UNIX BUILD NOTES
================

To Build
--------

cd src/

make -f makefile.unix            # Bitcoin with wxWidgets GUI
  or
make -f makefile.unix bitcoind   # Headless bitcoin


Dependencies
------------
sudo apt-get install build-essential
sudo apt-get install libgtk2.0-dev
sudo apt-get install libssl-dev
sudo apt-get install libdb4.8-dev
sudo apt-get install libdb4.8++-dev
Boost 1.40+: sudo apt-get install libboost-all-dev
or Boost 1.37: sudo apt-get install libboost1.37-dev

If using Boost 1.37, append -mt to the boost libraries in the makefile.

Requires wxWidgets 2.9.0 or greater, which uses UTF-8.  Don't try 2.8, it
won't work.

You need to download wxWidgets from http://www.wxwidgets.org/downloads/
and build it yourself.  See the build instructions and configure parameters
below.

Requires miniupnpc for UPnP port mapping.  It can be downloaded from
http://miniupnp.tuxfamily.org/files/.  UPnP support is compiled in and
turned off by default.  Set USE_UPNP to a different value to control this:
USE_UPNP=   no UPnP support, miniupnp not required;
USE_UPNP=0  (the default) UPnP support turned off by default at runtime;
USE_UPNP=1  UPnP support turned on by default at runtime.

Licenses of statically linked libraries:
wxWidgets      LGPL 2.1 with very liberal exceptions
Berkeley DB    New BSD license with additional requirement that linked software must be free open source
Boost          MIT-like license
miniupnpc      New (3-clause) BSD license

Versions used in this release:
GCC          4.3.3
OpenSSL      0.9.8g
wxWidgets    2.9.2
Berkeley DB  4.8.30.NC
Boost        1.37
miniupnpc    1.6


Notes
-----
The UI layout is edited with wxFormBuilder.  The project file is
uiproject.fbp.  It generates uibase.cpp and uibase.h, which define base
classes that do the rote work of constructing all the UI elements.

The release is built with GCC and then "strip bitcoin" to strip the debug
symbols, which reduces the executable size by about 90%.


wxWidgets
---------
cd /usr/local
tar -xzvf wxWidgets-2.9.2.tar.gz
cd wxWidgets-2.9.2
mkdir buildgtk
cd buildgtk
../configure --with-gtk --enable-debug --disable-shared --enable-monolithic --without-libpng --disable-svg
make
sudo su
make install
ldconfig


miniupnpc
---------
tar -xzvf miniupnpc-1.6.tar.gz
cd miniupnpc-1.6
make
sudo su
make install


Berkeley DB
-----------
You need Berkeley DB 4.8.  If you have to build Berkeley DB yourself:
../dist/configure --enable-cxx
make


Boost
-----
If you need to build Boost yourself:
sudo su
./bootstrap.sh
./bjam install
