超级账本子项目 iroha 私链部署

安装

  ==尽量采用高版本的Ubuntu内核版本或GCC版本==

依赖包

• 下载 iroha
  
git clone -b https://github.com/hyperledger/iroha


• 环境配置

  sudo apt-get install build-essential python-software-properties automake libtool \
  libssl-dev zlib1g-dev  libc6-dbg golang \
  ca-certificates lcov  cmake iputils-ping ccache gcovr vera++\
  cppcheck doxygen graphviz graphviz-dev libgtest-dev libgflags-dev
  

  • cmake

    
    # 下载 cmake 安装脚本
    
    wget https://cmake.org/files/v3.10/cmake-3.10.3-Linux-x86_64.sh
    
    
    # 安装
    
    sudo sh cmake-3.10.3-Linux-x86_64.sh
    
    
    # 根据提示选择安装路径
    
    
    # 配置环境变量 修改 .bashrc
    
    vim ~/.bashrc
    export PATH="/cmake/install/path/bin:$PATH"
    
    # 加载环境变量
    
    source ~/.bashrc

  • boost
    
    ==注： Boost v1.65运行正常, v1.66运行 coredump==

    
    # download boost
    
    wget https://dl.bintray.com/boostorg/release/1.65.0/source/boost_1_65_0.tar.gz
    
    # 编译
    
    ./bootstrap.sh --with-libraries=system,filesystem 
    ./b2

  • libcares

    
    # 编译安装
    
    wget https://c-ares.haxx.se/download/c-ares-1.14.0.tar.gz
    ./configure
    make && sudo make install

  • protobuf

    
    # 编译添加fPIC 解决静态库依赖错误
    
    ./configure CXXFLAGS=-fPIC
    make && sudo make install

  ==注： 编译Google全家桶时，修改gcc 版本对应的cplusplus c++config.h 文件中的宏 _GLIBCXX_USE_CXX11_ABI 为0 ; 例如： /usr/include/x86_64-linux-gnu/c++/6/bits/c++config.h
  ; 否则后续编译可能会出现 动态库引用 undefined==

  • grpc
    

    
    # 安装依赖包
    
    sudo apt-get install libgoogle-perftools-dev build-essential\
    autoconf libtool pkg-config
    
    
    # 下载最新代码包
    
    git clone https://github.com/grpc/grpc.git
    git submodule update --init
    
    make && sudo make instal

  若GCC版本过低可能会遇见如下问题：

  
  # grpc_cpp_plugin 运行 coredump
  
  terminate called after throwing an instance of 'std::system_error

  解决方案， 修改Makefile, 添加 -Wl,--no-as-needed 编译参数， 具体参考Stackoverflow: terminate called after throwing an instance of ‘std::system_error’

  379 ifeq ($(SYSTEM),Linux)
  380 LIBS = dl rt m pthread
  381 LDFLAGS += -pthread -Wl,--no-as-needed
  382 endif
  383 
  384 ifeq ($(SYSTEM),MINGW32)
  385 LIBS = m pthread ws2_32
  386 LDFLAGS += -pthread
  387 endif

常见问题

GCC 升级

• 手动升级
  

  1. gcc6.3.0的源代码压缩包，下载地址：

  镜像站点：

  https://gcc.gnu.org/mirrors.htm
  
  ftp://ftp.mirrorservice.org/sites/sourceware.org/pub/gcc/releases/

  1. 四个压缩包：

  m4：http://www.gnu.org/software/m4/m4.html

  gmp：https://gmplib.org/

  mpfr：http://www.mpfr.org/

  mpc：http://www.multiprecision.org/

  依次安装编译上述依赖包

  1. 编译

     
     # gcc 配置
     
     ./configure --prefix=/usr/local/gcc-6.3 --enable-threads=posix --disable-checking --disable-multilib --enable-languages=c,c++ --program-suffix=6.3.0
     
     
     # 在编译GCC的过程中可能出现“configure: error: cannot compute suffix of object files: cannot compile”的错误，解决方法是：
     
     
     export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/
     
     make -j4 && sudo make install

  2. 指定GCC版本

     export CC=/usr/local/gcc-6.3/bin/gcc
     export CXX=/usr/local/gcc-6.3/bin/g++
     export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/:/usr/local/gcc-6.3/lib/:/usr/local/gcc-6.3/lib64/

gtest undefined reference 错误

  ed25519_test.cpp:(.text+0x4ab): undefined reference to `testing::internal::GetBoolAssertionFailureMessage[abi:cxx11](testing::AssertionResult const&, char const*, char const*, char const*)’

  修改文件
vim /usr/local/gcc-5.5/include/c++/5.5.0/x86_64-unknown-linux-gnu/bits/c++config.h
  #define _GLIBCXX_USE_CXX11_ABI 0

  If you get linker errors about undefined references to symbols that involve types in the std::__cxx11 namespace or the tag [abi:cxx11] then it probably indicates that you are trying to link together object files that were compiled with different values for the _GLIBCXX_USE_CXX11_ABI macro. This commonly happens when linking to a third-party library that was compiled with an older version of GCC. If the third-party library cannot be rebuilt with the new ABI then you will need to recompile your code with the old ABI.

cmake cannot find lpthreads

ERROR: cmake cannot find lpthreads

解决方案：
修改 cmake/dependencies.cmake 文件注释掉 #find_package(Threads REQUIRED)

irohad coredump

1、修改CMakeList.txt 中 DEBUG 编译参数选项 SET(CMAKE_CXX_FLAGS_DEBUG "-g -ggdb -Wextra -Wno-unused-parameter -Wno-deprecated-declarations -O0")

2、重新编译

# 默认 -DCMAKE_BUILD_TYPE=Debug
cmake -H. -Bbuild
cd build && make -j4

3、修改 ulimit -c 的值

prod@ubuntu:~/blockchain/iroha$ ulimit -c unlimited
prod@ubuntu:~/blockchain/iroha$ ulimit -c
unlimited

4、运行irohad 生成 coredump 文件

gdb irohad --config conf/config.json --genesis_block init/genesis.block --keypair_name init/node0 [corefile]
