Usage

To build dependencies for the current arch+OS:

make

To build for another arch/OS:

make HOST=host-platform-triplet

For example:

make HOST=x86_64-w64-mingw32 -j4

When configuring Bitcoin Core, CMake by default will ignore the depends output. In order for it to pick up libraries, tools, and settings from the depends build, you must specify the toolchain file. In the above example, a file named depends/x86_64-w64-mingw32/toolchain.cmake will be created. To use it during configuring Bitcoin Core:

cmake -B build --toolchain depends/x86_64-w64-mingw32/toolchain.cmake

Common host-platform-triplets for cross compilation are:

  • i686-pc-linux-gnu for Linux x86 32 bit
  • x86_64-pc-linux-gnu for Linux x86 64 bit
  • x86_64-w64-mingw32 for Win64
  • x86_64-apple-darwin for macOS
  • arm64-apple-darwin for ARM macOS
  • arm-linux-gnueabihf for Linux ARM 32 bit
  • aarch64-linux-gnu for Linux ARM 64 bit
  • powerpc64-linux-gnu for Linux POWER 64 bit (big endian)
  • powerpc64le-linux-gnu for Linux POWER 64 bit (little endian)
  • riscv32-linux-gnu for Linux RISC-V 32 bit
  • riscv64-linux-gnu for Linux RISC-V 64 bit
  • s390x-linux-gnu for Linux S390X

The paths are automatically configured and no other options are needed.

Install the required dependencies: Ubuntu & Debian

Common

apt install bison cmake curl make patch pkg-config python3 xz-utils

For macOS cross compilation

apt install clang lld llvm g++ zip

Clang 18 or later is required. You must also obtain the macOS SDK before proceeding with a cross-compile. Under the depends directory, create a subdirectory named SDKs. Then, place the extracted SDK under this new directory. For more information, see SDK Extraction.

For Win64 cross compilation

apt install g++-mingw-w64-x86-64-posix

For linux (including i386, ARM) cross compilation

Common linux dependencies:

sudo apt-get install g++-multilib binutils

For linux ARM cross compilation:

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

For linux AARCH64 cross compilation:

sudo apt-get install g++-aarch64-linux-gnu binutils-aarch64-linux-gnu

For linux POWER 64-bit cross compilation (there are no packages for 32-bit):

sudo apt-get install g++-powerpc64-linux-gnu binutils-powerpc64-linux-gnu g++-powerpc64le-linux-gnu binutils-powerpc64le-linux-gnu

For linux RISC-V 64-bit cross compilation (there are no packages for 32-bit):

sudo apt-get install g++-riscv64-linux-gnu binutils-riscv64-linux-gnu

For linux S390X cross compilation:

sudo apt-get install g++-s390x-linux-gnu binutils-s390x-linux-gnu

Install the required dependencies: FreeBSD

pkg install bash

Install the required dependencies: NetBSD

pkgin install bash gmake

Install the required dependencies: OpenBSD

pkg_add bash gmake gtar

Dependency Options

The following can be set when running make: make FOO=bar

  • SOURCES_PATH: Downloaded sources will be placed here
  • BASE_CACHE: Built packages will be placed here
  • SDK_PATH: Path where SDKs can be found (used by macOS)
  • FALLBACK_DOWNLOAD_PATH: If a source file can't be fetched, try here before giving up
  • C_STANDARD: Set the C standard version used. Defaults to c11.
  • CXX_STANDARD: Set the C++ standard version used. Defaults to c++20.
  • NO_BOOST: Don't download/build/cache Boost
  • NO_LIBEVENT: Don't download/build/cache Libevent
  • NO_QT: Don't download/build/cache Qt and its dependencies
  • NO_QR: Don't download/build/cache packages needed for enabling qrencode
  • NO_ZMQ: Don't download/build/cache packages needed for enabling ZeroMQ
  • NO_WALLET: Don't download/build/cache libs needed to enable the wallet
  • NO_BDB: Don't download/build/cache BerkeleyDB
  • NO_SQLITE: Don't download/build/cache SQLite
  • NO_USDT: Don't download/build/cache packages needed for enabling USDT tracepoints
  • MULTIPROCESS: Build libmultiprocess (experimental)
  • DEBUG: Disable some optimizations and enable more runtime checking
  • HOST_ID_SALT: Optional salt to use when generating host package ids
  • BUILD_ID_SALT: Optional salt to use when generating build package ids
  • LOG: Use file-based logging for individual packages. During a package build its log file resides in the depends directory, and the log file is printed out automatically in case of build error. After successful build log files are moved along with package archives
  • LTO: Enable options needed for LTO. Does not add -flto related options to *FLAGS.
  • NO_HARDEN=1: Don't use hardening options when building packages

If some packages are not built, for example make NO_WALLET=1, the appropriate CMake cache variables will be set when generating the Bitcoin Core buildsystem. In this case, -DENABLE_WALLET=OFF.

Additional targets

download: run 'make download' to fetch all sources without building them
download-osx: run 'make download-osx' to fetch all sources needed for macOS builds
download-win: run 'make download-win' to fetch all sources needed for win builds
download-linux: run 'make download-linux' to fetch all sources needed for linux builds
