"《GNUmake中文手册》是一本专为Linux/GNU系统用户编写的指南，由徐海兵翻译于2004年9月11日。该手册旨在帮助Linux爱好者快速掌握Makefile的基础知识，节省学习时间，提升技术水平。Makefile是GNU Make工具的核心组成部分，它在软件开发中起着关键作用，用于自动化编译、链接和清理等任务。 首先，手册从概述部分开始，介绍了Make的基本概念，包括Make的工作原理，以及对准备学习Makefile的读者的一些基本要求。读者将了解到Makefile的作用是根据目标文件的依赖关系来决定哪些源文件需要重新编译，从而简化了重复编译的过程。 章节二详细阐述了Makefile的结构和内容，包括Makefile的命名规则、如何包含其他Makefile、变量管理（如MAKEFILES、MAKEFILE_LIST等特殊变量）以及makefile的动态重建。理解这些内容有助于编写高效且灵活的Makefile。 在第三章，手册深入讲解了Makefile的规则，例如规则的语法、依赖关系的处理、文件名中的通配符使用（包括普通通配符和函数wildcard）、目录搜索机制，以及各种伪目标（如phony targets）、空目标文件和特殊目标的含义。此外，还讨论了多目标和多规则目标，以及静态模式的规则语法，这些都是实际编程中不可或缺的知识点。 通过阅读这份手册，读者不仅可以掌握Makefile的基础操作，还能学会如何利用Makefile进行高级的项目管理和构建优化，提升在Linux环境下的开发效率。对于想要深入理解并熟练运用Make工具的人来说，这是一份不可多得的参考资料。"

### 如何编写Makefile #### 概述 Makefile 是一种用于自动化构建过程的脚本文件，在 Linux 和 Unix 平台下广泛使用。通过 Makefile，开发者可以方便地管理项目中的多个源文件，并且能够自动完成项目的编译、链接等...

for a variable in makefile1 which is included by makefile2, could the makefile2 use the variable directly without importing in makefile2 and exporting in makefile1? Actually, it can be directly used! Give me an explicit example.

2023-05-30 上传
When Make is run, it will first process Makefile1 and execute its `all` target, which will print the value of `VAR1` and then invoke Makefile2's `all` target using `$(MAKE)`. When Makefile2's `all` ...

cur_makefile := $(lastword $(MAKEFILE_LIST)) give me some examples to explain this assignment

Suppose you have a Makefile called "myproject/Makefile" in the following directory structure: ``` myproject/ ├── src/ │ ├── file1.cpp │ ├── file2.cpp │ └── file3.cpp ├── include/ │ ...

makefile can not be used when making a shared object

2023-06-15 上传
To create a shared object using Makefile, you need to specify the appropriate compiler flags and linker flags for building shared objects. Here is an example Makefile for building a shared object: ...

make: *** No targets specified and no makefile found. Stop.

3. If you don't have a `Makefile` and still want to use `make`, you need to create a `Makefile` in your current directory. The `Makefile` is a text file that contains instructions for building your ...

Suppose we have a variable message with the value It's a beautiful day!. If we want to use this variable in a makefile command, we need to escape the single quote character (') so that the command is properly interpreted. We can do this using the subst function like so: 复制 escaped_message = $(subst $(squote),'\$(squote)',$(message)) escaped_message would have the value It'\$(squote)s a beautiful day! Did you made a mistake by "It'\$(squote)s a beautiful day!"?

This will replace any instances of the `$(squote)` variable (which is set to a single quote character) in the `message` variable with `'\$(squote)'`, effectively escaping the single quotes. ...

2023-07-28 上传
`ifdef` is a conditional directive in a Makefile that checks if a variable is ...This allows you to enable or disable certain flags or options in your Makefile based on the existence of a variable.

makefile A依赖于另外一个makefile B先执行，如何让当前make A中先执行makefile B

2023-05-09 上传
在makefile A中，可以使用以下命令来调用makefile B： ``` .PHONY: B all: B # do something B: cd path/to/makefile/B && $(MAKE) ``` 其中，`cd path/to/makefile/B`将目录切换到makefile B所在的目录，`$...

makefile +define

2023-07-27 上传
The "+define" you mentioned is not a standard directive in Makefile, but it can be used as a convention to pass custom-defined variables or flags to the make command. In a Makefile, you can define ...

what is the difference of "+" symbol and "force" command in makefile?
