(For FreeBSD specific instructions, see `build-freebsd.md` in this directory.) Note --------------------- Always use absolute paths to configure and compile bitcoin and the dependencies, for example, when specifying the path of the dependency: ../dist/configure --enable-cxx --disable-shared --with-pic --prefix=$BDB_PREFIX Here BDB_PREFIX must be an absolute path - it is defined using $(pwd) which ensures the usage of the absolute path. To Build --------------------- Before you start building, please make sure that your compiler supports C++14. It is recommended to create a build directory to build out-of-tree. ```bash ./autogen.sh mkdir build cd build ../configure make make install # optional ``` This will build bitcoin-qt as well if the dependencies are met. Dependencies --------------------- These dependencies are required: Library | Purpose | Description ------------|------------------|---------------------- libssl | Crypto | Random Number Generation, Elliptic Curve Cryptography libboost | Utility | Library for threading, data structures, etc libevent | Networking | OS independent asynchronous networking Optional dependencies: Library | Purpose | Description ------------|------------------|---------------------- miniupnpc | UPnP Support | Firewall-jumping support libdb | Berkeley DB | Wallet storage (only needed when wallet enabled) qt | GUI | GUI toolkit (only needed when GUI enabled) protobuf | Payments in GUI | Data interchange format used for payment protocol (only needed when GUI enabled) libqrencode | QR codes in GUI | Optional for generating QR codes (only needed when GUI enabled) univalue | Utility | JSON parsing and encoding (bundled version will be used unless --with-system-univalue passed to configure) libzmq3 | ZMQ notification | Optional, allows generating ZMQ notifications (requires ZMQ version >= 4.x) For the versions used in the release, see [release-process.md](release-process.md) under *Fetch and build inputs*. Memory Requirements -------------------- C++ compilers are memory-hungry. It is recommended to have at least 1.5 GB of memory available when compiling Bitcoin ABC. On systems with less, gcc can be tuned to conserve memory with additional CXXFLAGS: ./configure CXXFLAGS="--param ggc-min-expand=1 --param ggc-min-heapsize=32768" Dependency Build Instructions: Ubuntu & Debian ---------------------------------------------- Build requirements: sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils Options when installing required Boost library files: 1. On at least Ubuntu 14.04+ and Debian 7+ there are generic names for the individual boost development packages, so the following can be used to only install necessary parts of boost: - sudo apt-get install libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev + sudo apt-get install libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-test-dev libboost-thread-dev 2. If that doesn't work, you can install all boost development packages with: sudo apt-get install libboost-all-dev BerkeleyDB 5.3 or later is required for the wallet. This can be installed with: sudo apt-get install libdb-dev libdb++-dev See the section "Disable-wallet mode" to build Bitcoin ABC without wallet. Optional (see --with-miniupnpc and --enable-upnp-default): sudo apt-get install libminiupnpc-dev ZMQ dependencies (provides ZMQ API 4.x): sudo apt-get install libzmq3-dev Dependencies for the GUI: Ubuntu & Debian ----------------------------------------- If you want to build Bitcoin-Qt, make sure that the required packages for Qt development are installed. Qt 5 is necessary to build the GUI. To build without GUI pass `--without-gui`. To build with Qt 5 you need the following: sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libqrencode (optional) can be installed with: sudo apt-get install libqrencode-dev Once these are installed, they will be found by configure and a bitcoin-qt executable will be built by default. Dependency Build Instructions: Fedora ------------------------------------- Build requirements: sudo dnf install gcc-c++ libtool make autoconf automake openssl-devel libevent-devel boost-devel libdb-devel libdb-cxx-devel Optional: sudo dnf install miniupnpc-devel To build with Qt 5 you need the following: sudo dnf install qt5-qttools-devel qt5-qtbase-devel protobuf-devel libqrencode (optional) can be installed with: sudo dnf install qrencode-devel Notes ----- The release is built with GCC and then "strip bitcoind" to strip the debug symbols, which reduces the executable size by about 90%. miniupnpc --------- [miniupnpc](http://miniupnp.free.fr/) may be used for UPnP port mapping. It can be downloaded from [here]( http://miniupnp.tuxfamily.org/files/). UPnP support is compiled in and turned off by default. See the configure options for upnp behavior desired: --without-miniupnpc No UPnP support miniupnp not required --disable-upnp-default (the default) UPnP support turned off by default at runtime --enable-upnp-default UPnP support turned on by default at runtime Boost ----- For documentation on building Boost look at their official documentation: http://www.boost.org/build/doc/html/bbv2/installation.html Security -------- To help make your bitcoin installation more secure by making certain attacks impossible to exploit even if a vulnerability is found, binaries are hardened by default. This can be disabled with: Hardening Flags: ./configure --enable-hardening ./configure --disable-hardening Hardening enables the following features: * Position Independent Executable Build position independent code to take advantage of Address Space Layout Randomization offered by some kernels. Attackers who can cause execution of code at an arbitrary memory location are thwarted if they don't know where anything useful is located. The stack and heap are randomly located by default but this allows the code section to be randomly located as well. On an AMD64 processor where a library was not compiled with -fPIC, this will cause an error such as: "relocation R_X86_64_32 against `......' can not be used when making a shared object;" To test that you have built PIE executable, install scanelf, part of paxutils, and use: scanelf -e ./bitcoin The output should contain: TYPE ET_DYN * Non-executable Stack If the stack is executable then trivial stack based buffer overflow exploits are possible if vulnerable buffers are found. By default, bitcoin should be built with a non-executable stack but if one of the libraries it uses asks for an executable stack or someone makes a mistake and uses a compiler extension which requires an executable stack, it will silently build an executable without the non-executable stack protection. To verify that the stack is non-executable after compiling use: `scanelf -e ./bitcoin` the output should contain: STK/REL/PTL RW- R-- RW- The STK RW- means that the stack is readable and writeable but not executable. Disable-wallet mode -------------------- When the intention is to run only a P2P node without a wallet, bitcoin may be compiled in disable-wallet mode with: ./configure --disable-wallet Mining is also possible in disable-wallet mode, but only using the `getblocktemplate` RPC call not `getwork`. Additional Configure Flags -------------------------- A list of additional configure flags can be displayed with: ./configure --help Setup and Build Example: Arch Linux ----------------------------------- This example lists the steps necessary to setup and build a command line only, non-wallet distribution of the latest changes on Arch Linux: pacman -S git base-devel boost libevent python git clone https://github.com/Bitcoin-ABC/bitcoin-abc.git cd bitcoin-abc/ ./autogen.sh ./configure --disable-wallet --without-gui --without-miniupnpc make check ARM Cross-compilation ------------------- These steps can be performed on, for example, an Ubuntu VM. The depends system will also work on other Linux distributions, however the commands for installing the toolchain will be different. Make sure you install the build requirements mentioned above. Then, install the toolchain and curl: sudo apt-get install g++-arm-linux-gnueabihf curl To build executables for ARM: cd depends make HOST=arm-linux-gnueabihf NO_QT=1 cd .. ./configure --prefix=$PWD/depends/arm-linux-gnueabihf --enable-glibc-back-compat --enable-reduce-exports LDFLAGS=-static-libstdc++ make For further documentation on the depends system see [README.md](../depends/README.md) in the depends directory. diff --git a/src/CMakeLists.txt b/src/CMakeLists.txt index cc56951f77..4ed789bc64 100644 --- a/src/CMakeLists.txt +++ b/src/CMakeLists.txt @@ -1,460 +1,460 @@ # Copyright (c) 2017 The Bitcoin developers cmake_minimum_required(VERSION 3.5) project(BitcoinABC) set(CMAKE_CXX_STANDARD 14) # Default visibility is hidden on all targets. set(CMAKE_C_VISIBILITY_PRESET hidden) set(CMAKE_CXX_VISIBILITY_PRESET hidden) option(BUILD_BITCOIN_WALLET "Activate the wallet functionality" ON) option(BUILD_BITCOIN_ZMQ "Activate the ZeroMQ functionalities" ON) option(BUILD_BITCOIN_SEEDER "Build bitcoin-seeder" ON) option(BUILD_BITCOIN_CLI "Build bitcoin-cli" ON) option(BUILD_BITCOIN_TX "Build bitcoin-tx" ON) option(BUILD_BITCOIN_QT "Build bitcoin-qt" ON) option(ENABLE_HARDENING "Harden the executables" ON) option(ENABLE_REDUCE_EXPORTS "Reduce the amount of exported symbols" OFF) option(ENABLE_STATIC_LIBSTDCXX "Statically link libstdc++" OFF) option(ENABLE_GLIBC_BACK_COMPAT "Enable Glibc compatibility features" OFF) option(ENABLE_QRCODE "Enable QR code display" ON) option(ENABLE_UPNP "Enable UPnP support" ON) option(START_WITH_UPNP "Make UPnP the default to map ports" OFF) # Allow usage of sanitizers by setting ECM_ENABLE_SANITIZERS if(ENABLE_SANITIZERS) set(ECM_ENABLE_SANITIZERS ${ENABLE_SANITIZERS}) find_package(ECM NO_MODULE) if(ECM_MODULE_PATH) list(APPEND CMAKE_MODULE_PATH ${ECM_MODULE_PATH}) include(ECMEnableSanitizers) else() message(FATAL_ERROR "ECM is required to enable the sanitizers (https://api.kde.org/ecm/index.html)" ) endif() endif() # Cmake uses the CMAKE_BUILD_TYPE variable to select the build configuration. # By default it supports more configurations that needed for Bitcoin ABC, and # all the releases types set NDEBUG which is unwanted as it disables the assert # completely. # Remove the -DNDEBUG flag from the CFLAGS/CXXFLAGS in all the configurations include(AddCompilerFlags) remove_compiler_flags(-DNDEBUG) # Overrides the flags for the Debug build type # This mimics the autotools behavior by setting the CFLAGS to '-g -O2`, which # are not well suited for debugging. # FIXME: update CFLAGS with better debug oriented optimization flags set(CMAKE_C_FLAGS_DEBUG "-g -O2") # Prefer -g3, defaults to -g if unavailable add_cxx_compiler_flag_with_fallback(CMAKE_CXX_FLAGS_DEBUG -g3 -g) # Prefer -Og, defaults to -O0 if unavailable add_cxx_compiler_flag_with_fallback(CMAKE_CXX_FLAGS_DEBUG -Og -O0) # Define the debugging symbols DEBUG and DEBUG_LOCKORDER when the Debug build # type is selected. string(APPEND CMAKE_CXX_FLAGS_DEBUG " -DDEBUG -DDEBUG_LOCKORDER") # Ensure that WINDRES_PREPROC is enabled when using windres. if(${CMAKE_SYSTEM_NAME} MATCHES "Windows") # Ensure that WINDRES_PREPROC is enabled when using windres. list(APPEND CMAKE_RC_FLAGS "-DWINDRES_PREPROC") # Build all static so there is no dll file to distribute. add_compiler_flag(-static) endif() if(ENABLE_REDUCE_EXPORTS) # Default visibility is set by CMAKE__VISIBILITY_PRESET, but this # doesn't tell if the visibility set is effective. # Check if the flag -fvisibility=hidden is supported, as using the hidden # visibility is a requirement to reduce exports. check_compiler_flag(HAS_CXX_FVISIBILITY CXX -fvisibility=hidden) if(NOT HAS_CXX_FVISIBILITY) message(FATAL_ERROR "Cannot set default symbol visibility.
