zlib is a compression library and a prerequisite for building GLib.
Download, cross compile and install the zlib compression libraries. Configure doesn't accept the --host parameter (reports unknown option), so you need to hack the makefile.
wget http://zlib.net/zlib-1.2.8.tar.gz tar -xzf zlib-1.2.8.tar.gz cd zlib-1.2.8/ ./configure --prefix=/usr/arm-linux-gnueabi
Edit the makefile and prefix the build tools with arm-linux-gnueabi-.
CC=arm-linux-gnueabi-gcc LDSHARED=arm-linux-gnueabi-gcc -shared -Wl,-soname,libz.so.1,--version-script,zlib.map CPP=arm-linux-gnueabi-gcc -E AR=arm-linux-gnueabi-ar RANLIB=arm-linux-gnueabi-ranlib
Make and install:
make make install
libffi is the Portable Foreign Function Interface Library and is a prerequisite for building GLib. It is an interface that allows code written in one language to call code written in another language.
Download, build and install:
wget ftp://sourceware.org/pub/libffi/libffi-3.0.13.tar.gz tar -xzf libffi-3.0.13.tar.gz cd libffi-3.0.13/ ./configure --host=arm-linux-gnueabi --prefix=/usr/arm-linux-gnueabi make make install
GLib is part of the GTK+ Project
GLib requires zlib, libffi and glibc >= 2.18 to successfully build. If you are building on ubuntu 14.04, the arm-linux-gnueabi should come installed with glibc 2.19 hence we don't rebuild it.
GLib requires the glib-genmarshal tool installed on your build system otherwise the following error is likey to result:
checking for glib-genmarshal... no configure: error: Could not find a glib-genmarshal in your PATH
An easy way to resolve this is to install libglib2.0-dev:
sudo apt-get install libglib2.0-dev
To build Glib, download, build and install:
wget http://ftp.gnome.org/pub/gnome/sources/glib/2.40/glib-2.40.0.tar.xz tar -xJf glib-2.40.0.tar.xz cd glib-2.40.0 ./configure --host=arm-linux-gnueabi --prefix=/usr/arm-linux-gnueabi PKG_CONFIG_PATH=/usr/arm-linux-gnueabi/lib/pkgconfig glib_cv_stack_grows=no glib_cv_uscore=yes ac_cv_func_posix_getpwuid_r=yes ac_cv_func_posix_getgrgid_r=yes make make install
Expat is an XML parser library written in C and is the only required dependency for the D-Bus daemon.
Download, build and install:
wget http://sourceforge.net/projects/expat/files/expat/2.1.0/expat-2.1.0.tar.gz tar -xzf expat-2.1.0.tar.gz cd expat-2.1.0/ ./configure --host=arm-linux-gnueabi --prefix=/usr/arm-linux-gnueabi make make install
D-Bus is a message bus system. It requires the expat library to successfully build otherwise the following error may result:
checking for XML_ParserCreate_MM in -lexpat... no configure: error: Explicitly requested expat but expat not found
Download, build and install:
wget http://dbus.freedesktop.org/releases/dbus/dbus-1.8.0.tar.gz tar -xzf dbus-1.8.0.tar.gz cd dbus-1.8.0/ ./configure --host=arm-linux-gnueabi --prefix=/usr/arm-linux-gnueabi make make install make install DESTDIR=/home/export/rootfs
libical provides a library for the iCal standard. It is a prerequisite of BlueZ.
libical requires cmake and g++ cross compilers to be installed:
sudo apt-get install cmake sudo apt-get install g++-arm-linux-gnueabi
Download, build and install the library:
wget http://downloads.sourceforge.net/freeassociation/libical-1.0.tar.gz tar -xzf libical-1.0.tar.gz cd libical-1.0/ export CC=arm-linux-gnueabi-gcc export CXX=arm-linux-gnueabi-g++ cmake -DCMAKE_INSTALL_PREFIX=/usr/arm-linux-gnueabi make make install
Readline references functions in ncurses. If ncurses is not linked, the following errors are likely to result when building BlueZ:
/usr/arm-linux-gnueabi/lib/libreadline.so: undefined reference to `PC' /usr/arm-linux-gnueabi/lib/libreadline.so: undefined reference to `tgetflag' /usr/arm-linux-gnueabi/lib/libreadline.so: undefined reference to `tgetent' /usr/arm-linux-gnueabi/lib/libreadline.so: undefined reference to `UP' /usr/arm-linux-gnueabi/lib/libreadline.so: undefined reference to `tputs' /usr/arm-linux-gnueabi/lib/libreadline.so: undefined reference to `tgoto' /usr/arm-linux-gnueabi/lib/libreadline.so: undefined reference to `tgetnum' /usr/arm-linux-gnueabi/lib/libreadline.so: undefined reference to `BC' /usr/arm-linux-gnueabi/lib/libreadline.so: undefined reference to `tgetstr'
First we must build ncurses and then link it to Readline using SHLIB_LIBS=-lncurses.
Download, build and install the ncurses library:
wget http://ftp.gnu.org/pub/gnu/ncurses/ncurses-5.9.tar.gz 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 make install
Download, build and install the readline library:
wget ftp://ftp.cwru.edu/pub/bash/readline-6.3.tar.gz tar -xzf readline-6.3.tar.gz cd readline-6.3/ ./configure --host=arm-linux-gnueabi --prefix=/usr/arm-linux-gnueabi bash_cv_wcwidth_broken=yes make SHLIB_LIBS=-lncurses make install
The bash_cv_wcwidth_broken=yes parameter avoids the following error when cross-compiling:
checking for wcwidth broken with unicode combining characters... configure: error: in `/.../readline-6.3': configure: error: cannot run test program while cross compiling
BlueZ is the official Bluetooth protocol stack for Linux and include tools such as hciattach, hciconfig, hcitool and rfcomm.
BlueZ 5.18 requires GLib >= 2.28, D-Bus >= 1.6 and libudev >= 143. When these prerequisites are meet, you can download, build and install BlueZ using:
wget http://www.kernel.org/pub/linux/bluetooth/bluez-5.18.tar.xz tar -xJf bluez-5.18.tar.xz cd bluez-5.18 ./configure --host=arm-linux-gnueabi --prefix= PKG_CONFIG_PATH=/usr/arm-linux-gnueabi/lib/pkgconfig --disable-systemd --disable-udev --disable-cups --disable-obex --enable-library make make install DESTDIR=/usr/arm-linux-gnueabi make install DESTDIR=/home/export/rootfs
Some of the BlueZ tools (e.g. sdptool requires libglib, bluetoothd requires libdbus-1, dbus-daemon requires libexpat, bluetoothctl requires libreadline) will require the following shared libraries installed:
cp /usr/arm-linux-gnueabi/lib/libglib-2.0.so.0.4000.0 /home/export/rootfs/lib cp /usr/arm-linux-gnueabi/lib/libdbus-1.so.3.8.3 /home/export/rootfs/lib cp /usr/arm-linux-gnueabi/lib/libexpat.so.1.6.0 /home/export/rootfs/lib cp /usr/arm-linux-gnueabi/lib/libreadline.so.6.3 /home/export/rootfs/lib
The Bluetooth Daemon requires the D-Bus Daemon to be running, otherwise the following error will result:
D-Bus setup failed: Failed to connect to socket /usr/arm-linux-gnueabi/var/run/dbus/system_bus_socket: No such file or directory
Copy the default bluetooth.conf over to dbus-1/systemd.d on the target:
cp bluez-5.18/src/bluetooth.conf /home/export/rootfs/etc/dbus-1/system.d/
The D-Bus Daemon wants to spawn from the user/group messagebus/messagebus. Failure to create a user and group results with:
Failed to start message bus: Could not get UID and GID for username "messagebus"
Create the appropriate group and user account:
addgroup -S messagebus adduser -S messagebus -G messagebus
Now start the D-Bus Daemon:
dbus-daemon --system
Finally, start the Bluetooth Daemon:
/libexec/bluetooth/bluetoothd
The hciconfig (BlueTooth Host Controller Interface Configuration utility) will show any BlueTooth host controllers present:
# hciconfig

You can bring up the interface by issuing:

Now you can scan for BlueTooth devices:
# hcitool -i hci0 scan
