1 Novacoin-qt: Qt4 GUI for Novacoin
2 ===============================
10 First, make sure that the required packages for Qt4 development of your
11 distribution are installed, these are
15 for Debian and Ubuntu <= 11.10 :
19 sudo apt-get install qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev \
20 libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev \
21 libssl-dev libdb4.8++-dev
23 for Ubuntu >= 12.04 (please read the 'Berkely DB version warning' below):
27 sudo apt-get install qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev \
28 libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev \
29 libssl-dev libdb++-dev
35 sudo apt-get install git
37 clone the repository :
41 git clone https://github.com/novacoin-project/novacoin
44 Execute the following:
49 qmake USE_O3=1 USE_ASM=1 RELEASE=1
52 Alternatively, install Qt Creator and open the `novacoin-qt.pro` file.
54 An executable named `novacoin-qt` will be built.
56 To build novacoind execute the following:
61 make -f makefile.unix USE_O3=1 USE_ASM=1 STATIC=1
68 Windows build instructions:
70 - Download the `QT Windows SDK`_ and install it. You don't need the Symbian stuff, just the desktop Qt.
72 - Download and extract the `dependencies archive`_ [#]_, or compile openssl, boost and dbcxx yourself.
74 - 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.
76 - Open the .pro file in QT creator and build as normal (ctrl-B)

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

104 Build configuration options
105 ============================
107 LevelDB transaction index
108 --------------------------
110 To use LevelDB for transaction index, pass the following argument to qmake:
114 qmake "USE_LEVELDB=1"
116 No additional external dependencies are required. If you're running this on your current sources tree then don't forget to run
122 prior to running qmake.
124 Assembler implementation of scrypt hashing
125 ------------------------------------------
127 To use optimized scrypt implementation instead of generic scrypt module, pass the following argument to qmake:
134 If you're using clang compiler then you need to unroll macroses before compiling. Following commands will do this for you:
139 ../contrib/clang/nomacro.pl
141 No additional external dependencies required. Note that only x86, x86_64 and ARM processors are supported.
143 Notification support for recent (k)ubuntu versions
144 ---------------------------------------------------
146 To see desktop notifications on (k)ubuntu versions starting from 10.04, enable usage of the
147 FreeDesktop notification interface through DBUS using the following qmake option:
153 Generation of QR codes
154 -----------------------
156 libqrencode is used to generate QRCode images for payment requests.
157 It can be downloaded from http://fukuchi.org/works/qrencode/index.html.en, or installed via your package manager.
159 Berkely DB version warning
160 ==========================
162 A warning for people using the *static binary* version of Novacoin on a Linux/UNIX-ish system (tl;dr: **Berkely DB databases are not forward compatible**).
164 The static binary version of Novacoin is linked against libdb5.3.
166 If the globally installed development package of Berkely DB installed on your system is 5.X, for example, any source you
167 build yourself will be linked against that. The first time you run with a 5.X version the database will be upgraded,
168 and 4.X cannot open the new format. This means that you cannot go back to the old statically linked version without
174 Ubuntu 11.10 has a package called 'qt-at-spi' installed by default. At the time of writing, having that package
175 installed causes novacoin-qt to crash intermittently. The issue has been reported as `launchpad bug 857790`_, but
178 Until the bug is fixed, you can remove the qt-at-spi package to work around the problem, though this will presumably
179 disable screen reader functionality for Qt apps:
183 sudo apt-get remove qt-at-spi
