Question

我正在尝试创建一个makefile，这样我就可以编译多个C文件。这个makefile没有按预期工作，只在我运行make all时编译ex1并给出关于ex3的错误（参见错误日志）

CFLAGS=-Wall -g


all:
    make ex1
    make ex3

clean:
    rm -f ex1
    rm -f ex3

错误：

make all
make ex1
make[1]: Entering directory '/home/daniel/ownCloud/code/Learn C the hard way/Make'
cc -Wall -g    ex1.c   -o ex1
make[1]: Leaving directory '/home/daniel/ownCloud/code/Learn C the hard way/Make'
make ex3
make[1]: Entering directory '/home/daniel/ownCloud/code/Learn C the hard way/Make'
make[1]: *** No rule to make target 'ex3'.  Stop.
make[1]: Leaving directory '/home/daniel/ownCloud/code/Learn C the hard way/Make'
Makefile:5: recipe for target 'all' failed
make: *** [all] Error 2

Answer 1

以递归方式调用make是一个坏主意。您应该按如下方式编写makefile：

CFLAGS=-Wall -g

all: ex1 ex3

clean:
    rm -f ex1 ex3

makefile出错，编译多个C文件
