software），经由读取“makefile”的文件以自动化建构软件。它是一种转化文件形式的工具，转换的目标称为“target”；与此同时，它也检查文件的依赖关系，如果需要的话，它会调用一些外部软件来完成任务。它的依赖关系检查系统非常简单，主要根据依赖文件的修改时间进行判断。大多数情况下，它被用来编译源代码，生成结果代码，然后把结果代码连接起来生成可执行文件或者库文件。它使用叫做“makefile”的文件来确定一个target文件的依赖关系，然后把生成这个target的相关命令传给shell去执行。</p><p><del>由此可见，Makefile可以抽象理解为有make这个解释器去执行的shell脚本</del></p><p>运行make

title="Makefile扩展语法"></a>Makefile扩展语法</h1><h3 id="Makefile手动变量"><a href="#Makefile手动变量" class="headerlink" title="Makefile手动变量"></a>Makefile手动变量</h3><p>下面是一个Makefile的一部分:</p><figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br></pre></td><td class="code"><pre><span class="line">build: src</span><br><span class="line">cd src</span><br><span class="line">gcc -c main.c -o main.o</span><br><span class="line">gcc -c ui.c -o ui.o</span><br><span class="line">gcc -c src.c -o src.o</span><br></pre></td></tr></table></figure><p>我们可以看到[.o]文件的字符串被重复了三次，如果我们的工程需要加入一个新的[.o]文件，那么我们需要在三个地方加（应该是四个地方，还有一个地方在clean中，这里并没有展示）。当然，我们的makefile并不复杂，所以在两个地方加也不累，但如果makefile变得复杂，那么我们就有可能会忘掉一个需要加入的地方，而导致编译失败。所以，为了makefile的易维护，在makefile中我们可以使用变量。makefile的变量也就是一个字符串，理解成C语言中的宏可能会更好</p><p>比如，我们声明一个变量，叫objects, OBJECTS, objs, OBJS, obj, 或是 OBJ。我们在makefile一开始就这样定义:</p><figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br></pre></td><td class="code"><pre><span class="line">objects = main.o src.o ui.o</span><br><span class="line">outs : $(objects)</span><br></pre></td></tr></table></figure><p>于是，我们就可以很方便地在我们的makefile中以“$(objects)”的方式来使用这个变量了。</p><figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">gcc -o outs $(objects)</span><br></pre></td></tr></table></figure><p>同理。我们也可以使用系统自带变量。</p><p>有些有默认值，有些没有。比如常见的几个：</p><blockquote><p>CPPFLAGS : 预处理器需要的选项 如：-I<br>CFLAGS：编译的时候使用的参数 –Wall –g -c<br>LDFLAGS ：链接库使用的选项 –L -l</p></blockquote><h3 id="Makefile自动变量"><a href="#Makefile自动变量" class="headerlink" title="Makefile自动变量"></a>Makefile自动变量</h3><p>Makefile提供了很多自动变量，但常用的为以下三个。这些自动变量只能在规则中的命令中使用，其它地方使用都不行。</p><ul><li><p>$@ –> 规则中的目标</p></li><li><p>$< –> 规则中的第一个依赖条件</p></li><li><p>$^ –> 规则中的所有依赖条件</p></li></ul><p>例如:</p><figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">app: main.c func1.c fun2.c gcc $^ - o $@</span><br></pre></td></tr></table></figure><p>其中：$^表示main.c func1.c fun2.c，$<表示main.c，$@表示app。</p><h3 id="Makefile模式规则"><a href="#Makefile模式规则" class="headerlink" title="Makefile模式规则"></a>Makefile模式规则</h3><p>模式规则是在目标及依赖条件中使用%来匹配对应的文件，比如在目录下有main.c, src.c, ui.c三个文件，对这三个文件的编译可以由一条规则完成：</p><figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">%.o:%.c $(CC) –c $< -o $@</span><br></pre></td></tr></table></figure><p>这条模式规则表示：</p><p>main.o由main.c生成， src.o由src.c生成， src.o由src.c生成</p><h3 id="Makefile-目标"><a href="#Makefile-目标" class="headerlink" title="Makefile 目标"></a>Makefile 目标</h3><p>一般来说，make的最终目标是makefile中的第一个目标，而其它目标一般是由这个目标连带出来的。这是make的默认行为。当然，一般来说，你的makefile中的第一个目标是由许多个目标组成，你可以指示make，让其完成你所指定的目标。要达到这一目的很简单，需在make命令后直接跟目标的名字就可以完成（如前面提到的“make clean”形式）</p><p>任何在makefile中的目标都可以被指定成终极目标，但是除了以“-”打头，或是包含了“=”的目标，因为有这些字符的目标，会被解析成命令行参数或是变量。甚至没有被我们明确写出来的目标也可以成为make的终极目标，也就是说，只要make可以找到其隐含规则推导规则，那么这个隐含目标同样可以被指定成终极目标。</p><p>使用指定终极目标的方法可以很方便地让我们编译我们的程序，例如下面这个例子：</p><figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br></pre></td><td class="code"><pre><span class="line">.PHONY: all</span><br><span class="line">all: arg1 arg2 arg3</span><br></pre></td></tr></table></figure><p>从这个例子中，我们可以使用“make all”命令来编译所有的目标（如果把all置成第一个目标，那么只需执行“make”），我们也可以使用 “make arg2”来单独编译目标“arg2”。</p><p>即然make可以指定所有makefile中的目标，那么也包括“伪目标”，于是我们可以根据这种性质来让我们的makefile根据指定的不同的目标来完成不同的事。</p><p>下面请看这个例子</p><figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br></pre></td><td class="code"><pre><span class="line">claen: out</span><br><span class="line">rm -rf out</span><br></pre></td></tr></table></figure><p>如果当前目录下存在名为clean的文件，则该命令不执行。</p><p>最稳妥的做法是下面这样:</p><figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line">.PHONY : clean</span><br><span class="line"></span><br><span class="line">clean :</span><br><span class="line">-rm -rf out</span><br></pre></td></tr></table></figure><p>.PHONY意思表示clean是一个“伪目标”，伪目标一般没有依赖的文件。而在rm命令前面加了一个小减号的意思就是，也许某些文件出现问题，但不要管，继续做后面的事。当然，clean的规则不要放在文件的开头，不然，这就会变成make的默认目标。</p><h3 id="Makefile返回值"><a href="#Makefile返回值" class="headerlink" title="Makefile返回值"></a>Makefile返回值</h3><p>一般地，Makefile有三个返回值:</p><ul><li>0 —— 表示成功执行。</li><li>1 —— 如果make运行时出现任何错误，其返回1。</li><li>2 —— 如果你使用了make的“-q”选项，并且make使得一些目标不需要更新，那么返回2。</li></ul><p>实际上一个Makefile可能不仅只有这三个返回值。</p><h3 id="引进其他Makefile"><a href="#引进其他Makefile" class="headerlink" title="引进其他Makefile"></a>引进其他Makefile</h3><p>只需要在Makefile开头加入</p><figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">include <src/Makefile></span><br></pre></td></tr></table></figure><h3 id="Makefile判断"><a href="#Makefile判断" class="headerlink" title="Makefile判断"></a>Makefile判断</h3><p>请看下面的例子:</p><figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br></pre></td><td class="code"><pre><span class="line">ifeq ($(CC),gcc)</span><br><span class="line"> ld=$(ld)</span><br><span class="line">else</span><br><span class="line"> ld=$(ld.lld)</span><br><span class="line">endif</span><br></pre></td></tr></table></figure><p>上面代码判断当前编译器是否 gcc ，然后指定不同ld。</p><h3 id="附录-一个简单的Makefile例子"><a href="#附录-一个简单的Makefile例子" class="headerlink" title="附录:一个简单的Makefile例子"></a>附录:一个简单的Makefile例子</h3><figure class="highlight plaintext"><table><tr><td
