Making a copy if the world stops bitcointalk

Building headless Bitcoin and Bitcoin-qt on Windows March 05, 2013, 10:26:41 PM Merited by neiros (1), cinnamon_carter (1), fisheater (1), ItaCraft (1) #1 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. Wink

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: Code: 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: Code: $ 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 Target: i686-w64-mingw32 Configured with: ../../../src/gcc-4.9.2/configure --host=i686-w64-mingw32 --build=i686-w64-mingw32 --target=i686-w64-mingw32 --prefix=/mingw32 --with-sysroot=/c/mingw492/i686-492-posix-dwarf-rt_v3-rev1/mingw32 --with-gxx-include-dir=/mingw32/i686-w64-mingw32/include/c++ --enable-shared --enable-static --disable-multilib --enable-languages=ada,c,c++,fortran,objc,obj-c++,lto --enable-libstdcxx-time=yes --enable-threads=posix --enable-libgomp --enable-libatomic --enable-lto --enable-graphite --enable-checking=release --enable-fully-dynamic-string --enable-version-specific-runtime-libs --disable-sjlj-exceptions --with-dwarf2 --disable-isl-version-check --disable-cloog-version-check --disable-libstdcxx-pch --disable-libstdcxx-debug --enable-bootstrap --disable-rpath --disable-win32-registry --disable-nls --disable-werror --disable-symvers --with-gnu-as --with-gnu-ld --with-arch=i686 --with-tune=generic --with-libiconv --with-system-zlib --with-gmp=/c/mingw492/prerequisites/i686-w64-mingw32-static --with-mpfr=/c/mingw492/prerequisites/i686-w64-mingw32-static --with-mpc=/c/mingw492/prerequisites/i686-w64-mingw32-static --with-isl=/c/mingw492/prerequisites/i686-w64-mingw32-static --with-cloog=/c/mingw492/prerequisites/i686-w64-mingw32-static --enable-cloog-backend=isl --with-pkgversion='i686-posix-dwarf-rev1, Built by MinGW-W64 project' --with-bugurl=http://sourceforge.net/projects/mingw-w64 CFLAGS='-O2 -pipe -I/c/mingw492/i686-492-posix-dwarf-rt_v3-rev1/mingw32/opt/include -I/c/mingw492/prerequisites/i686-zlib-static/include -I/c/mingw492/prerequisites/i686-w64-mingw32-static/include' CXXFLAGS='-O2 -pipe -I/c/mingw492/i686-492-posix-dwarf-rt_v3-rev1/mingw32/opt/include -I/c/mingw492/prerequisites/i686-zlib-static/include -I/c/mingw492/prerequisites/i686-w64-mingw32-static/include' CPPFLAGS= LDFLAGS='-pipe -L/c/mingw492/i686-492-posix-dwarf-rt_v3-rev1/mingw32/opt/lib -L/c/mingw492/prerequisites/i686-zlib-static/lib -L/c/mingw492/prerequisites/i686-w64-mingw32-static/lib -Wl,--large-address-aware' Thread model: posix gcc version 4.9.2 (i686-posix-dwarf-rev1, Built by MinGW-W64 project)

2. Download, unpack and build required dependencies. I'll save them in c:\deps folder.

2.1 OpenSSL: http://www.openssl.org/source/openssl-1.0.1l.tar.gz 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: Code: 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: http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz We'll use version 4.8 to preserve binary wallet compatibility. From a MinGW shell unpack the source archive, configure and make: Code: 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: http://sourceforge.net/projects/boost/files/boost/1.57.0/ Download either the zip or the 7z archive, unpack boost inside your C:\deps folder, then bootstrap and compile from a Windows command prompt: Code: 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: http://miniupnp.free.fr/files/download.php?file=miniupnpc-1.9.20150206.tar.gz Unpack Miniupnpc to C:\deps, rename containing folder from "miniupnpc-1.9.20150206" to "miniupnpc" then from a Windows command prompt: Code: cd C:\deps\miniupnpc mingw32-make -f Makefile.mingw init upnpc-static

2.5 protoc and libprotobuf: Download https://github.com/google/protobuf/releases/download/v2.6.1/protobuf-2.6.1.tar.gz Then from msys shell Code: 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 http://download.sourceforge.net/libpng/libpng-1.6.16.tar.gz inside your deps folder then configure and make: Code: cd /c/deps/libpng-1.6.16 configure --disable-shared make cp .libs/libpng16.a .libs/libpng.a

Download and unpack http://fukuchi.org/works/qrencode/qrencode-3.4.4.tar.gz inside your deps folder then configure and make: Code: 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 tools sources: http://download.qt-project.org/official_releases/qt/5.3/5.3.2/submodules/qtbase-opensource-src-5.3.2.7z http://download.qt-project.org/official_releases/qt/5.3/5.3.2/submodules/qttools-opensource-src-5.3.2.7z 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): Code: 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. Download and unpack Bitcoin 0.9.4 from git https://github.com/bitcoin/bitcoin/archive/v0.9.4.zip

From msys shell configure and make bitcoin: Code: 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

BOOST_ROOT=/c/deps/boost_1_57_0
./configure

--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: http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/4.9.2/threads-posix/seh/x86_64-4.9.2-release-posix-seh-rt_v3-rev1.7z/download

All dependencies must be rebuilt with the above toolchain. Openssl should be configured for: Code: mingw64 instead of: Code: mingw

Bitcoin v0.10rc4 Since v0.10 Bitcoin depends on gmp: https://gmplib.org/download/gmp/gmp-6.0.0a.tar.xz Compile it in a msys shell Code: 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: Code: 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

-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
-L/c/deps/gmp-6.0.0/.libs"
BOOST_ROOT=/c/deps/boost_1_57_0
./configure

--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

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 https://github.com/wahern/hexdump then compile hexdump.exe by running: Code: 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): Code: --- src/Makefile.test.include Tue Dec 23 20:14:37 2014 +++ src/Makefile.test.include Sat Jan 10 16:53:56 2015 @@ -111,7 +111,7 @@ @$(MKDIR_P) $(@D) @echo "namespace json_tests{" > $@ @echo "static unsigned const char $(*F)[] = {" >> $@

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 consesus forks: http://sourceforge.net/p/bitcoin/mailman/message/33221963/
