WINDOWS BUILD NOTES
===================

Compilers Supported
-------------------
MinGW GCC  http://tdm-gcc.tdragon.net/
   TDM-GCC with gcc 4.5.1 was used to build this release.
MSYS 1.0.11 was also used (sh needed to compile some dependencies)


Candidate releases were built with MSVC 10.0 (2010), but
compiling with Visual C++ caused rendering artifacts when
bitcoin was run.


Dependencies
------------
Libraries you need to download separately and build:

                default path               download
wxWidgets       \wxwidgets-2.9.1-mgw       http://www.wxwidgets.org/downloads/
OpenSSL         \openssl-1.0.0c-mgw        http://www.openssl.org/source/
Berkeley DB     \db-4.7.25.NC-mgw          http://www.oracle.com/technology/software/products/berkeley-db/index.html
Boost           \boost-1.43.0-mgw          http://www.boost.org/users/download/
miniupnpc       \upnpc-exe-win32-20110215  http://miniupnp.tuxfamily.org/files/

Their licenses:
wxWidgets      LGPL 2.1 with very liberal exceptions
OpenSSL        Old BSD license with the problematic advertising requirement
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:
wxWidgets    2.9.1
OpenSSL      1.0.0c
Berkeley DB  4.7.25.NC
Boost        1.43.0
miniupnpc    1.5-20110215


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.

wxWidgets
---------
DOS shell:
cd \wxWidgets-2.9.1-mgw\build\msw
mingw32-make -f makefile.gcc

OpenSSL
-------
MSYS shell:
un-tar sources with MSYS 'tar xfz' to avoid issue with symlinks (OpenSSL ticket 2377)
change 'MAKE' env. variable from 'C:\MinGW32\bin\mingw32-make.exe' to '/c/MinGW32/bin/mingw32-make.exe'

cd /c/openssl-1.0.0c-mgw
./config
make

perl util/mkdef.pl 32 libeay enable-static-engine > libeay32.def
dllwrap --dllname libeay32.dll --output-lib libeay32.a --def libeay32.def libcrypto.a -lws2_32 -lgdi32

after that openssl libeay is in main source dir (openssl-1.0.0c-mgw)

Berkeley DB
-----------
MSYS shell:
cd /c/db-4.7.25.NC-mgw/build_unix
sh ../dist/configure --enable-mingw --enable-cxx
make


Boost
-----
DOS prompt:
downloaded boost jam 3.1.18
cd \boost-1.43.0-mgw
bjam toolset=gcc --build-type=complete stage

Note:
building with boost 1.45.0 failed because of boost ticket 4614, 4258
builds fine with boost 1.43.0

MiniUPnPc
---------
Building miniupnpc failed on Windows Server 2003, thus it is expected that a binary copy will be used.
See http://miniupnp.tuxfamily.org/forum/viewtopic.php?t=642
UPnP support is optional, make with USE_UPNP= to disable it.

Get upnpc-exe-win32-20110215.zip and unzip it to \upnpc-exe-win32-20110215
Get miniupnpc-1.5.20110215.tar.gz and copy *.h to \upnpc-exe-win32-20110215\miniupnpc

Bitcoin
-------
DOS prompt:
cd \bitcoin
mingw32-make bitcoin.exe bitcoind.exe -f makefile.mingw
strip bitcoin.exe
strip bitcoind.exe
