以下行在 makefile 中做了什么？
What does the following line do in makefiles?
这一行在 makefile 中的作用是什么？
-include Makefile.add_exp430.defines
Makefile.add_exp430.defines是一个文件还是多个文件的复杂？
include的减号前缀是干什么用的？
谢谢。
The include directive tells make to suspend reading the current
makefile and read one or more other makefiles before continuing
To ignore errors in a recipe line, write a ‘-’ at the beginning of the
line’s text (after the initial tab). The ‘-’ is discarded before the
line is passed to the shell for execution.
假设您的 Makefile 是：
-include some_inexisting_file
all:
@echo "Yellow!"
运行 make all 将输出 Yellow!
没有破折号，输出变为：Makefile:2: some_inexisting_file: No such file or directory
