#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：
