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

#编译grpc

cd $phx_dir/third_party/

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

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
