1 Bitcoin-qt: Qt4 based GUI replacement for Bitcoin
2 =================================================
4 **Warning** **Warning** **Warning**
6 Alpha version! I'm using this client myself on the production network, and I haven't noticed any glitches, but remember: always backup your wallet.
7 Testing on the testnet is recommended.
9 This has been implemented:
11 - qmake / QtCreator project (.pro)
13 - Compatibility with Linux (both GNOME and KDE), MacOSX and Windows
15 - All functionality of the original client, including taskbar icon/menu
19 - Overview page with current balance, unconfirmed balance, and such
21 - Better transaction list with status icons, real-time filtering and a context menu
23 - Asks for confirmation before sending coins, for your own safety
25 - CSV export of transactions and address book (for Excel bookkeeping)
27 - Shows alternative icon when connected to testnet, so you never accidentally send real coins during testing
29 - Shows a progress bar on initial block download, so that you don't have to wonder how many blocks it needs to download to be up to date
31 - Sendmany support, send to multiple recipients at the same time
33 - Multiple unit support, can show subdivided bitcoins (uBTC, mBTC) for users that like large numbers
35 - Support for English, German and Dutch languages
39 - Start at system start
41 - Support more languages
49 First, make sure that the required packages for Qt4 development of your
50 distribution are installed, for Debian and Ubuntu these are:
54 apt-get install qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev \
55 libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev \
56 libssl-dev libdb4.8++-dev
58 then execute the following:
65 Alternatively, install Qt Creator and open the `bitcoin-qt.pro` file.
67 An executable named `bitcoin-qt` will be built.
73 Windows build instructions:
75 - Download the `QT Windows SDK`_ and install it. You don't need the Symbian stuff, just the desktop Qt.
77 - Download and extract the `dependencies archive`_ [#]_, or compile openssl, boost and dbcxx yourself.
79 - 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.
81 - Open the .pro file in QT creator and build as normal (ctrl-B)

88 Berkely DB version warning
89 ==========================
91 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**).
93 The static binary version of Bitcoin is linked against libdb4.7 or libdb4.8 (see also `this Debian issue`_).
95 Now the nasty thing is that databases from 5.X are not compatible with 4.X.
97 If the globally installed development package of Berkely DB installed on your system is 5.X, any source you
98 build yourself will be linked against that. The first time you run with a 5.X version the database will be upgraded,
99 and 4.X cannot open the new format. This means that you cannot go back to the old statically linked version without
