Merge #18004: build: don't embed a build-id when building libdmg-hfsplus
cb9e88e73a build: don't embed a build-id when building libdmg-hfsplus (fanquake)

Pull request description:

  There was a [reproducibility issue (IRC logs)](http://www.erisian.com.au/bitcoin-core-dev/log-2020-01-25.html) with the osx `0.19.1rc1` gitian builds. The `build-id` embedded into the `dmg` tool was mismatching. It's possible that differing versions of binutils/ld were the cause.

  While it was resolved after rebuilding the base gitian image, whether an upstream package issue or fluke, we can remove the possibility of it happening in future by just not embedding a build-id into the `dmg` tool at all. Can close if it's not deemed worth it.

  You can test this change using the following:

  ```bash
  # build libdmg
  make native_libdmg-hfsplus_built -C depends/ HOST=x86_64-apple-darwin16 -j6 V=1

  # master
  readelf --string-dump .note.gnu.build-id /bitcoin/depends/work/build/x86_64-apple-darwin16/native_libdmg-hfsplus/7ac55ec64c96f7800d9818ce64c79670e7f02b67-3830944ef98/build/dmg/dmg

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 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 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-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.

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 Win64 cross compilation

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 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

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

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_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_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

Android

Before proceeding with an Android build one needs to get the Android SDK 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
