title: make ARCH=x86_64 CROSS_COMPILE ....... Error 2 while installing rtl8723de wifi drivers
body: <h2>I was trying to install rtl8712de wifi drivers in my Debian 10 PC.</h2>
  <p>I tried the following code:</p>
  <hr />
  <pre><code>sudo apt update
  git clone https://github.com/smlinux/rtl8723de.git
  cd rtl8723de
  make
  </code></pre>
  <hr />
  <p>After I ran the <code>make</code> command, I got the following error:</p>
  <pre><code>make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules//build M=/home/dantu/Downloads/rtl8723de  modules
  make[1]: *** /lib/modules//build: No such file or directory.  Stop.
  make: *** [Makefile:1886: modules] Error 2
  </code></pre>
  <hr />
  <p>I tried so many steps online. I installed gcc build tools, updated all my packages, tried other repositories for the wifi drivers. But nothing seems to help.</p>
