This guide will compile OpenOCD 0.5.0 for Ubuntu 10.04 with the FTD2XX driver library, for use with the TinCanTools Flyswatter.

Installing Packages

You will need to install several packages to compile and run OpenOCD. Open a terminal window (Applications menu > Accessories > Terminal) and type:

sudo apt-get install libtool
sudo apt-get install autoconf
sudo apt-get install texinfo
sudo apt-get install libusb-dev

If you prefer to compile libusb yourself, you can find the source at

Installing libFTD2XX

Download version 1.0.4 of the D2XX Linux drivers from Download page link is here: Extract the contents to your home directory (/home/USERNAME, replacing USERNAME with your username.)

In the terminal window, navigate to ~/libftd2xx1.0.4 and copy the files ftd2xx.h and WinTypes.h to /usr/local/include. Then navigate to /usr/include and create symbolic links to the header files.

cd ~/libftd2xx1.0.4
sudo cp ftd2xx.h /usr/include
sudo cp WinTypes.h /usr/include
cd /usr/local/include
sudo ln -s /usr/include/ftd2xx.h ftd2xx.h
sudo ln -s /usr/include/WinTypes.h WinTypes.h

Now return to the ~/libftd2xx1.0.4 directory and copy the library file to /usr/local/lib. The libftd2xx directory contains both 32-bit and 64-bit library files. If in doubt, use the 32-bit library file. To install the 32-bit library, copy the file located in /build/i386:

cd ~/libftd2xx1.0.4/build/i386
sudo cp /usr/local/lib

To install the 64-bit libraries, instead copy the file in /build/x86_64:

cd ~/libftd2xx/build/x86_64
sudo cp /usr/local/lib

Regardless of which you install, create symbolic links to the file in /usr/lib and /usr/local/lib. Name the links

cd /usr/local/lib
sudo ln -s
cd /usr/lib
sudo ln -s /usr/local/lib/

Downloading OpenOCD

Download the OpenOCD 0.5.0 source from and extract openocd-0.5.0 to your home directory (/home/USERNAME/openocd-0.5.0).

Patching OpenOCD

The OpenOCD Flyswatter2 beta patch provides support for the Flyswatter2 and updated config files for the original Flyswatter, the TinCanTools Hammer, and the Olimex PIC-P32MX board. Download the file Media:Tincantools-openocd-b0.12.patch. (Right click the link and select Save As.) Save the file to your new openocd-0.5.0 directory.

In the terminal window, navigate to the patch file and patch the source as follows:

cd ~/openocd-0.5.0
patch -p1 -i Tincantools-openocd-b0.12.patch

Even if you do not need Flyswatter2 support, you will need the updated config files in this patch to use the Flyswatter with OpenOCD-0.5.0. If you do not wish to install the patch you can download the config files individually from OpenOCD Config Files.

Compiling OpenOCD

In the terminal window, navigate to the new folder containing the OpenOCD source and compile as follows.

cd ~/openocd-0.5.0
sudo ./configure --disable-werror --enable-ft2232_ftd2xx --with-ftd2xx-linux-tardir="../libftd2xx1.0.4"
sudo make
sudo make install

Preparing to Run OpenOCD

Navigate to /home/USERNAME/openocd/src to find the openocd binary. You will need superuser priveleges to run OpenOCD.

You can run openocd from /home/USERNAME/openocd-0.5.0/src, but you may encounter problems with configuration files. For a more in-depth discussion of these issues, see OpenOCD Config File Paths. This guide recommends that you create a new directory containing OpenOCD and its config files.

Create a new directory in /home/USERNAME called openocd-bin, and copy the openocd binary and the contents of /home/USERNAME/openocd/tcl to the new directory. You can do this from the terminal window with the collowing commands:

cd ~
mkdir openocd-bin
cd ~/openocd-0.5.0/tcl
cp -r * ~/openocd-bin
cd ~/openocd-0.5.0/src
cp openocd ~/openocd-bin

openocd-bin should now contain the following files and subdirectories:


You can now run OpenOCD from /home/USERNAME/openocd-bin. To get started running OpenOCD, see Running OpenOCD on Linux.
