How to Build ClickHouse on Mac OS X

:::info You don't have to build ClickHouse yourself! You can install pre-built ClickHouse as described in Quick Start. Follow macOS (Intel) or macOS (Apple silicon) installation instructions. :::

Build should work on x86_64 (Intel) and arm64 (Apple silicon) based macOS 10.15 (Catalina) and higher with Homebrew's vanilla Clang. It is always recommended to use vanilla clang compiler.

:::note It is possible to use XCode's apple-clang or gcc, but it's strongly discouraged. :::

Install Homebrew

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
# ...and follow the printed instructions on any additional steps required to complete the installation.

Install Xcode and Command Line Tools

Install the latest Xcode from App Store.

Open it at least once to accept the end-user license agreement and automatically install the required components.

Then, make sure that the latest Command Line Tools are installed and selected in the system:

sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install

Install Required Compilers, Tools, and Libraries

brew update
brew install cmake ninja libtool gettext llvm gcc binutils

Checkout ClickHouse Sources

git clone --recursive git@github.com:ClickHouse/ClickHouse.git
# ...alternatively, you can use https://github.com/ClickHouse/ClickHouse.git as the repo URL.

Build ClickHouse

To build using Homebrew's vanilla Clang compiler (the only recommended way):

cd ClickHouse
rm -rf build
mkdir build
cd build
cmake -DCMAKE_C_COMPILER=$(brew --prefix llvm)/bin/clang -DCMAKE_CXX_COMPILER=$(brew --prefix llvm)/bin/clang++ -DCMAKE_AR=$(brew --prefix llvm)/bin/llvm-ar -DCMAKE_RANLIB=$(brew --prefix llvm)/bin/llvm-ranlib -DOBJCOPY_PATH=$(brew --prefix llvm)/bin/llvm-objcopy -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
cmake --build . --config RelWithDebInfo
# The resulting binary will be created at: ./programs/clickhouse

To build using Xcode's native AppleClang compiler in Xcode IDE (this option is only for development builds and workflows, and is not recommended unless you know what you are doing):

cd ClickHouse
rm -rf build
mkdir build
cd build
XCODE_IDE=1 ALLOW_APPLECLANG=1 cmake -G Xcode -DCMAKE_BUILD_TYPE=Debug -DENABLE_JEMALLOC=OFF ..
cmake --open .
# ...then, in Xcode IDE select ALL_BUILD scheme and start the building process.
# The resulting binary will be created at: ./programs/Debug/clickhouse

To build using Homebrew's vanilla GCC compiler (this option is only for development experiments, and is absolutely not recommended unless you really know what you are doing):

cd ClickHouse
rm -rf build
mkdir build
cd build
cmake -DCMAKE_C_COMPILER=$(brew --prefix gcc)/bin/gcc-11 -DCMAKE_CXX_COMPILER=$(brew --prefix gcc)/bin/g++-11 -DCMAKE_AR=$(brew --prefix gcc)/bin/gcc-ar-11 -DCMAKE_RANLIB=$(brew --prefix gcc)/bin/gcc-ranlib-11 -DOBJCOPY_PATH=$(brew --prefix binutils)/bin/objcopy -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
cmake --build . --config RelWithDebInfo
# The resulting binary will be created at: ./programs/clickhouse

Caveats

If you intend to run clickhouse-server, make sure to increase the system’s maxfiles variable.

:::note
You’ll need to use sudo. :::

To do so, create the /Library/LaunchDaemons/limit.maxfiles.plist file with the following content:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
        "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>Label</key>
    <string>limit.maxfiles</string>
    <key>ProgramArguments</key>
    <array>
      <string>launchctl</string>
      <string>limit</string>
      <string>maxfiles</string>
      <string>524288</string>
      <string>524288</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>ServiceIPC</key>
    <false/>
  </dict>
</plist>

Give the file correct permissions:

sudo chown root:wheel /Library/LaunchDaemons/limit.maxfiles.plist

Validate that the file is correct:

plutil /Library/LaunchDaemons/limit.maxfiles.plist

Load the file (or reboot):

sudo launchctl load -w /Library/LaunchDaemons/limit.maxfiles.plist

To check if it’s working, use the ulimit -n or launchctl limit maxfiles commands.

Running ClickHouse server

cd ClickHouse
./build/programs/clickhouse-server --config-file ./programs/server/config.xml
