在 Ubuntu 中编译 SuiteSparse，在安装 CHOLMOD 时中断

Question

我已经从以下GitHub下载了SuiteSparse的.zip。我正在尝试在 Ubuntu 中安装/编译 C/C++ 库。我正在使用适用于Linux的Windows子系统，并从Microsoft商店安装了Ubuntu。

SuiteSparse指令说要 cd 到 SuiteSparse-5.5.0 目录，然后键入make。在这里制作文件。自述文件建议我需要 make、g++、gcc 和 cmake，所以我使用sudo apt install <package name>安装了它们。这是我从make 2>error收到的错误消息：

我已经关闭了我的防病毒软件，它一直在阻止 makefile 在某些文件夹中写入。可能出现什么问题？似乎makefile试图从CHOLMOD开始安装一堆库，并在这样做时停滞不前。我读过一些相关的问题。第一个似乎不适用于这里，因为我没有更改 PATH，第二个建议使用我已经在做的 Metis。

安装 LLAPACK 和 OpenBLAS 开发库。在 Ubuntu 上，命令是：

sudo apt install liblapack-dev  libopenblas-dev
