How to compile a C program with make on Mac OS X Terminal
提问by Raphael Teubner
I recently bought a Macbook Pro and I want to do some coding in C with the terminal.
我最近买了一台 Macbook Pro，我想用终端用 C 语言编写一些代码。
I'm able to compile the code with this command:
我可以使用以下命令编译代码：
gcc filename.c –o filename
But I want to compile it with the make command because I know it is best practice and I want to follow best practice.
但我想用 make 命令编译它，因为我知道这是最佳实践，我想遵循最佳实践。
make filename cc filename.c -o filename
This command is giving me the following output:
这个命令给了我以下输出：
make: Nothing to be done for `ex01'.
make: *** No rule to make target `cc'. Stop.
Note that I have installed Xcode and Xcode developer command line tools and in the folder /usr/binI see the makeand makefileproperties.
请注意，我已经安装了 Xcode 和 Xcode 开发人员命令行工具，并且在文件夹/usr/bin 中我看到了make和makefile属性。
Does anyone have any hint on what should I do to be able to compile with makefile and cc argument?
有没有人对我应该怎么做才能使用 makefile 和 cc 参数进行编译有任何提示？

Create a file called Makefileon the same path with this content:
Makefile使用此内容创建一个在同一路径上调用的文件：
CC = cc
CFLAGS = -std=c99 -pedantic -Wall
OBJECTS = filename.o
all: appname
filename.o: filename.c
$(CC) $(CFLAGS) -c filename.c
appname: $(OBJECTS)
$(CC) $(OBJECTS) -o appname
clean:
rm -f *.o appname
Then run:
然后运行：
make
Of course, replace appnamewith the name of your program
当然，替换appname为你的程序名称
Note: There must be a "tab" (not spaces) before
注意：之前必须有一个“制表符”（不是空格）
$(CC) $(CFLAGS) -c filename.c
and
和
$(CC) $(OBJECTS) -o appname

I was following the same tutorial, and ran into a similar problem.
我正在遵循相同的教程，并遇到了类似的问题。
I don't know what exactly you did, but I think the mistake was running the wrong command. You typed make filename cc filename.c -o filename, but the tutorial instructed us to use make filename, without the cc filename.c -o filenamepart. Maybe you read an old version?
我不知道你到底做了什么，但我认为错误是运行了错误的命令。您输入了make filename cc filename.c -o filename，但教程指示我们使用make filename，而没有cc filename.c -o filename部分。也许你读的是旧版本？
And, make filenameworks fine, You don't need a Makefile.
而且，make filename工作正常，您不需要 Makefile。
FYI, Here's how I ran into the problem and how I solved it:
仅供参考，这是我遇到问题的方式以及解决方法：
typed the code below, and saved it in a file named "ex1"
int main(int argc, char *argv[]) { puts("Hello world."); return 0; }- typed
make ex1in terminal - got error message
make: Nothing to be done for 'ex1'.
输入下面的代码，并将其保存在名为“ex1”的文件中
int main(int argc, char *argv[]) { puts("Hello world."); return 0; }make ex1在终端输入- 收到错误信息
make: Nothing to be done for 'ex1'.
As you can see, my mistake was that the file name of the source code should be ex1.c, NOT ex1.
如您所见，我的错误是源代码的文件名应该是ex1.c，而不是ex1。
And as I change the file name to ex1.c, and executed make ex1, it worked.
当我将文件名更改为 ex1.c 并执行时make ex1，它起作用了。
