腾讯开源项目phxpaxos的编译步骤

#paxos的一般编译流程在项目文档《中文详细编译手册》里面已经有介绍，这里重点介绍一下编译samples目录下的代码；

#我的环境是ubuntu;

#设置paxos根目录

    phx_dir=~/code/tencent/phxpaxos/

#编译leveldb

    cd $phx_dir/third_party/leveldb

    make

    mkdir lib

    cd lib

    ln -s ../libleveldb.a libleveldb.a

#编译protobuf

    cd $phx_dir/third_party/protobuf

    ./autogen.sh

    ./configure CXXFLAGS=-fPIC --prefix=`pwd`

    make && make install

#编译glog

    cd $phx_dir/third_party/glog

    ./configure CXXFLAGS=-fPIC -prefix=`pwd`

    make && make install

   

#有时候我们在phxpaxos代码里面改了东西，但是sample工程不能生效，

#所以我们在编译 libphxpaxos.a 和 libphxpaxos_plugin.a 的时候先删掉之前的静态库

#然后在编译 sample 代码的时候先执行一下 make clean

#编译phxpaxos静态库

    cd $phx_dir

    find ./ -name "libphxpaxos.a" | xargs rm

    find ./ -name "libphxpaxos_plugin.a" | xargs rm

    ./autoinstall.sh

    make debug=y && make install

    ll lib/

#编译PhxPaxos Plugin静态库

    cd $phx_dir/plugin

    make && make install

    ll ../lib

   

#编译gtest和gmock

    cd $phx_dir/third_party

    rm -rf googlemock

    git clone --recursive https://github.com/google/googletest.git

    cd googletest

    cmake -DCMAKE_INSTALL_PREFIX=`pwd` .

    make && make install

    cd $phx_dir/third_party/

    mkdir gmock

    mv googletest/{include,lib} ./gmock

    cd gmock

    mv lib64 lib

#grpc依赖于openssl，请下载最新的openssl并编译安装

    openssl编译步骤略

    grpc依赖于openssl，如果有 libssl.a 链接错误，请下载最新的openssl并编译安装

    附错误提示：

    [LD] Linking third_party/grpc/libs/opt/libgrpc.so.7.0.0-dev

    /usr/bin/ld: /usr/local/lib/libssl.a(t1_meth.o): relocation R_X86_64_32 against .rodata can not be used when making a shared object; recompile with -fPIC

    /usr/local/lib/libssl.a: error adding symbols: Bad value

   

#编译grpc

    cd $phx_dir/third_party/

    git clone --recursive https://github.com/grpc/grpc.git

    make

    mkdir bin

    cp -rf bins/* bin/

    mkdir lib

    cp -rf libs/* lib/

    cp -rf libs/opt/* lib/

   

#把grpc的路径加到环境变量

    export PATH=$phx_dir/third_party/grpc/bins/opt/:$phx_dir/third_party/grpc/bins/opt/protobuf:$PATH

    which grpc_cpp_plugin

    which protoc

#编译例子

    cd $phx_dir/sample

    make

#修改代码之后的快速重编
