Download, build and install the ncurses library:

tar -xzf ncurses-5.9.tar.gz
cd ncurses-5.9
./configure --host=arm-linux-gnueabi --prefix=/usr/arm-linux-gnueabi CXX="arm-linux-gnueabi-g++"
make install


SQLite is a software library that implements a self contained server-less transactional SQL database engine.

tar -xzf sqlite-autoconf-3080500.tar.gz
cd sqlite-autoconf-3080500
./configure --host=arm-linux-gnueabi --prefix=/usr/arm-linux-gnueabi 
make install 


Certain Asterisk modules such as chan_sip and chan_iax2 require the res_crypto resource module. The res_crypto module will only be built if the libssl dependency is installed.

tar -xzf openssl-1.0.1h.tar.gz
cd openssl-1.0.1h
./Configure linux-generic32 shared --prefix=/usr/arm-linux-gnueabi
make CC=arm-linux-gnueabi-gcc RANLIB=arm-linux-gnueabi-ranlib LD=arm-linux-gnueabi-ld MAKEDEPPROG=arm-linux-gnueabi-gcc
make install CC=arm-linux-gnueabi-gcc RANLIB=arm-linux-gnueabi-ranlib LD=arm-linux-gnueabi-ld

BlueZ Bluetooth Libraries (Optional)

If you want to use chan_mobile to connect asterisk to your mobile phone via Bluetooth, then you will require the Bluetooth libraries and header files installed at this point.

See Cross Compiling BlueZ Bluetooth tools for ARM


With all our prerequisites built, you can now download, build and install Asterisk:

tar -xzf asterisk-11.11.0.tar.gz
cd asterisk-11.11.0
./configure --host=arm-linux-gnueabi --target=arm-linux-gnueabi --build=i686-pc-linux-gnu --disable-xmldoc
make menuselect
sudo make install DESTDIR=/home/export/rootfs
sudo make samples DESTDIR=/home/export/rootfs

Asterisk will require shared libraries to load. Copy over,, and to your root filesystem:

cp /usr/arm-linux-gnueabi/lib/ /home/export/rootfs/lib
cp /usr/arm-linux-gnueabi/lib/ /home/export/rootfs/lib
cp /usr/arm-linux-gnueabi/lib/ /home/export/rootfs/lib
cp /usr/arm-linux-gnueabi/lib/ /home/export/rootfs/lib
cp /usr/lib/gcc-cross/arm-linux-gnueabi/4.7.3/ /home/export/rootfs/lib

And if you are using chan_mobile (Bluetooth):

cp /usr/arm-linux-gnueabi/lib/ /home/export/rootfs/lib

In addition to the above new libraries, Asterisk also places in /usr/lib. If ldconfig is not executed to re-configure dynamic linker run-time bindings, Asterisk is likely to generate an error: error while loading shared libraries: cannot open shared object file: No such file or directory.

To generate new dynamic linker run-time bindings, on the actual host, execute:

ldconfig -v

Outside of modifying Asterisk configuration files, Asterisk should now we ready to run. To start with a console CLI:

asterisk -c
