Bitcoin-Qt: Qt4 GUI for Bitcoin

Build instructions

Debian

First, make sure that the required packages for Qt4 development of your distribution are installed, for Debian and Ubuntu these are:

apt-get install qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev \
    libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev \
    libssl-dev libdb4.8++-dev

then execute the following:

qmake
make

Alternatively, install Qt Creator and open the bitcoin-qt.pro file.

An executable named bitcoin-qt will be built.

Windows

Windows build instructions:

  • Download the Qt Windows SDK and install it. You don't need the Symbian stuff, just the desktop Qt.
  • Download and extract the dependencies archive1, or compile openssl, boost and dbcxx yourself.
  • Copy the contents of the folder "deps" to "X:\QtSDK\mingw", replace X:\ with the location where you installed the Qt SDK. Make sure that the contents of "deps\include" end up in the current "include" directory.
  • Open the bitcoin-qt.pro file in Qt Creator and build as normal (ctrl-B)

Mac OS X

  • Download and install the Qt Mac OS X SDK. It is recommended to also install Apple's Xcode with UNIX tools.
  • Download and install MacPorts.
  • Execute the following commands in a terminal to get the dependencies:
sudo port selfupdate
sudo port install boost db48 miniupnpc
  • Open the bitcoin-qt.pro file in Qt Creator and build as normal (cmd-B)

Build configuration options

UPnP port forwarding

To use UPnP for port forwarding behind a NAT router (recommended, as more connections overall allow for a faster and more stable bitcoin experience), pass the following argument to qmake:

qmake "USE_UPNP=1"

(in Qt Creator, you can find the setting for additional qmake arguments under "Projects" -> "Build Settings" -> "Build Steps", then click "Details" next to qmake)

This requires miniupnpc for UPnP port mapping. It can be downloaded from http://miniupnp.tuxfamily.org/files/. UPnP support is not compiled in by default.

Set USE_UPNP to a different value to control this:

USE_UPNP=- no UPnP support, miniupnpc not required;
USE_UPNP=0 (the default) built with UPnP, support turned off by default at runtime;
USE_UPNP=1 build with UPnP support turned on by default at runtime.

Notification support for recent (k)ubuntu versions

To see desktop notifications on (k)ubuntu versions starting from 10.04, enable usage of the FreeDesktop notification interface through DBUS using the following qmake option:

qmake "USE_DBUS=1"

Generation of QR codes

libqrencode may be used to generate QRCode images for payment requests. It can be downloaded from http://fukuchi.org/works/qrencode/index.html.en, or installed via your package manager. Pass the USE_QRCODE flag to qmake to control this:

USE_QRCODE=0 (the default) No QRCode support - libarcode not required
USE_QRCODE=1 QRCode support enabled

Berkely DB version warning

A warning for people using the static binary version of Bitcoin on a Linux/UNIX-ish system (tl;dr: Berkely DB databases are not forward compatible).

The static binary version of Bitcoin is linked against libdb4.8 (see also this Debian issue).

Now the nasty thing is that databases from 5.X are not compatible with 4.X.

If the globally installed development package of Berkely DB installed on your system is 5.X, any source you build yourself will be linked against that. The first time you run with a 5.X version the database will be upgraded, and 4.X cannot open the new format. This means that you cannot go back to the old statically linked version without significant hassle!

Ubuntu 11.10 warning

Ubuntu 11.10 has a package called 'qt-at-spi' installed by default. At the time of writing, having that package installed causes bitcoin-qt to crash intermittently. The issue has been reported as launchpad bug 857790, but isn't yet fixed.

Until the bug is fixed, you can remove the qt-at-spi package to work around the problem, though this will presumably disable screen reader functionality for Qt apps:

sudo apt-get remove qt-at-spi
