UNIX BUILD NOTES

Some notes on how to build Bitcoin Core in Unix.@H_403_1@

(for OpenBSD specific instructions,see build-openbsd.md)@H_403_1@

Note

Always use absolute paths to configure and compile bitcoin and the dependencies,for example,when specifying the path of the dependency:@H_403_1@

../dist/configure --enable-cxx --disable-shared --with-pic --prefix=$BDB_PREFIX

Here BDB_PREFIX must be an absolute path - it is defined using $(pwd) which ensuresthe usage of the absolute path.@H_403_1@

To Build

./autogen.sh
./configure
make
make install # optional

This will build bitcoin-qt as well if the dependencies are met.@H_403_1@

Dependencies

These dependencies are required:@H_403_1@

Library Purpose Description
libssl Crypto Random Number Generation,Elliptic Curve Cryptography
libboost Utility Library for threading,data structures,etc
libevent Networking OS independent asynchronous networking

Optional dependencies:@H_403_1@

Library Purpose Description
miniupnpc UPnP Support Firewall-jumping support
libdb4.8 Berkeley DB Wallet storage (only needed when wallet enabled)
qt GUI GUI toolkit (only needed when GUI enabled)
protobuf Payments in GUI Data interchange format used for payment protocol (only needed when GUI enabled)
libqrencode QR codes in GUI Optional for generating QR codes (only needed when GUI enabled)
univalue Utility JSON parsing and encoding (bundled version will be used unless --with-system-univalue passed to configure)
libzmq3 ZMQ notification Optional,allows generating ZMQ notifications (requires ZMQ version >= 4.x)

For the versions used,see dependencies.md@H_403_1@

Memory Requirements

C++ compilers are memory-hungry. It is recommended to have at least 1.5 GB ofmemory available when compiling Bitcoin Core. On systems with less,gcc can betuned to conserve memory with additional CXXFLAGS:@H_403_1@

./configure CXXFLAGS="--param ggc-min-expand=1 --param ggc-min-heapsize=32768"

Dependency Build Instructions: Ubuntu & Debian

Build requirements:@H_403_1@

sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils python3

Options when installing required Boost library files:@H_403_1@

  1. On at least Ubuntu 14.04+ and Debian 7+ there are generic names for theindividual boost development packages,so the following can be used to onlyinstall necessary parts of boost:@H_403_1@

    sudo apt-get install libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev
  2. If that doesn't work,you can install all boost development packages with:@H_403_1@

    sudo apt-get install libboost-all-dev

BerkeleyDB is required for the wallet.@H_403_1@

For Ubuntu only: db4.8 packages are available here.You can add the repository and install using the following commands:@H_403_1@

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt-get update
sudo apt-get install libdb4.8-dev libdb4.8++-dev

Ubuntu and Debian have their own libdb-dev and libdb++-dev packages,but these will installBerkeleyDB 5.1 or later,which break binary wallet compatibility with the distributed executables whichare based on BerkeleyDB 4.8. If you do not care about wallet compatibility,pass --with-incompatible-bdb to configure.@H_403_1@

See the section "Disable-wallet mode" to build Bitcoin Core without wallet.@H_403_1@

Optional (see --with-miniupnpc and --enable-upnp-default):@H_403_1@

sudo apt-get install libminiupnpc-dev

ZMQ dependencies (provides ZMQ API 4.x):@H_403_1@

sudo apt-get install libzmq3-dev

Dependencies for the GUI: Ubuntu & Debian

If you want to build Bitcoin-Qt,make sure that the required packages for Qt developmentare installed. Either Qt 5 or Qt 4 are necessary to build the GUI.If both Qt 4 and Qt 5 are installed,Qt 5 will be used. Pass --with-gui=qt4 to configure to choose Qt4.To build without GUI pass --without-gui.@H_403_1@

To build with Qt 5 (recommended) you need the following:@H_403_1@

sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler

Alternatively,to build with Qt 4 you need the following:@H_403_1@

sudo apt-get install libqt4-dev libprotobuf-dev protobuf-compiler

libqrencode (optional) can be installed with:@H_403_1@

sudo apt-get install libqrencode-dev

Once these are installed,they will be found by configure and a bitcoin-qt executable will bebuilt by default.@H_403_1@

Dependency Build Instructions: Fedora

Build requirements:@H_403_1@

sudo dnf install gcc-c++ libtool make autoconf automake openssl-devel libevent-devel boost-devel libdb4-devel libdb4-cxx-devel python3

Optional:@H_403_1@

sudo dnf install miniupnpc-devel

To build with Qt 5 (recommended) you need the following:@H_403_1@

sudo dnf install qt5-qttools-devel qt5-qtbase-devel protobuf-devel

libqrencode (optional) can be installed with:@H_403_1@

sudo dnf install qrencode-devel

Notes

The release is built with GCC and then "strip bitcoind" to strip the debugsymbols,which reduces the executable size by about 90%.@H_403_1@

miniupnpc

miniupnpc may be used for UPnP port mapping. It can be downloaded from here. UPnP support is compiled in andturned off by default. See the configure options for upnp behavior desired:@H_403_1@

--without-miniupnpc      No UPnP support miniupnp not required
--disable-upnp-default   (the default) UPnP support turned off by default at runtime
--enable-upnp-default    UPnP support turned on by default at runtime

Berkeley DB

It is recommended to use Berkeley DB 4.8. If you have to build it yourself:@H_403_1@

BITCOIN_ROOT=$(pwd)

# Pick some path to install BDB to,here we create a directory within the bitcoin directory
BDB_PREFIX="${BITCOIN_ROOT}/db4"
mkdir -p $BDB_PREFIX

# Fetch the source and verify that it is not tampered with
wget 'http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz'
echo '12edc0df75bf9abd7f82f821795bcee50f42cb2e5f76a6a281b85732798364ef  db-4.8.30.NC.tar.gz' | sha256sum -c
# -> db-4.8.30.NC.tar.gz: OK
tar -xzvf db-4.8.30.NC.tar.gz

# Build the library and install to our prefix
cd db-4.8.30.NC/build_unix/
#  Note: Do a static build so that it can be embedded into the executable,instead of having to find a .so at runtime
../dist/configure --enable-cxx --disable-shared --with-pic --prefix=$BDB_PREFIX
make install

# Configure Bitcoin Core to use our own-built instance of BDB
cd $BITCOIN_ROOT
./autogen.sh
./configure LDFLAGS="-L${BDB_PREFIX}/lib/" CPPFLAGS="-I${BDB_PREFIX}/include/" # (other args...)

Note: You only need Berkeley DB if the wallet is enabled (see the section Disable-Wallet mode below).@H_403_1@

Boost

If you need to build Boost yourself:@H_403_1@

sudo su
./bootstrap.sh
./bjam install

Security

To help make your bitcoin installation more secure by making certain attacks impossible toexploit even if a vulnerability is found,binaries are hardened by default.This can be disabled with:@H_403_1@

Hardening Flags:@H_403_1@

./configure --enable-hardening
./configure --disable-hardening

Hardening enables the following features:@H_403_1@

  • Position Independent ExecutableBuild position independent code to take advantage of Address Space Layout Randomizationoffered by some kernels. Attackers who can cause execution of code at an arbitrary memorylocation are thwarted if they don't know where anything useful is located.The stack and heap are randomly located by default but this allows the code section to berandomly located as well.@H_403_1@

    On an AMD64 processor where a library was not compiled with -fPIC,this will cause an errorsuch as: "relocation R_X86_64_32 against `......' can not be used when making a shared object;"@H_403_1@

    To test that you have built PIE executable,install scanelf,part of paxutils,and use:@H_403_1@

    scanelf -e ./bitcoin

    The output should contain:@H_403_1@

    TYPEET_DYN@H_403_1@

  • Non-executable StackIf the stack is executable then trivial stack based buffer overflow exploits are possible ifvulnerable buffers are found. By default,bitcoin should be built with a non-executable stackbut if one of the libraries it uses asks for an executable stack or someone makes a mistakeand uses a compiler extension which requires an executable stack,it will silently build anexecutable without the non-executable stack protection.@H_403_1@

    To verify that the stack is non-executable after compiling use:scanelf -e ./bitcoin@H_403_1@

    the output should contain:STK/REL/PTLRW- R-- RW-@H_403_1@

    The STK RW- means that the stack is readable and writeable but not executable.@H_403_1@

Disable-wallet mode

When the intention is to run only a P2P node without a wallet,bitcoin may be compiled indisable-wallet mode with:@H_403_1@

./configure --disable-wallet

In this case there is no dependency on Berkeley DB 4.8.@H_403_1@

Mining is also possible in disable-wallet mode,but only using the getblocktemplate RPCcall not getwork.@H_403_1@

Additional Configure Flags

A list of additional configure flags can be displayed with:@H_403_1@

./configure --help

Setup and Build Example: Arch Linux

This example lists the steps necessary to setup and build a command line only,non-wallet distribution of the latest changes on Arch Linux:@H_403_1@

pacman -S git base-devel boost libevent python
git clone https://github.com/bitcoin/bitcoin.git
cd bitcoin/
./autogen.sh
./configure --disable-wallet --without-gui --without-miniupnpc
make check

Note:Enabling wallet support requires either compiling against a Berkeley DB newer than 4.8 (package db) using --with-incompatible-bdb,or building and depending on a local version of Berkeley DB 4.8. The readily available Arch Linux packages are currently built using--with-incompatible-bdb according to the PKGBUILD.As mentioned above,when maintaining portability of the wallet between the standard Bitcoin Core distributions and independently builtnode software is desired,Berkeley DB 4.8 must be used.@H_403_1@

ARM Cross-compilation

These steps can be performed on,an Ubuntu VM. The depends systemwill also work on other Linux distributions,however the commands forinstalling the toolchain will be different.@H_403_1@

Make sure you install the build requirements mentioned above.Then,install the toolchain and curl:@H_403_1@

sudo apt-get install g++-arm-linux-gnueabihf curl

To build executables for ARM:@H_403_1@

cd depends
make HOST=arm-linux-gnueabihf NO_QT=1
cd ..
./configure --prefix=$PWD/depends/arm-linux-gnueabihf --enable-glibc-back-compat --enable-reduce-exports LDFLAGS=-static-libstdc++
make

For further documentation on the depends system see README.md in the depends directory.@H_403_1@

Building on FreeBSD

(Updated as of FreeBSD 11.0)@H_403_1@

Clang is installed by default as cc compiler,this makes it easier to getstarted than on OpenBSD. Installing dependencies:@H_403_1@

pkg install autoconf automake libtool pkgconf
pkg install boost-libs openssl libevent
pkg install gmake

You need to use GNU make (gmake) instead of make.(libressl instead of openssl will also work)@H_403_1@

For the wallet (optional):@H_403_1@

pkg install db5

This will give a warning "configure: WARNING: Found Berkeley DB otherthan 4.8; wallets opened by this build will not be portable!",but as FreeBSD neverhad a binary release,this may not matter. If backwards compatibilitywith 4.8-built Bitcoin Core is needed follow the steps under "Berkeley DB" above.@H_403_1@

Then build using:@H_403_1@

./autogen.sh
./configure --with-incompatible-bdb BDB_CFLAGS="-I/usr/local/include/db5" BDB_LIBS="-L/usr/local/lib -ldb_cxx-5"
gmake

Note on debugging: The version of gdb installed by default is ancient and considered harmful.It is not suitable for debugging a multi-threaded C++ program,not even for getting backtraces. Please install the package gdb anduse the versioned gdb command e.g. gdb7111.@H_403_1@
