====== Compile Accel-ppp on OpenWrt ======
===== Getting the code =====
  * This page contains the instructions for compiling Accel-ppp on OpenWrt version 23.05.x
  * We assume you have already checked out the OpenWrt SDK.
  * You can find more details here: https://www.radiusdesk.com/wiki/technical/openwrt-prep.
  * Make sure you include install the packages needed for Accel-ppp.
<code bash>
#Do this under the openwrt directory 
cd openwrt
./scripts/feeds install libpcre 
./scripts/feeds install libopenssl 
./scripts/feeds install libpthread 
./scripts/feeds install librt 
./scripts/feeds install libatomic 
./scripts/feeds install libucontext 
./scripts/feeds install kmod-sched-core 
./scripts/feeds install kmod-pptp 
./scripts/feeds install kmod-pppoe 
./scripts/feeds install kmod-ppp
</code>
  * The Accel-ppp package is part of the MESHdesk code:
<code bash>
#Do this in the working directory e.g. cd 23.05.0 (on the same level as the openwrt directory)
git clone https://github.com/RADIUSdesk/openwrt-meshdesk.git openwrt-meshdesk
</code>
===== Adding the package =====
  * The **openwrt-accel-ppp** folder needs to be copied under the package folder (openwrt/package).
<code bash>
#cd to the working directory
cp -R ./openwrt-meshdesk/openwrt-accel-ppp ./openwrt/package 
</code>
===== Selecting the package =====
  * The package will be listed under **Network**.
  * You can select it and run **make** to build the firmware.

===== Ensuring smooth startup =====
  * When we include Accel-ppp along with the MESHdesk package we do an initial prep before calling the start-up script.
  * See the code below as reference
<code lua>
function rdAccel.__prepAccel(self)
   os.execute('/etc/init.d/accel-ppp disable');
   os.execute('mkdir /var/log/accel-ppp');
   os.execute('ln -s /usr/lib/accel-ppp/libconnlimit.so /usr/lib');
   os.execute('ln -s /usr/lib/accel-ppp/libvlan-mon.so  /usr/lib');
   os.execute('ln -s /usr/lib/accel-ppp/libradius.so   /usr/lib');
end
