从源代码构建 SciPy 时出现分段错误（核心转储）

Question

我尝试按照本教程中提到的步骤在我的 Linux 机器上从源代码构建 SciPy 库。

在第 13 步中，当尝试使用python3 runtests.py -v测试构建时，会引发分段错误。

我正在使用一个名为scipydev的 conda 虚拟环境

以下是相关日志：

我怀疑 LAPACK 或 BLAS 库可能会导致这种情况，但我不确定。 任何帮助将不胜感激。

不一定是答案，但可能是线索。

从源代码构建 python 包时，一些代码需要 C 编译器，重要的是在安装之前检查你有什么和需要什么，然后获取必要的编译器版本。

这是一个罕见的案例，但仍然值得一试。
