编译ClickHouse源码 导入CLion

基础信息

• OS：MacOS Mojave 10.14.6
• ClickHouse: master branch
• 在Mac上编译ClickHouse只支持Clang编译器
• 使用Mac的本地编译器和gcc都会报错

编译过程

安装Homebrew，已安装可跳过

brew -v
Homebrew 2.5.9
Homebrew/homebrew-core (git revision 58b4b; last commit 2020-11-11)

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

安装需要的基础组件

brew install cmake ninja libtool gettext

安装CLang

检查

brew info llvm

安装

brew install llvm

获取llvm的安装信息，用于设置编译

To use the bundled libc++ please add the following LDFLAGS:
  LDFLAGS="-L/usr/local/opt/llvm/lib -Wl,-rpath,/usr/local/opt/llvm/lib"

llvm is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have llvm first in your PATH run:
  echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> /Users/${user}/.bash_profile

For compilers to find llvm you may need to set:
  export LDFLAGS="-L/usr/local/opt/llvm/lib"
  export CPPFLAGS="-I/usr/local/opt/llvm/include"

编译

cd ClickHouse
mkdir build
cd build
cmake .. -DCMAKE_C_COMPILER=/usr/local/opt/llvm/bin/clang -DCMAKE_CXX_COMPILER=/usr/local/opt/llvm/bin/clang++ -DCMAKE_BUILD_TYPE=Debug
ninja
cd ..

报错

objcopy

Cannot find objcopy.

解决办法参考参考目录

注意

• 每次编译没成功之前，删除编译失败产生的文件

运行

运行方法

cd /programs
./clickhouse-server server --config-file=../../programs/server/config.xml 

注意编译产生的目录结构可能不同，需要查看寻找执行文件
使用的配置文件位置也可能不同
可以在ClickHouse源码根目录使用下面的命令查找

find ./ -name config.xml

报错

Code: 102. DB::NetException: Unexpected packet from server localhost:9000 (expected Hello or Exception, got Unknown packet)

lsof -i:9000

kill 掉

 kill 2989

再次连接成功

./clickhouse-client -m

导入到Clion

导入ClickHouse源码

将CMakeLists.txt所在根目录导入到Clion中

配置正确的clang路径

默认情况下，clion可以探测出正确的编译器，但是在mac上，至少我的环境中探测出的编译器是App，并不work

默认探测的编译器

需要配置一个正取的编译器

配置系统中正取的编译器

报错

WARNING "CCache is not found. We recommend setting it up if you build ClickHouse from source often. "

添加环境变量
