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

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
