### 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
|
|
|
|
**Litecoin Core'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 Litecoin:
|
|
|
|
./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-darwin16` for 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
|
|
- `armv7a-linux-android` for Android ARM 32 bit
|
|
- `aarch64-linux-android` for Android ARM 64 bit
|
|
- `i686-linux-android` for Android x86 32 bit
|
|
- `x86_64-linux-android` for Android x86 64 bit
|
|
|
|
The paths are automatically configured and no other options are needed unless targeting [Android](#Android).

### Install the required dependencies: Ubuntu & Debian
|
|
|
|

|
|
|

|
|
|
|

|
|
|

|
|
|

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.
|
|
|
|
For linux S390X cross compilation:
|
|
|
|
sudo apt-get install g++-s390x-linux-gnu binutils-s390x-linux-gnu
|
|
|
|
### Dependency Options
|
|
The following can be set when running make: `make FOO=bar`
|
|
|
|
<dl>
|
|
<dt>SOURCES_PATH</dt>

|
|
<dt>ALLOW_HOST_PACKAGES</dt>
|
|
<dd>Packages that are missed in dependencies (due to `NO_*` option or
|
|
build script logic) are searched for among the host system packages using
|
|
`pkg-config`. It allows building with packages of other (newer) versions</dd>
|
|
<dt>MULTIPROCESS</dt>
|
|
<dd>build libmultiprocess (experimental, requires cmake)</dd>
|
|
<dt>DEBUG</dt>
|
|
<dd>disable some optimizations and enable more runtime checking</dd>
|
|
<dt>HOST_ID_SALT</dt>
|
|
<dd>Optional salt to use when generating host package ids</dd>
|
|
<dt>BUILD_ID_SALT</dt>
|
|
<dd>Optional salt to use when generating build package ids</dd>
|
|
<dt>FORCE_USE_SYSTEM_CLANG</dt>
|
|
<dd>(EXPERTS ONLY) When cross-compiling for macOS, use Clang found in the
|
|
system's <code>$PATH</code> rather than the default prebuilt release of Clang
|
|
from llvm.org. Clang 8 or later is required.</dd>
|
|
</dl>
|
|
|
|
If some packages are not built, for example `make NO_WALLET=1`, the appropriate
|
|
options will be passed to litecoin'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
|
|
|
|
|
|
### Android
|
|
|
|
Before proceeding with an Android build one needs to get the [Android SDK](https://developer.android.com/studio) and use the "SDK Manager" tool to download the NDK and one or more "Platform packages" (these are Android versions and have a corresponding API level).
|
|
In order to build `ANDROID_API_LEVEL` (API level corresponding to the Android version targeted, e.g. Android 9.0 Pie is 28 and its "Platform package" needs to be available) and `ANDROID_TOOLCHAIN_BIN` (path to toolchain binaries depending on the platform the build is being performed on) need to be set.
|
|
|
|
API levels from 24 to 29 have been tested to work.
|
|
|
|
If the build includes Qt, environment variables `ANDROID_SDK` and `ANDROID_NDK` need to be set as well but can otherwise be omitted.
|
|
This is an example command for a default build with no disabled dependencies:
|
|
|
|
ANDROID_SDK=/home/user/Android/Sdk ANDROID_NDK=/home/user/Android/Sdk/ndk-bundle make HOST=aarch64-linux-android ANDROID_API_LEVEL=28 ANDROID_TOOLCHAIN_BIN=/home/user/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin
