make[1]: Entering directory error message
提问by noobler
I have a simple Makefile:
我有一个简单的 Makefile：
default:
@make build
@make run
build:
@javac Test.java > /dev/null
run:
@java Test
During compilation, make outputs:
在编译期间，输出：
make[1]: Entering directory `<current directory'>
...
make[1]: Leaving directory `<current directory'>
I need make to build without printing these messages. Does anybody know what the problem or how to suppress these messages?
我需要在不打印这些消息的情况下进行构建。有谁知道问题是什么或如何抑制这些消息？
Thanks
谢谢
edit: this happens regardless of the code. e.g. it happens with:
编辑：无论代码如何，都会发生这种情况。例如它发生在：
class Test {
public static void main(String[] args) {
System.out.println("HELLO WORLD");
}
}

make -ssuppresses other makefile messages also which might be important for developers. If you want to suppress "Entering/Leaving directory messages" only run makewith
make -s抑制其他可能对开发人员很重要的 makefile 消息。如果要抑制“进入/离开目录的消息”只运行make与
make --no-print-directory
make --no-print-directory

Change maketo make -s:
更改make为make -s：
default:
@make -s build
@make -s run
Better still:
更好的是：
default:
@$(MAKE) -s build
@$(MAKE) -s run
Even better:
更好的是：
default: run
build:
@javac Test.java > /dev/null
run: build
@java Test
