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 Limenka, 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 Limenka:

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 cmake curl make patch

GUI

Skip the following packages if you don't intend to use the GUI and will build with `NO_QT=1`:

apt install bison g++ pkgconf python3 xz-utils

For macOS cross compilation

apt install clang lld llvm 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 cmake curl gmake

Install the required dependencies: NetBSD

pkgin install bash cmake curl gmake perl

Install the required dependencies: OpenBSD

pkg_add bash cmake curl 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_UPNP: Don't download/build/cache packages needed for enabling UPnP
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 Limenka 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
