Bitcoin-Qt: Qt4 GUI for Bitcoin
|
|
===============================
|
|
|
|
Build instructions
|
|
===================
|
|
|
|
Debian
|
|
-------
|
|
|
|
First, make sure that the required packages for Qt4 development of your
|
|
distribution are installed, these are
|
|
|
|
::
|
|
|
|
for Debian and Ubuntu <= 11.10 :
|
|
|
|
::
|
|
|
|
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
|
|
|
|
for Ubuntu >= 12.04 (please read the 'Berkely DB version warning' below):
|
|
|
|
::
|
|
|
|
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 libdb++-dev libminiupnpc-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.
|
|
|
|
.. _`Qt Creator`: http://qt-project.org/downloads/
|
|
|
|
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)
|
|
|
|
.. _`Qt Mac OS X SDK`: http://qt-project.org/downloads/
|
|
.. _`MacPorts`: http://www.macports.org/install.php
|
|
|
|
|
|
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
|
|
|
|
.. _`launchpad bug 857790`: https://bugs.launchpad.net/ubuntu/+source/qt-at-spi/+bug/857790
