+Here is a short tutorial on how to build libftdi git under
+Ubuntu 12.10, But it is similar on other Linux distros.
+
+1) Install the build tools
+sudo apt-get install build-essential
+sudo apt-get install git-core
+sudo apt-get install cmake
+sudo apt-get install doxygen (for building documentations)
+
+2) Install dependencies
+sudo apt-get install libusb-1.0-devel
+(if the system comes with older version like 1.0.8 or
+earlier, it is recommended you build libusbx-1.0.14 or later).
+
+sudo apt-get install libconfuse-dev (for ftdi-eeprom)
+sudo apt-get install swig python-dev (for python bindings)
+sudo apt-get install libboost-all-dev (for C++ binding and unit test)
+
+3) Clone the git repository
+mkdir libftdi
+cd libftdi
+git clone git://developer.intra2net.com/libftdi
+
+If you are building the release tar ball, just extract the source
+tar ball.
+
+4) Build the git source and install
+cd libftdi
+mkdir build
+cd build
+cmake  -DCMAKE_INSTALL_PREFIX="/usr" ../
+make
+sudo make install
+
+5) carry out some tests
+cd examples
+
