[C++] 江添亮さんのC++Windowsで入門する方法(MinGW)(64bit Windows11)　Make編　

https://ezoeryou.github.io/cpp-intro

に基づいて書いてます。

MinGWに付属する GNU make ですが、ファイル名が mingw32-make.exe となっていると思います。 このままでは使いにくいのでファイルをコピーして make.exe にリネームした方がよいでしょう。

windowsで、timeコマンド touchコマンドをつかうには　gitbashが必要だ。

(1) https://gitforwindows.org/ にアクセスしてください。

(2) [Download]をクリックしてください。

あとは適当にインストールで。C:\Program Files\Git\git-bash.exe

furcr@furcraea_built MINGW64 /c/samples/ehararyu_cpp_sample/cpp/source010203
$ make
makefile:2: *** missing separator. Stop.

はmakefile の改行のあとが　space だから　Tab　にする。

program : source.cpp
    cat source.cpp > program

source : source01 source02 source03
    cat source01 source02 source03 > source

を

program : source
	cat source > program

source : source01 source02 source03
	cat source01 source02 source03 > source

うまくいった。
