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.
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.
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
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 make make install
