打算在Mac上编译TiKV，按照TiKV的文档，还缺cmake，但安装时得到：

1
Error: cmake: "cxx11" is not a recognized standard

查了下，也没有什么解决方案，最后找到这个答案，安装binary，在设置PATH

在Mac上跑了很久，也没见结束，先停了，打算换到服务器上跑

在GCP上新申请了一个账号，可以跑一个8核52G内存的VM，安装了CentOS 7.6

安装依赖

1
2
sudo yum install -y git cmake go clang # awk 和 make 已经有了
curl https://sh.rustup.rs -sSf | sh # 不能加sudo，加了之后装到/root用户目录下了（.cargo）

开始直接yum install了rust，之后有问题，只能删除

1
sudo yum -y remove rust

按照官网操作步骤

git clone https://github.com/tikv/tikv.git
cd tikv
# Future instructions assume you are in this repository

rustup component add rustfmt-preview
make build

make build 失败

CMake Error at CMakeLists.txt:1 (cmake_minimum_required):

切换到cmake3

sudo yum -y remove cmake 
sudo yum -y install cmake3 
mkdir ~/bin
ln -s /usr/bin/cmake3 ~/bin/cmake

--- stderr
CMake Error at CMakeLists.txt:31 (project):
  The CMAKE_CXX_COMPILER:

    c++

  is not a full path and was not found in the PATH.

  Tell CMake where to find the compiler by setting either the environment
  variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
  to the compiler, or to the compiler name if it is in the PATH.

没有c++，尝试

1
CXX=/usr/bin/clang++ make build

得到

CMake Error at /usr/share/cmake3/Modules/CMakeTestCXXCompiler.cmake:45 (message):
  The C++ compiler

    "/usr/bin/clang++"

最后不得不安装g++

yum install gcc-c++ libstdc++-devel
which c++
# /usr/bin/c++
make build

新错误

1
Could NOT find zlib (missing: ZLIB_LIBRARIES)

2
sudo yum -y install zlib-devel
make build

14:33 编译完成

1
2
cargo install cargo-watch
cargo watch -s "cargo check" # 这一句似乎并不会返回，似乎是一个监控的东西，只好另开窗口

新开窗口

1
make dev

结果得到raftstore::store::util::tests::test_lease测试失败，看到这个PR还在Open状态，说是时钟相关，在VMs中有问题

但执行单个test没事，全部通过

1
cargo test raftstore::store::util::tests::test_lease

继续

1
make release

得到

fix this by building tikv with ROCKSDB_SYS_SSE=1

看到TiKV的github也有类似Issue，但没有用，自己读了script，猜测是没有gdb，检查果然

1
2
gdb -batch -ex "disass/r _ZN7rocksdb6crc32c10ExtendImplIXadL_ZNS0_L10Fast_CRC32EPmPPKhEEEEjjPKcm" ./target/release/tikv-server
-bash: gdb: command not found

安装gdb

1
sudo yum -y install gdb

scripts/check-sse4_2.sh执行通过，着手创建PR，再次阅读相关Issue和PR，发现原来已经说了是gdb问题。花了点时间整理提交了PR，感觉精力耗尽。
