F90 = gfortran
FFLAGS = #-O3, this is an optimizer which makes loops more efficient
EXECUTABLE = quad

我正在尝试编译 Fortran Andrew R. Winters notes 中列出的 Fortran 代码。我在这里列出版本以防这些注释从网络上消失。

但是当运行 make 构建这些文件时，我得到了以下错误

Makefile:12: *** missing separator. Stop.

在看到其他 make 文件问题后，我觉得问题是由于 Sublime Text 将我的制表符转换为空格，正如我最初设置的那样。（对于 python）。我不想打扰它。

我尝试了 to detect where the tabs were supposed to be，但它给出了不同的结果就像我无法弄清楚 ^M 是什么意思。

然后我尝试 .editorconfig file approach 告诉 Sublime Text 不要自动修复标签。也无济于事。

我也试过一个说使用 u09 Unicode 字符的答案，我现在找不到了。

我正在复制文件 Constants.f90 functions.f90 QuadExample.f90 quadratureRules.f90 下面是更好的主意

常量.f90

我打开了 Sublime Text > 首选项 > 设置并将“Makefile”添加到 "file_exclude_patterns":

在那之后，我用gedit打开它，实际上将空格转换为制表符。瞧，事情成功了。
