dash/depends

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

A prefix will be generated that's suitable for plugging into Dash's configure. In the above example, a dir named x86_64-w64-mingw32 will be created. To use it for Dash:

./configure --prefix=`pwd`/depends/x86_64-w64-mingw32

Common host-platform-triplets for cross compilation are:

• x86_64-w64-mingw32 for Win64
• x86_64-apple-darwin18 for macOS
• arm-linux-gnueabihf for Linux ARM 32 bit
• aarch64-linux-gnu for Linux ARM 64 bit
• riscv32-linux-gnu for Linux RISC-V 32 bit
• riscv64-linux-gnu for Linux RISC-V 64 bit

No other options are needed, the paths are automatically configured.

Install the required dependencies: Ubuntu & Debian

For macOS cross compilation:

sudo apt-get install curl librsvg2-bin libtiff-tools bsdmainutils imagemagick libcap-dev libz-dev libbz2-dev python3-setuptools

For Win64 cross compilation:

• see build-windows.md

For linux (including i386, ARM) cross compilation:

sudo apt-get install curl g++-aarch64-linux-gnu g++-4.8-aarch64-linux-gnu gcc-4.8-aarch64-linux-gnu binutils-aarch64-linux-gnu g++-arm-linux-gnueabihf g++-4.8-arm-linux-gnueabihf gcc-4.8-arm-linux-gnueabihf binutils-arm-linux-gnueabihf g++-4.8-multilib gcc-4.8-multilib binutils-gold bsdmainutils

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

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

RISC-V known issue: gcc-7.3.0 and gcc-7.3.1 result in a broken test_dash executable (see https://github.com/bitcoin/bitcoin/pull/13543), this is apparently fixed in gcc-8.1.0.

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 sdk's can be found (used by macOS)

FALLBACK_DOWNLOAD_PATH

If a source file can't be fetched, try here before giving up

NO_QT

Don't download/build/cache qt and its dependencies

NO_WALLET

Don't download/build/cache libs needed to enable the wallet

NO_UPNP

Don't download/build/cache packages needed for enabling upnp

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

FORCE_USE_SYSTEM_CLANG

(EXPERTS ONLY) When cross-compiling for macOS, use clang found in the system's $PATH rather than the default prebuilt release of clang from llvm.org

If some packages are not built, for example `make NO_WALLET=1`, the appropriate options will be passed to Dash Core's configure. In this case, `--disable-wallet`.

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
