環境はwindows10(32bit), gcc-5.3.0, cmake-3.4.0, GNUmake-3.81です。

defaultの設定ではVisual Studio付属のnmakeを使ってのbuildになってしまうため、`-G "MSYS
Makefiles"`というオプションを付けてcmakeを行いました。

directory構成は、  
sample/  
├ .#main.c  
└ CMakeLists.txt  
で、それぞれのソースコードは末尾に示します。<https://m-tmatma.github.io/cmake/cmake-
helloworld.html>から内容は引用し、main.cを.#main.cに変えただけのものです。これをsample内で`cmake -G "MSYS
Makefiles"`とすると、

```

    -- The C compiler identification is GNU 5.3.0
    -- The CXX compiler identification is GNU 5.3.0
    -- Check for working C compiler: C:/Pragram Files/MinGW/bin/gcc.exe
    -- Check for working C compiler: C:/Program Files/MinGW/bin/gcc.exe -- works
    -- Detecting C compiler ABI info
    -- Detecting C compiler ABI info - done
    -- Detecting C compile features
    -- Detecting C compile features - done
    -- Check for working CXX compiler: C:/Program Files/MinGW/bin/g++.exe
    -- Check for working CXX compiler: C:/Program Files/MinGW/bin/g++.exe -- works
    -- Detecting CXX compiler ABI info
    -- Detecting CXX compiler ABI info - done
    -- Detecting CXX compile features
    -- Detecting CXX compile features - done
    -- Configuring done
    -- Generating done
    -- Build files have been written to: C:/somedir/sample
    
```

のようにoutputが得られ、成功します(生成されたMakefileは末尾に載せます)。  
しかし、ここで`make`を実行すると、

```

    Makefile:126: *** missing separator.  Stop.
    
```

というerrorを吐きます。126行目は、

```

    .#main.obj: .#main.c.obj
    
```

という行です。

ファイル名に#があるとエラーを吐くというところまでは分かりました。ファイル名を変更せずにこのエラーを解決するにはどうすればよいのでしょうか。

以下ソースコード

.#main.c

```

    #include <stdio.h>
    
    int main()
    {
        printf("Hello World\n");
        return 0;
    }
    
```

CMakeLists.txt

```

    cmake_minimum_required(VERSION 2.6.4)
    
    # define a variable of project name
    set( project_name "HelloWorld")
    
    # set the project as the startup project
    set_property(DIRECTORY PROPERTY VS_STARTUP_PROJECT ${project_name} )
    
    # define a project name
    project (${project_name})
    
    # define a variable SRC with file GLOB
    file(GLOB SRC *.c)
    
    # define sources files of an executable
    add_executable(${project_name} ${SRC})
    
```

question
c makefile cmake
ファイル名が.#で始まるファイルに対して、cmakeで作製されたmakefileをmakeするとエラーを吐く
> ファイル名に#があるとエラーを吐くというところまでは分かりました。ファイル名を変更せずにこのエラーを解決するにはどうすればよいのでしょうか。

[makeのマニュアル](https://www.gnu.org/software/make/manual/make.html#Makefile-
Contents)によると、`#`をコメントではなく、リテラルとして使用したい場合は、`.\\#main.c`のように、バックスラッシュ(`\`)でエスケープするとあります。

そのため、Makefile内の`.#main`を`.\\#main`に置換すれば、該当エラーは解決するはずです。
