譯與安裝

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
