TulipCoin development tree
TulipCoin is a PoS-based cryptocurrency.
Developers work in their own trees, then submit pull requests when they think their feature or bug fix is ready.
The patch will be accepted if there is broad consensus that it is a good thing. Developers should expect to rework and resubmit patches if they don't match the project's coding conventions (see coding.txt) or are controversial.
The master branch is regularly built and tested, but is not guaranteed to be completely stable. Tags are regularly created to indicate new stable release versions of TulipCoin.
Feature branches are created when there are major new features being worked on by several people.
From time to time a pull request will become outdated. If this occurs, and the pull is no longer automatically mergeable; a comment on the pull will be used to issue a warning of closure. The pull will be closed 15 days after the warning if action is not taken by the author. Pull requests closed in this manner will have their corresponding issue labeled 'stagnant'.
Issues with no commits will be given a similar warning, and closed after 15 days from their last activity. Issues closed in this manner will be labeled 'stale'.
TulipCoin-qt: Qt5 GUI for TulipCoin
Build instructions
Debian
First, make sure that the required packages for Qt5 development of your distribution are installed, for Debian and Ubuntu these are:
apt-get install qt5-default qt5-qmake qtbase5-dev-tools qttools5-dev-tools
build-essential libboost-dev libboost-system-dev
libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev
libssl-dev libdb++-dev
This Step is needed as well sudo apt-get install libqt4-dev libminiupnpc-dev then execute the following:
qmake make Alternatively, install Qt Creator and open the tulipcoin-qt.pro file.
An executable named tulipcoin-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. Compile openssl, boost and dbcxx. Open the .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 .pro file in Qt Creator and build as normal (cmd-B) Build configuration options
UPNnP port forwarding
To use UPnP for port forwarding behind a NAT router (recommended, as more connections overall allow for a faster and more stable tulipcoin 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 TulipCoin on a Linux/UNIX-ish system (tl;dr: Berkely DB databases are not forward compatible).
The static binary version of TulipCoin is linked against libdb 5.0 (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 tulipcoin-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
