FedoraCoin-Qt: Qt4 GUI for FedoraCoin
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 libminiupnpc-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
For Qt 5 you need the following, otherwise you get an error with lrelease when running qmake:
apt-get install qt5-qmake libqt5gui5 libqt5core5 libqt5dbus5 qttools5-dev-tools
then execute the following:
Alternatively, install Qt Creator and open the fedoracoin-qt.pro file.
An executable named fedoracoin-qt will be built.
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 either MacPorts or HomeBrew.
- Execute the following commands in a terminal to get the dependencies using MacPorts:
sudo port selfupdate sudo port install boost db48 miniupnpc
- Execute the following commands in a terminal to get the dependencies using HomeBrew:
brew update brew install boost miniupnpc openssl berkeley-db4
If using HomeBrew, edit fedoracoin-qt.pro to account for library location differences. There's a diff in contrib/homebrew/bitcoin-qt-pro.patch that shows what you need to change, or you can just patch by doing
patch -p1 < contrib/homebrew/bitcoin.qt.pro.patch
Open the fedoracoin-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 fedoracoin experience), pass the following argument to qmake:
(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:
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 FedoraCoin on a Linux/UNIX-ish system (tl;dr: Berkely DB databases are not forward compatible).
The static binary version of FedoraCoin 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 fedoracoin-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
