If not cross compiling, it might actually be nice for it to be picked up automatically. But for now clarify the readme to try to minimize confusion. https://github.com/chaincodelabs/libmultiprocess/issues/4#issuecomment-515619707 https://github.com/chaincodelabs/libmultiprocess/issues/5#issuecomment-518826298

### 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
|
|
|
|
**Bitcoin's configure script by default will ignore the depends output.** In
|
|
order for it to pick up libraries, tools, and settings from the depends build,
|
|
you must point it at the appropriate `--prefix` directory generated by the
|
|
build. In the above example, a prefix dir named x86_64-w64-mingw32 will be
|
|
created. To use it for Bitcoin:
|
|
|
|
./configure --prefix=`pwd`/depends/x86_64-w64-mingw32
|
|
|
|
Common `host-platform-triplets` for cross compilation are:
|
|
|
|
- `i686-pc-linux-gnu` for Linux 32 bit
|
|
- `x86_64-pc-linux-gnu` for x86 Linux
|
|
- `x86_64-w64-mingw32` for Win64
|
|
- `x86_64-apple-darwin14` 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 cmake imagemagick libcap-dev libz-dev libbz2-dev python3-setuptools
|
|
|
|
#### For Win32/Win64 cross compilation
|
|
|
|
- see [build-windows.md](../doc/build-windows.md#cross-compilation-for-ubuntu-and-windows-subsystem-for-linux)
|
|
|
|
#### For linux (including i386, ARM) cross compilation
|
|
|
|
Common linux dependencies:
|
|
|
|
sudo apt-get install make automake cmake curl g++-multilib libtool binutils-gold bsdmainutils pkg-config python3 patch
|
|
|
|
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 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
|
|
|
|
RISC-V known issue: gcc-7.3.0 and gcc-7.3.1 result in a broken `test_bitcoin` 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_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_UPNP: Don't download/build/cache packages needed for enabling upnp
|
|
DEBUG: disable some optimizations and enable more runtime checking
|
|
RAPIDCHECK: build rapidcheck (experimental, requires cmake)
|
|
HOST_ID_SALT: Optional salt to use when generating host package ids
|
|
BUILD_ID_SALT: Optional salt to use when generating build package ids
|
|
|
|
If some packages are not built, for example `make NO_WALLET=1`, the appropriate
|
|
options will be passed to bitcoin'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
|
|
