Compiling on the Raspberry PI is both extremely slow and an exercise in pain. Thankfully there are ways to cross compile the software using a standard desktop computer with the Raspberry PI as the target.
== Installing cross compiling toolchain ==
Run the following to install a newer cross compiling toolchain from your distro's package tree along with other necessary utilities:
<syntaxhighlight lang="text">apt-get install -y git bc bison flex rsync libssl-dev make device-tree-compiler libc6-dev libncurses5-dev crossbuild-essential-armhf crossbuild-essential-arm64</syntaxhighlight>
=== GCC 4.9 ===
If you intend to cross compile pieces of the Asterisk 1.4 distribution then you will need the GCC 4.9.x compiler. Linaro has a recent version of the GCC 4.9 compiler that we can use for this.
*Install latest GCC 4.9.x cross compiler and associated toolset:
