<span class="mw-headline">In order to compile the Linux Kernel it is necessary to prepare a suitable work environment by checking the compiler and its version are the corresponding. </span> <span class="mw-headline">In this case the Linux Kernel {{Message/Information Message|message=The following steps has been compiled tested using an '''''Ubuntu 16.04''''' and the compiler '''''gcc version 4.9.3 (Ubuntu/Linaro 4.9.3-13ubuntu2)'''''.}}</span>
<span class="mw-headline">If we want to install a particular compiler, for example the 4.9 we can use the following commands to install it:<br /></span>
<pre class="minicom"><code> <span class="mw-headline"><code>g++-4.9-arm-linux-gnueabihf<br data-attributes="%20/">cpp-4.9-arm-linux-gnueabihf<br data-attributes="%20/">gcc-4.9-arm-linux-gnueabihf<br data-attributes="%20/">gcc-4.9-arm-linux-gnueabihf-base</span></code><span class="mw-headline"><br></span></pre>
<span class="mw-headline">We can change between compilers using the following commands:</span>
