Make默认情况下不支持此功能，其他回答已经展示了如何自动提取可能目标的列表。

然而，如果您想对清单有更多的控制，而不产生任何副作用(例如使用. phony目标标记文档，这阻止了使用目标名称作为Make用来决定需要重建哪些目标的实际文件的逻辑)，您可以为文档发明自己的语法。我更喜欢这样使用###:

CPUS ?= $(shell nproc)
MAKEFLAGS += -j $(CPUS) -l $(CPUS) -s

# Basic paths
PREFIX  ?= usr
BINDIR  ?= $(PREFIX)/bin
ETCDIR  ?= etc
MANDIR  ?= $(PREFIX)/share/man
# ...

### help: Show help message (default target)
# use "help" as the default target (first target in the Makefile)
.PHONY: help
help:
    @printf "%s\n\n" "make: List of possible targets:"
    @grep '^### .*:' $(lastword $(MAKEFILE_LIST)) | sed 's/^### \([^:]*\): \(.*\)/\1:\t\2/' | column -ts "$$(printf '\t')"

### install: Install all files in $PREFIX (used by debian binary package build scripts)
install:
    install -D -o root -g root -m 755 ...
    ...

### release: Increase package version number
release:
    debchange --release

(像往常一样，缩进文件必须精确地从一个制表器开始，但stackoverflow不能正确地再现该细节。)

输出如下所示:

$ make
make: List of possible targets:

help:      Show help message (default target)
install:   Install all files in $PREFIX (used by debian binary package build scripts)
release:   Increase package version number

This works because only lines starting with ### and having a : character are considered as the documentation to output. Note that this intentionally does not extract the actual target name but fully trusts the documentation lines only. This allows always emitting correct output for very complex Makefile tricks, too. Also note that this avoids needing to put the documentation line on any specific position relative to actual rule. I also intentionally avoid sorting the output because the order of output can be fully controlled from the Makefile itself simply by listing the documentation lines in preferred order.

显然，您可以发明任何其他您喜欢的语法，甚至可以做一些

### en: install: Install all files in $PREFIX
### fi: asennus: asenna kaikki tiedostot hakemistoon $PREFIX

并且只打印与当前语言环境匹配的行，以支持多种语言，并具有别名来本地化目标名称:

.PHONY: asennus
asennus: install

最重要的问题是为什么要列出目标?您想要实际的文档还是某种调试信息?

对于讨厌AWK的人来说，为了简单起见，这个精巧的设计适合我:

help:
  make -qpRr $(lastword $(MAKEFILE_LIST)) | egrep -v '(^(\.|:|#|\s|$)|=)' | cut -d: -f1

(对于在Makefile外部使用，只需删除$(最后一个词…)或将其替换为Makefile路径)。

This solution will not work if you have "interesting" rule names but will work well for most simple setups. The main downside of a make -qp based solution is (as in other answers here) that if the Makefile defines variable values using functions - they will still be executed regardless of -q, and if using $(shell ...) then the shell command will still be called and its side effects will happen. In my setup often the side effects of running shell functions is unwanted output to standard error, so I add 2>/dev/null after the make command.

如果为make安装了bash补全，补全脚本将定义一个函数_make_target_extract_script。该函数用于创建一个sed脚本，该脚本可用于以列表的形式获取目标。

像这样使用它:

# Make sure bash completion is enabled
source /etc/bash_completion 

# List targets from Makefile
sed -nrf <(_make_target_extract_script --) Makefile

我最喜欢的答案是Chris Down在Unix & Linux Stack Exchange上发布的。我将引用。

这是make的bash完成模块获取列表的方式: 使得qp | awk - f ': ' ' / ^ [a-zA-Z0-9] [^ $ # \ / \ t =]*:([^=]|$)/ { 分(1美元,/ /);(我的)打印一个[我]}’ 它输出以换行符分隔的目标列表，不进行分页。

用户Brainstone建议使用sort -u来删除重复的条目:

make -qp | awk -F':' '/^[a-zA-Z0-9][^$#\/\t=]*:([^=]|$)/ {split($1,A,/ /);for(i in A)print A[i]}' | sort -u

这显然在很多情况下都不起作用，但如果你的Makefile是由CMake创建的，你可能可以运行make help。

$ make help
The following are some of the valid targets for this Makefile:
... all (the default if no target is provided)
... clean
... depend
... install
etc
