摘要

项目依赖环境太多，需要一个一个编译安装然后再做依赖，正好一个一个记录一下过程和出现的问题。

安装mingw

教程：win10上安装mingw

下载lapack库

lapack官网下载列表
lapck-3.11.tar.gz直接下载地址(github)
lapack-3.11.tar.gz本站下载地址

cmake配置

1. Configure 选中 MinGW Makefiles
2. 处理配置项
   
3. Configure && Generate

编译及安装

1. cd build目录
2. mingw32-make.exe -j 8
3. mingw32-make.exe -j 8 install

报错处理(多重定义问题)

解决办法

在build/lapack/SRC/CMakeFiles/lapack64.dir/link.txt文件中gfortran配置参数中添加--allow-multiple-definition参数

E:\program\mingw64\bin\gfortran.exe  -frecursive -fdefault-integer-8 -g -shared -o ..\bin\liblapack64.dll -Wl,--out-implib,..\lib\liblapack64.dll.a -Wl,--major-image-version,3,--minor-image-version,11 -Wl,--whole-archive CMakeFiles\lapack64.dir/objects.a -Wl,--no-whole-archive @CMakeFiles\lapack64.dir\linkLibs.rsp -Wl,--allow-multiple-definition,--output-def,lapack64.def

然后重新编译就能过了。
