一次失败的尝试：paxosstore示例编译

本来想编译paxosstore的example，没想到最终还是失败了。

git clone https://github.com/Tencent/paxosstore.git
cd paxosstore
git submodule update --init --recursive

然后安装有用的库：

apt install zlib1g-dev libssl-dev  libpcap-dev libelf-dev libicu-dev libreadline-dev libtool  libsysfs-dev \
libsqlite3-dev libbz2-dev libreadline-dev zlib1g-dev liblzma-dev liblzo2-dev   \
libsnappy-dev  liblz4-dev libzstd-dev libgflags-dev  libprotoc-dev

编译：

cd certain
./build.sh example

会报错：network/IOChannel.cpp:127:16: error: ‘writev’ was not declared in this scope

然后在network/IOChannel.cpp添加头文件：

#include<sys/uio.h>

接着报错：error: this statement may fall through [-Werror=implicit-fallthrough=]
解决方法：

export CFLAGS='-Wno-implicit-fallthrough'

然后报错：

./third/protobuf/src/protoc --grpc_out=./ --plugin=protoc-gen-grpc=./third/grpc/bins/opt/grpc_cpp_plugin example/example.proto
./third/grpc/bins/opt/grpc_cpp_plugin: program not found or is not executable
--grpc_out: protoc-gen-grpc: Plugin failed with status code 1.
Makefile:95: recipe for target 'example/example.grpc.pb.cc' failed
make: *** [example/example.grpc.pb.cc] Error 1
make: *** Waiting for unfinished jobs....
rm src/Certain.pb.cc

参考：grpc/run_distrib_test_cmake.sh at master · grpc/grpc

这是因为grpc编译没完成，有错误，解决方法：

mv grpc grpc2
git clone https://github.com/grpc/grpc.git
cd grpc
git submodule update --init
make REQUIRE_CUSTOM_LIBRARIES_opt=1 static
cmake . -DgRPC_PROTOBUF_PROVIDER=package -DgRPC_ZLIB_PROVIDER=package -DgRPC_CARES_PROVIDER=package -DgRPC_SSL_PROVIDER=package
make
cp *.a libs/opt/

可能会报错：

g++: error: ./third/grpc/libs/opt/libz.a: No such file or directory
g++: error: ./third/grpc/libs/opt/libgrpc++_reflection.a: No such file or directory

解决方法：

cd third_party/cares/cares
mkdir -p cmake/build
cd cmake/build
cmake -DCMAKE_BUILD_TYPE=Release ../..
make -j4 install
cd ../../../../..


# Install zlib
cd third_party/zlib
mkdir -p cmake/build
cd cmake/build
cmake -DCMAKE_BUILD_TYPE=Release ../..
make -j4 install
cd ../../../..


# Install protobuf
cd third_party/protobuf
mkdir -p cmake/build
cd cmake/build
cmake -Dprotobuf_BUILD_TESTS=OFF -DCMAKE_BUILD_TYPE=Release ..
make -j4 install
cd ../../../..

# Install gRPC
mkdir -p cmake/build
cd cmake/build
cmake -DgRPC_INSTALL=ON -DgRPC_BUILD_TESTS=OFF -DgRPC_PROTOBUF_PROVIDER=package -DgRPC_ZLIB_PROVIDER=package -DgRPC_CARES_PROVIDER=package -DgRPC_SSL_PROVIDER=package -DCMAKE_BUILD_TYPE=Release ../..
make -j4 install
cd ../..

只能说我找了很多解决方案，最终还是没找到解决方法，这次尝试算是比较失败的一次了。

毕竟花费了挺多的时间，最终解决不了还是挺不爽的。
