c++ - 编译包含 PETSc 库的 C++ 代码。make: 没有规则来制作目标错误信息

问题描述

我对使用这里讨论的开源代码很感兴趣。此处讨论了有关如何运行代码的框架和一些说明。为了能够使用代码，首先应该安装PETSc。我已经这样做了，它似乎已正确安装。当我尝试按照论文make topopt中给出的说明（第 2.2 节）运行时，问题就出现了。在GitHub 上有一个地方，按照本文中给出的说明，我进行了以下更改：和. 运行后出现以下错误：makefile_refPETSC_DIR=\home\myusername\petscPETSC_ARCH=arch-linux-c-debugmake -d topopt

解决方案

有一个makefile_ref地方按照本文中给出的说明进行了以下更改[...]

如果没有指定要读取的生成文件的显式选项，该make实用程序会通过几个替代名称查找输入文件。makefile_ref不是其中之一。我将文件名的“_ref”部分作为“参考”的助记符，从这个角度来看，意图似乎是您复制makefile_ref到，比如说，makefile（默认情况下查找的文件名之一），make 并修改复制到适合您的环境。
