Bitcoin is a free open source peer-to-peer electronic cash system that is completely decentralized, without the need for a central server or trusted parties. Users hold the crypto keys to their own money and transact directly with each other, with the help of a P2P network to check for double-spending.

Build instructions

Debian, Ubuntu, Mint

Install Qt Creator.

Install libminiupnpc-dev.

Make sure that the required packages for Qt4 development of your distribution are installed, for Debian and Ubuntu these are:

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

then execute the following:

qmake
make

Alternatively, use Qt Creator and open the bitcoin-qt.pro file.

An executable named fairbrix-qt will be built.

Windows

see https://bitcointalk.org/index.php?topic=149479.0 ("Building headless Bitcoin and Bitcoin-qt on Windows")

• "Qt 4.8.5 command prompt" means: run C:\Qt\4.8.5\bin\qtvars.bat from Windows command prompt (as administrator)

• Steps 3.2 and 4.2 are already done.

• An executable (in the \release folder) will be built.

Notes:

• You will also need to distribute mingwm10.dll along with the executable(s).
• Only use libgcc_s_dw2-1.dll, libstdc++-6.dll and mingwm10.dll from C:\MinGW\bin folder, and QtCore4.dll, QtGui4.dll and QtNetwork4.dll from C:\Qt\4.8.5\bin folder. (DLLs with same name from other folders crash the executable)
• Keep Qt 4.8.5 installed. (optional but recommended)
