<h2 id="什么是交叉编译"><a href="#什么是交叉编译" class="headerlink" title="什么是交叉编译"></a>什么是交叉编译</h2><p>交叉编译是在一个平台上生成另一个平台上的可执行代码。同一个体系结构可以运行不同的操作系统；同样，同一个操作系统也可以在不同的体系结构上运行。</p>
<h2 id="为什么要用交叉编译"><a href="#为什么要用交叉编译" class="headerlink" title="为什么要用交叉编译"></a>为什么要用交叉编译</h2><p>原因主要有以下几点：</p>
<ul>
<li>目的平台上不允许或不能够安装我们所需要的编译器，而我们又需要这个编译器的某些特征；</li>
<li>目的平台上的资源贫乏，无法运行我们所需要编译器；</li>
<li>目的平台还没有建立，连操作系统都没有，根本谈不上运行什么编译器。</li>
</ul>

<h3 id="添加环境变量"><a href="#添加环境变量" class="headerlink" title="添加环境变量"></a>添加环境变量</h3><p>在 ～/.bashrc 中加入以下内容</p>

<p>现在，终端运行如下命令，如果没有提示命令不存在，则说明安装成功</p>

<h3 id="编译一个HelloWorld"><a href="#编译一个HelloWorld" class="headerlink" title="编译一个HelloWorld"></a>编译一个HelloWorld</h3><p>国际惯例，编译一个 HelloWorld</p>

<p>运行结果如图，现在在PC机上是无法运行这个二进制文件的<br><img src="https://renshengjihe-1257851699.cos.ap-guangzhou.myqcloud.com/191201-RaspberryPiTools/run0nPC.png" alt="run0nPC"></p>
<h2 id="建立-PC-和树莓派的通信方式"><a href="#建立-PC-和树莓派的通信方式" class="headerlink" title="建立 PC 和树莓派的通信方式"></a>建立 PC 和树莓派的通信方式</h2><p>通过 scp 将生成的二进制文件复制到树莓派下，这里记录一下用 ssh 免密登录的配置过程</p>
<h3 id="在-PC-机上执行"><a href="#在-PC-机上执行" class="headerlink" title="在 PC 机上执行"></a>在 PC 机上执行</h3><figure class="highlight sh"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">ssh-keygen</span><br></pre></td></tr></table></figure>
<p>一路回车，最后会在用户目录下生成一个 .ssh 目录，将其中的公钥文件 id_rsa.pub 复制到树莓派下备用</p>
<figure class="highlight sh"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">scp ~/.ssh/id_rsa.pub [email protected]:/home/pi/</span><br></pre></td></tr></table></figure>
<p>此处用户名和ip看各自情况而定。</p>
<h3 id="在树莓派上执行"><a href="#在树莓派上执行" class="headerlink" title="在树莓派上执行"></a>在树莓派上执行</h3><p>在树莓派的 .ssh 目录下新建一个 <code>authorized_keys</code> 文件，若已存在，跳过此步骤</p>
<figure class="highlight sh"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">touch authorized_keys</span><br></pre></td></tr></table></figure>
<p>把刚才 scp 到树莓派下的 PC 机的公钥文件追加到 <code>authorized_keys</code> 末尾</p>
<figure class="highlight sh"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">cat ~/id_rsa.pub >> ~/.ssh/authorized_keys</span><br></pre></td></tr></table></figure>
<p>现在，主机再 ssh 到树莓派将直接使用密钥验证，无需输入密码。</p>
<h3 id="每次都要敲-ip-太麻烦？"><a href="#每次都要敲-ip-太麻烦？" class="headerlink" title="每次都要敲 ip 太麻烦？"></a>每次都要敲 ip 太麻烦？</h3><p>在 PC 机 .ssh 目录下新建一个 config 文件，在其中配置如下信息：</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">Host pi</span><br><span class="line">Hostname 192.168.123.106</span><br><span class="line">Port 22</span><br><span class="line">User pi</span><br></pre></td></tr></table></figure>
<p>这样就可以通过主机名 pi 来访问到树莓派了，如下</p>
<figure class="highlight sh"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">ssh pi</span><br></pre></td></tr></table></figure>
<h3 id="运行HelloWorld"><a href="#运行HelloWorld" class="headerlink" title="运行HelloWorld"></a>运行HelloWorld</h3><p>把上一步编译出的二进制文件复制到树莓派下</p>
<figure class="highlight sh"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">scp <span class="built_in">test</span> pi:/home/pi</span><br></pre></td></tr></table></figure>

<h2 id="Makefile-文件编写"><a href="#Makefile-文件编写" class="headerlink" title="Makefile 文件编写"></a>Makefile 文件编写</h2><p>通过 Makefile 文件来更方便的进行编译和文件复制，以下是我写的一个简单的 Makefile 文件</p>
<figure class="highlight makefile"><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><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br><span class="line">14</span><br><span class="line">15</span><br><span class="line">16</span><br><span class="line">17</span><br></pre></td><td class="code"><pre><span class="line">CC=arm-linux-gnueabihf-gcc</span><br><span class="line">CP=scp</span><br><span class="line">OUT_FILE=test</span><br><span class="line">OUT_PATH=pi:/home/pi/source/</span><br><span class="line"></span><br><span class="line"><span class="section">all: <span class="variable">$(OUT_FILE)</span></span></span><br><span class="line"></span><br><span class="line"><span class="section">%: %.c</span></span><br><span class="line"> <span class="variable">$(CC)</span> -o <span class="variable">$@</span> <span class="variable">$^</span></span><br><span class="line"></span><br><span class="line"><span class="meta"><span class="meta-keyword">.PHONY</span>: clean install</span></span><br><span class="line"></span><br><span class="line"><span class="section">clean:</span></span><br><span class="line"> <span class="variable">$(RM)</span> <span class="variable">$(OUT_FILE)</span></span><br><span class="line"></span><br><span class="line"><span class="section">install:</span></span><br><span class="line"> <span class="variable">$(CP)</span> <span class="variable">$(OUT_FILE)</span> <span class="variable">$(OUT_PATH)</span></span><br></pre></td></tr></table></figure>
