gcc - gcc 在 mac os catalina 上找不到头文件

Question

我正在安装一个无法用 Apple 的 gcc 编译的包（称​​为 CLASS，在宇宙学中广泛使用）。

我尝试通过 homebrew (gcc-9) 和 anaconda 分别安装 gcc。但是他们都找不到标准的 C 库文件，例如 stdio.h、math.h 等。我看到这个问题在 mac 中很常见。我在/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/. 专注于 anaconda gcc（版本 4.8.5），然后我将文件复制到/Users/satadru/anaconda2/include/. 现在简单的 C 代码，例如“hello world”代码运行良好。但是当我尝试安装 CLASS 包时，我得到了由有问题的库文件引起的错误：stdio.h，math.h！当我尝试使用自制 gcc-9 安装软件包时（将库文件复制到其相关目录之后），我得到了同样的错误。我知道很多人可以毫无问题地在 catalina 上运行该软件包。

现在我有以下问题：

1. 所有标准 C 库头文件都相同吗？也就是说，anaconda gcc 4.8.5 还是 gcc-9，头文件都一样吗？头文件是否在不同的操作系统上有所不同，比如 linux 或 mac os？

2. anaconda gcc 是否在以下位置查找头文件/Users/satadru/anaconda2/include/？

3. 在将所有头文件复制到 之前/Users/satadru/anaconda2/include/，该目录中存在一些。为什么anaconda gcc安装的时候没有把自己所有的头文件都放在这个目录下？我们在 linux 操作系统上做的时候是一样的吗？

4. 如何解决我的问题？我联系了包的所有者，他说他自己在 mac os catalina 上运行代码，但从未遇到过这个问题。
