Building headless Bitcoin and Bitcoin-qt on Windows

Windows MSYS/MINGW build instructions transcribed from bitcointalk 2015-02-08

“So what i think I need is a guide to show me how to static-build GapMiner.”

One option is to remove the -march=native switch when compiling dynamically. The resultant binary should be system independent.

Otherwise, you’ll need to compile all the dependent libraries for Windows: boost, gmp, mpfr, openssl, curl and then link it together.

https://bitcointalk.org/index.php?topic=149479.0 (see below) should be a good starting point, for Linux you have to change some of the config parameters.

Alternatively, it may be possible to install some of those libraries as binaries within the MINGW environment.

A Makefile to compile GapMiner with all libraries linked statically would look like this:

SRC       = ./src
BIN       = ./bin
CC        = g++
CXXFLAGS = -O3 -c -lm -pthread \

Building headless Bitcoin and Bitcoin-qt on Windows 2013-03-05

Hi all, I recently went through the process of building bitcoind on windows.

I found the official build-msw.txt to be a bit lacking, so I thought that documenting the steps here on the forums could save some time to people wanting to compile their own windows binary.

Please note this is mostly for testing purposes. Always use official executables on production environments.

The following instructions are intended for use with version 0.9.4. See additional notes if compiling 0.10rc4 or an older 0.8.6 branch.

1. Prepare your build system.

I strongly suggest setting up a clean windows virtual machine via Virtualbox or similar.

1.1 Install msys shell:

http://sourceforge.net/projects/mingw/files/Installer/mingw-get-setup.exe/download

From MinGW installation manager -> All packages -> MSYS mark the following for installation:

msys-base-bin
msys-autoconf-bin
msys-automake-bin
msys-libtool-bin

then click on Installation -> Apply changes

Make sure no mingw packages are checked for installation or present from a previous install. Only the above msys packages should be installed. Also make sure that msys-gcc and msys-w32api packages are not installed.

1.2 Install MinGW-builds project toolchain:

Download http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/mingw-builds/4.9.2/threads-posix/dwarf/i686-4.9.2-release-posix-dwarf-rt_v3-rev1.7z/download and unpack it to C:\

1.3. Ensure that mingw-builds bin folder is set in your PATH environment variable.

On Windows 7 your path should look something like:

C:\mingw32\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\

1.4 Additional checks:

C:\MinGW\bin should contain nothing but mingw-get.exe.

Your gcc -v output should be:

$ gcc -v
Using built-in specs.
COLLECT_GCC=c:\mingw32\bin\gcc.exe
COLLECT_LTO_WRAPPER=c:/mingw32/bin/../libexec/gcc/i686-w64-mingw32/4.9.2/lto-wrapper.exe

2. Download, unpack and build required dependencies.

I’ll save them in C:\deps folder.

OpenSSL

From a MinGw shell (C:\MinGW\msys\1.0\msys.bat), unpack the source archive with tar (this will avoid symlink issues) then configure and make:

cd /c/deps/
tar xvfz openssl-1.0.1l.tar.gz
cd openssl-1.0.1l
./Configure no-zlib no-shared no-dso no-krb5 no-camellia no-capieng no-cast \
no-cms no-dtls1 no-gost no-gmp no-heartbeats no-idea no-jpake no-md2 no-mdc2 \
no-rc5 no-rdrand no-rfc3779 no-rsax no-sctp no-seed no-sha0 no-static_engine \
no-whirlpool no-rc2 no-rc4 no-ssl2 no-ssl3 mingw
make

2.2 Berkeley DB

We’ll use version 4.8 to preserve binary wallet compatibility. From a MinGW shell unpack the source archive, configure and make:

cd /c/deps/
tar xvfz db-4.8.30.NC.tar.gz
cd db-4.8.30.NC/build_unix
../dist/configure --enable-mingw --enable-cxx --disable-shared --disable-replication
make

2.3 Boost

Download either the zip or the 7z archive, unpack boost inside your C:\deps folder, then bootstrap and compile from a Windows command prompt:

cd C:\deps\boost_1_57_0\
bootstrap.bat mingw
b2 --build-type=complete --with-chrono --with-filesystem --with-program_options \
--with-system --with-thread toolset=gcc variant=release link=static threading=multi \
runtime-link=static stage

This will compile the required boost libraries and put them into the stage folder (C:\deps\boost_1_57_0\stage). Note: make sure you don’t use tarballs, as unix EOL markers can break batch files.

2.4 Miniupnpc

Unpack Miniupnpc to C:\deps, rename containing folder from “miniupnpc-1.9.20150206” to “miniupnpc” then from a Windows command prompt:

cd C:\deps\miniupnpc
mingw32-make -f Makefile.mingw init upnpc-static

2.5 protoc and libprotobuf

From msys shell

tar xvfz protobuf-2.6.1.tar.gz
cd /c/deps/protobuf-2.6.1
configure --disable-shared
make

2.6 qrencode

Download and unpack libpng inside your C:\deps folder then configure and make:

cd /c/deps/libpng-1.6.16
configure --disable-shared
make
cp .libs/libpng16.a .libs/libpng.a

Download and unpack qrencode inside your C:\deps folder then configure and make:

cd /c/deps/qrencode-3.4.4

LIBS="../libpng-1.6.16/.libs/libpng.a ../../mingw32/i686-w64-mingw32/lib/libz.a" \
png_CFLAGS="-I../libpng-1.6.16" \
png_LIBS="-L../libpng-1.6.16/.libs" \
configure --enable-static --disable-shared --without-tools

make

2.7 Qt 5 libraries:

Qt must be configured with ssl and zlib support.

Download and unpack Qt base and Qt tools sources:

Then from a windows command prompt (note that the following assumes qtbase has been unpacked to C:\Qt\5.3.2 and qttools have been unpacked to C:\Qt\qttools-opensource-src-5.3.2):

set INCLUDE=C:\deps\libpng-1.6.16;C:\deps\openssl-1.0.1l\include
set LIB=C:\deps\libpng-1.6.16\.libs;C:\deps\openssl-1.0.1l

cd C:\Qt\5.3.2
configure.bat -release -opensource -confirm-license -static -make libs -no-sql-sqlite \
-no-opengl -system-zlib -qt-pcre -no-icu -no-gif -system-libpng -no-libjpeg -no-freetype \
-no-angle -no-vcproj -openssl -no-dbus -no-audio-backend -no-wmf-backend -no-qml-debug

mingw32-make

set PATH=%PATH%;C:\Qt\5.3.2\bin

cd C:\Qt\qttools-opensource-src-5.3.2
qmake qttools.pro
mingw32-make

Note: consider using -j switch with mingw32-make to speed up compilation process. On a quad core -j4 or -j5 should give the best results.

3. Bitcoin 0.9.4

Download and unpack [Bitcoin 0.9.4(https://github.com/bitcoin/bitcoin/archive/v0.9.4.zip) from git

From msys shell configure and make bitcoin:

cd /c/bitcoin-0.9.4

./autogen.sh

CPPFLAGS="-I/c/deps/db-4.8.30.NC/build_unix \
-I/c/deps/openssl-1.0.1l/include \
-I/c/deps \
-I/c/deps/protobuf-2.6.1/src \
-I/c/deps/libpng-1.6.16 \
-I/c/deps/qrencode-3.4.4" \
LDFLAGS="-L/c/deps/db-4.8.30.NC/build_unix \
-L/c/deps/openssl-1.0.1l \
-L/c/deps/miniupnpc \
-L/c/deps/protobuf-2.6.1/src/.libs \
-L/c/deps/libpng-1.6.16/.libs \
-L/c/deps/qrencode-3.4.4/.libs" \
BOOST_ROOT=/c/deps/boost_1_57_0 \
./configure \
--disable-upnp-default \
--disable-tests \
--with-qt-incdir=/c/Qt/5.3.2/include \
--with-qt-libdir=/c/Qt/5.3.2/lib \
--with-qt-plugindir=/c/Qt/5.3.2/plugins \
--with-qt-bindir=/c/Qt/5.3.2/bin \
--with-protoc-bindir=/c/deps/protobuf-2.6.1/src

make

strip src/bitcoin-cli.exe
strip src/bitcoind.exe
strip src/qt/bitcoin-qt.exe

Additional notes:

64 bit binaries

64 bit binaries can be compiled by using the following toolchain:

All dependencies must be rebuilt with the above toolchain.

Openssl should be configured for:

mingw64

instead of:

mingw

Bitcoin v0.10rc4

Since v0.10 Bitcoin depends on gmp

Compile it in a msys shell

tar xvf gmp-6.0.0a.tar.xz
cd /c/deps/gmp-6.0.0
./configure --disable-shared
make

Then add relevant CPPFLAGS and LDFLAGS when configuring Bitcoin:

CPPFLAGS="-I/c/deps/db-4.8.30.NC/build_unix \
-I/c/deps/openssl-1.0.1l/include \
-I/c/deps \
-I/c/deps/protobuf-2.6.1/src \
-I/c/deps/libpng-1.6.16 \
-I/c/deps/qrencode-3.4.4 \
-I/c/deps/gmp-6.0.0" \
LDFLAGS="-L/c/deps/db-4.8.30.NC/build_unix \

-L/c/deps/libpng-1.6.16/.libs \
-L/c/deps/qrencode-3.4.4/.libs \
-L/c/deps/gmp-6.0.0/.libs" \
BOOST_ROOT=/c/deps/boost_1_57_0 \
./configure \
--disable-upnp-default \
--disable-tests \
--with-qt-incdir=/c/Qt/5.3.2/include \

--with-qt-bindir=/c/Qt/5.3.2/bin \
--with-protoc-bindir=/c/deps/protobuf-2.6.1/src

Compiling with unit tests

In order to build unit tests you will need the following: -boost

Boost must be configured with --with-test option also.

-hexdump

To generate test data an hexdump like program is needed. Download and unpack hexdump then compile hexdump.exe by running:

gcc -std=gnu99 -g -O2 -Wall -Wextra -Werror -Wno-unused-variable \
-Wno-unused-parameter hexdump.c -DHEXDUMP_MAIN -o hexdump.exe

Do not forget to add hexdump folder to your PATH environment variable.

-bitcoin

In order to work with the previously compiled hexdump version Makefile must be patched (src/Makefile.test.include if v0.10, src/Makefile.include if v0.9):

bitcoin must be configured without --disable-tests option.

Additional notes for older Bitcoin 0.8.6 (may be useful for Bitcoin based altcoins)

msys-autoconf, msys-automake and msys-libtool at step 1.1 are not needed. You can skip steps 2.5 and 2.7. Note that openssl v1.0.1k and later may lead to consensus forks

Compile bitcoind 0.8.6

With a texteditor edit BOOST_SUFFIX, INCLUDEPATHS and LIBPATHS in your C:\bitcoin-0.8.6\src\makefile.mingw according to your dependencies location:

Download and unpack Qt

Note that due to a bug in qt 4.8.6 you will need to explicitly enable windows styles.

Assuming Qt sources have been unpacked to C:\Qt\4.8.6, from a windows command prompt:

cd C:\Qt\4.8.6
configure -release -opensource -confirm-license -static -no-sql-sqlite -no-qt3support \
-no-opengl -qt-zlib -no-gif -qt-libpng -qt-libmng -no-libtiff -qt-libjpeg -no-dsp \
-no-vcproj -no-openssl -no-dbus -no-phonon -no-phonon-backend -no-multimedia \
-no-audio-backend -no-webkit -no-script -no-scripttools -no-declarative \
-no-declarative-debug -qt-style-windows -qt-style-windowsxp -qt-style-windowsvista \
-no-style-plastique -no-style-cleanlooks -no-style-motif -no-style-cde \
-nomake demos -nomake examples
mingw32-make

Note that if you skipped bitcoind compilation or if you have cleaned up your source folder you will need to compile libleveldb.a and libmemenv.a libraries before proceeding.

From msys shell:

cd /C/bitcoin-0.8.6/src/leveldb
TARGET_OS=NATIVE_WINDOWS make libleveldb.a libmemenv.a

Edit C:\bitcoin-0.8.6\bitcoin-qt.pro with your favourite text editor and add

dependency library locations:
