suitesparse-metis-for-windows 1.3.1 安装包内附SuiteSparse 4.5.1, Metis 5.1.0和 lapack 3.4.1

Github上面由整理好的suitesparse包适合在Windows安装 https://github.com/jlblancoc/suitesparse-metis-for-windows，并附有详细的安装指导，但是会有一点bug

问题1：metis/GKlib/gk_arch.h中有个bug，从C++11开始标准库中已经支持rint函数了,VS 2013开始支持这一函数,修复方式

#ifdef __MSC__

/* MSC does not have rint() function */

#if (_MSC_VER < 1800)　　/*visual studio 2013编译器版本*/

 #define rint(x) ((int)((x)+0.5))

#endif

/* MSC does not have INFINITY defined */

#ifndef INFINITY

#define INFINITY FLT_MAX

#endif

#endif

#endif

安装后测试方式

1.在环境变量中设置SuiteSparse_DIR位置是SuiteSoarse的安装位置，例如C:\Program Files (x86)\Suitesparse

2.测试程序

#include <iostream>

#include "Eigen/Eigen"

#include "Eigen/SPQRSupport"

using namespace Eigen;

int main() {

    SparseMatrix < double > A(, );

    std::vector < Triplet < double > > triplets;

    // 初始化非零元素

    int r[] = { , ,  };

    int c[] = { , ,  };

    double val[] = { 6.1, 7.2, 8.3 };

    for (int i = ; i < ; ++i)

        triplets.push_back(Triplet < double >(r[i], c[i], val[i]));

    // 初始化稀疏矩阵

    A.setFromTriplets(triplets.begin(), triplets.end());

    std::cout << "A = \n" << A << std::endl;

    // 一个QR分解的实例

    SPQR < SparseMatrix < double > > qr;

    // 计算分解

    qr.compute(A);

    // 求一个A x = b

    Vector4d b(, , , );

    Vector4d x = qr.solve(b);

    std::cout << "x = \n" << x;

    std::cout << "A x = \n" << A * x;

    getchar();

    return ;

}

2.相同文件夹下的CMakeLists.txt

# -----------------------------------------------

# Test CMake script for building against SuiteSparse

#  http://code.google.com/p/suitesparse-metis-for-windows/

# Created by Jose Luis Blanco (University of Almeria)

# Updated by jesnault (jerome.esnault@inria.fr) --

PROJECT(CholmodExample)

cmake_minimum_required(VERSION 2.8)

# ------------------------------------------------------------------

# Detect SuiteSparse libraries:

# If not found automatically, set SuiteSparse_DIR in CMake to the

# directory where SuiteSparse was built.

# ------------------------------------------------------------------

LIST(APPEND CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/../../cmakemodule/") # Add the directory where FindSuiteSparse.cmake module can be found.

set(SuiteSparse_USE_LAPACK_BLAS ON)

find_package(SuiteSparse QUIET NO_MODULE)  # 1st: Try to locate the *config.cmake file.

if(NOT SuiteSparse_FOUND)

        #set(SuiteSparse_VERBOSE ON)

        find_package(SuiteSparse REQUIRED) # 2nd: Use FindSuiteSparse.cmake module

        include_directories(${SuiteSparse_INCLUDE_DIRS})

else()

        message(STATUS "Find SuiteSparse : include(${USE_SuiteSparse})")

        include(${USE_SuiteSparse})

endif()

MESSAGE(STATUS "SuiteSparse_LIBS: ${SuiteSparse_LIBRARIES}")

# ------------------------------------------------------------------

#   End of SuiteSparse detection

# ------------------------------------------------------------------

# ------------------------------------------------------------------

# Declare an example program:

# ------------------------------------------------------------------

ADD_EXECUTABLE(cholmod-test cholmod-test.c)

TARGET_LINK_LIBRARIES(cholmod-test ${SuiteSparse_LIBRARIES})

3.命名文件夹src,并将上面两个文件放进去，并创建build文件夹，利用cmake的configure和generate Visual Studio2013工程文件，直接生成就可以(根据自己的FindSuiteSparse.cmake文件的位置设置CMakeLists.txt中变量CMAKE_MODULE_PATH的位置)即可

4.如果不使用cmake工具，记得在VS的工程属性中设置lapack和suitesparse库的安装位置，链接如下库即可
